Styles are either common or associated with a specific theme. If the style is common, it can be used with any theme. If a style is associated with a specific theme, it can only be used if your application uses that theme.
| Style | Description | Defined By | ||
|---|---|---|---|---|
alternatingItemColors | Type: Array Format: Color CSS Inheritance: Yes Language Version: ActionScript 3.0 Product Version: Flex 3 Runtime Versions: Flash9, AIR 1.1 The colors to use for the backgrounds of the items in the list. The value is an array of two or more colors. The backgrounds of the list items alternate among the colors in the array. For DataGrid controls, all items in a row have the same background color, and each row's background color is determined from the array of colors. For the TileList control, which uses a single list to populate a two-dimensional display, the style can result in a checkerboard appearance, stripes, or other patterns based on the number of columns and rows and the number of colors specified. TileList cycles through the colors, placing the individual item background colors according to the layout direction. If you have an even number of colors and an even number of columns for a TileList layed out horizontally, you will get striping. If the number of columns is an odd number, you will get a checkerboard pattern. Only takes effect if no undefined. | AdvancedListBase | ||

| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether you can allow more than one item to be
selected at the same time.
If true, users can select multiple items.
There is no option to disallow discontiguous selection.
Standard complex selection options are always in effect
(shift-click, control-click).
The default value is false.
Implementation
public function get allowMultipleSelection():Boolean public function set allowMultipleSelection(value:Boolean):voidanchorBookmark | property |
protected var anchorBookmark:CursorBookmark| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A bookmark to the item that is the anchor. A bookmark allows the component to quickly seek to a position in the collection of items. This property is used when selecting a set of items between the anchor and the caret or highlighted item, and when finding the selected item after a Sort or Filter is applied.
anchorIndex | property |
protected var anchorIndex:int = -1| Language Version: | ActionScript 3.0 |

caretIndicator | property |
protected var caretIndicator:Sprite| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The DisplayObject that contains the graphics that indicate which renderer is the caret.
caretItemRenderer | property |
protected var caretItemRenderer:IListItemRenderer| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The renderer for the item under the caret. In the selection model, there is an anchor, a caret and a highlighted item. When the mouse is being used for selection, the item under the mouse is highlighted as the mouse rolls over the item. When the mouse is clicked with no modifier keys (Shift or Control), the set of selected items is cleared and the item under the highlight is selected and becomes the anchor. The caret is unused in mouse selection.
If there is an anchor and another item is selected while using the Shift key, the old set of selected items is cleared, and all items between the item and the anchor are selected. Clicking items while using the Control key toggles the selection of individual items and does not move the anchor.
When selecting items using the keyboard, if the arrow keys are used with no modifier keys, the old selection is cleared and the new item is selected and becomes the anchor and the caret, and a caret indicator is shown around the selection highlight.
If the user uses arrow keys with the Shift key, the old selection is cleared and the items between the anchor and the new item are selected. The caret moves to the new item.
If arrow keys are used with the Control key, just the caret moves. The user can use the Space key to toggle selection of the item under the caret.
caretUID | property |
protected var caretUID:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The UID of the item under the caret.
collection | property |
protected var collection:ICollectionView| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
An ICollectionView that represents the data provider.
When you set the dataProvider property,
Flex wraps the data provider as necessary to
support the ICollectionView interface and
sets this property to the result.
The AdvancedListBase class then uses this property to access
data in the provider.
When you get the dataProvider property,
Flex returns this value.
columnCount | property |
columnCount:int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The number of columns to be displayed in a TileList control or items in a HorizontalList control. For the data grids, specifies the number of visible columns.
Note: Setting this property has no effect on a DataGrid control, which bases the number of columns on the control width and the individual column widths.
The default value is 4.
Implementation
public function get columnCount():int public function set columnCount(value:int):voidcolumnWidth | property |
columnWidth:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The width of the control's columns. This property is used by TileList and HorizontalList controls; It has no effect on data grid controls, where you set the individual column widths.
The default value is 50.
Implementation
public function get columnWidth():Number public function set columnWidth(value:Number):voiddata | property |
data:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The item in the data provider this component should render when this component is used as an item renderer or item editor. The list class sets this property on each renderer or editor and the component displays the data. ListBase-derived classes support this property for complex situations like having a List of DataGrids or a DataGrid where one column is a List.
The list classes use the listData property
in addition to the data property to determine what
to display.
If the list class is in a DataGrid it expects the dataField
property of the column to map to a property in the data
and sets selectedItem value to that property.
If it is in a List or TileList control, it expects the
labelField property of the list to map to a property
in the data, and sets selectedItem value to that property.
Otherwise it sets the selectedItem to the data itself.
This property uses the data provider but does not set it. In all cases, you must set the data provider in some other way.
You do not set this property in MXML.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataChange event.
Implementation

internal data structures on the next
updateDisplayList() call.
dataItemWrappersByRenderer | property |
protected var dataItemWrappersByRenderer:Dictionary| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A dictionary mapping item renderers to the ItemWrappers used to supply their data. Only applicable if a data effect is running.
dataProvider | property |
dataProvider:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Set of data to be viewed.
This property lets you use most types of objects as data providers.
If you set the dataProvider property to an Array,
it will be converted to an ArrayCollection. If you set the property to
an XML object, it will be converted into an XMLListCollection with
only one item. If you set the property to an XMLList, it will be
converted to an XMLListCollection.
If you set the property to an object that implements the
IList or ICollectionView interface, the object will be used directly.
As a consequence of the conversions, when you get the
dataProvider property, it will always be
an ICollectionView, and therefore not necessarily be the type of object
you used to you set the property.
This behavior is important to understand if you want to modify the data
in the data provider: changes to the original data may not be detected,
but changes to the ICollectionView object that you get back from the
dataProvider property will be detected.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the collectionChange event.

dataTipField | property |
dataTipField:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Name of the field in the data provider items to display as the
data tip. By default, the list looks for a property named
label on each item and displays it.
However, if the data objects do not contain a label
property, you can set the dataTipField property to
use a different property in the data object. An example would be
"FullName" when viewing a
set of people's names retrieved from a database.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataTipFieldChanged event.
Implementation
public function get dataTipField():String public function set dataTipField(value:String):voiddataTipFunction | property |
dataTipFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
User-supplied function to run on each item to determine its dataTip.
By default, the list looks for a property named label
on each data provider item and displays it.
However, some items do not have a label property
nor do they have another property that can be used for displaying
in the rows. An example is a data set that has lastName and firstName
fields, but you want to display full names. You can supply a
dataTipFunction that finds the appropriate
fields and return a displayable string. The
dataTipFunction is also good for handling formatting
and localization.
The dataTipFunction takes a single argument which is the item in the data provider and returns a String:
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataTipFunctionChanged event.
Implementation
public function get dataTipFunction():Function public function set dataTipFunction(value:Function):voiddefaultColumnCount | property |

The default value is 4.
dragEnabled | property |
dragEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether you can drag items out of
this control and drop them on other controls.
If true, dragging is enabled for the control.
If the dropEnabled property is also true,
you can drag items and drop them within this control
to reorder the items.
The default value is false.
Implementation
public function get dragEnabled():Boolean public function set dragEnabled(value:Boolean):voiddragImage | property |
dragImage:IUIComponent [read-only] | Language Version: | ActionScript 3.0 |

dragMoveEnabled | property |
dragMoveEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether items can be moved instead
of just copied from the control as part of a drag-and-drop
operation.
If true, and the dragEnabled property
is true, items can be moved.
Often the data provider cannot or should not have items removed
from it, so a MOVE operation should not be allowed during
drag-and-drop.
The default value is false.
Implementation
public function get dragMoveEnabled():Boolean public function set dragMoveEnabled(value:Boolean):voiddropEnabled | property |
dropEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether dragged items can be dropped onto the control.
If you set this property to true,
the control accepts all data formats, and assumes that
the dragged data matches the format of the data in the data provider.
If you want to explicitly check the data format of the data
being dragged, you must handle one or more of the drag events,
such as dragOver, and call the DragEvent's
preventDefault() method to customize
the way the list class accepts dropped data.
When you set dropEnabled to true,
Flex automatically calls the showDropFeedback()
and hideDropFeedback() methods to display the drop indicator.
The default value is false.
Implementation
public function get dropEnabled():Boolean public function set dropEnabled(value:Boolean):voidexplicitColumnCount | property |
protected var explicitColumnCount:int = -1| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |

iconField | property |
iconField:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The name of the field in the data provider object that determines what to display as the icon. By default, the list class does not try to display icons with the text in the rows. However, by specifying an icon field, you can specify a graphic that is created and displayed as an icon in the row. This property is ignored by DataGrid.
The renderers will look in the data provider object for a property of the name supplied as the iconField. If the value of the property is a Class, it will instantiate that class and expect it to be an instance of an IFlexDisplayObject. If the value of the property is a String, it will look to see if a Class exists with that name in the application, and if it can't find one, it will also look for a property on the document with that name and expect that property to map to a Class.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the iconFieldChanged event.
Implementation
public function get iconField():String public function set iconField(value:String):voidiconFunction | property |
iconFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A user-supplied function to run on each item to determine its icon. By default the list does not try to display icons with the text in the rows. However, by specifying an icon function, you can specify a Class for a graphic that will be created and displayed as an icon in the row.
The iconFunction takes a single argument which is the item
in the data provider and returns a Class.
Shown below is the signature of the function:
iconFunction(item:Object):Class
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the iconFunctionChanged event.
Implementation

The default item renderer depends on the component class. For example, the AdvancedDataGrid class uses AdvancedDataGridItemRenderer.
Implementation
public function get itemRenderer():IFactory public function set itemRenderer(value:IFactory):voiditemsNeedMeasurement | property |
protected var itemsNeedMeasurement:Boolean = true| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates whether the columnWidth
and rowHeight properties need to be calculated.
This property is set to true if a style changes that can affect the
measurements of the renderer, or if the data provider is changed.
itemsSizeChanged | property |
protected var itemsSizeChanged:Boolean = false| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates that the size of the renderers may have changed.
The component usually responds by re-applying the data items to all of
the renderers on the next updateDisplayList() call.
There is an assumption that re-applying the items will invalidate the
item renderers and cause them to re-measure.
iterator | property |
protected var iterator:IViewCursor| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The main IViewCursor instance used to fetch items from the data provider and pass the items to the renderers. At the end of any sequence of code, it must always be positioned at the topmost visible item being displayed.
iteratorValid | property |
protected var iteratorValid:Boolean = true| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates that a page fault as occurred and that
the iterator's position is not valid (not positioned at the topmost
item being displayed).
If the component gets a page fault (an ItemPending error),
it sets iteratorValid to false. Code that
normally handles the rendering of items checks this flag and does not
run until the page of data comes in from the server.
keySelectionPending | property |
protected var keySelectionPending:Boolean = false| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A flag that indicates if keyboard selection was interrupted by
a page fault. The component responds by suspending the rendering
of items until the page of data arrives.
The finishKeySelection() method will be called
when the paged data arrives
labelField | property |
labelField:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The name of the field in the data provider items to display as the label.
By default the list looks for a property named label
on each item and displays it.
However, if the data objects do not contain a label
property, you can set the labelField property to
use a different property in the data object. An example would be
"FullName" when viewing a set of people names fetched from a database.
The default value is "label".
This property can be used as the source for data binding. When this property is modified, it dispatches the labelFieldChanged event.
Implementation
public function get labelField():String public function set labelField(value:String):voidlabelFunction | property |
labelFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A user-supplied function to run on each item to determine its label.
By default, the list looks for a property named label
on each data provider item and displays it.
However, some data sets do not have a label property
nor do they have another property that can be used for displaying.
An example is a data set that has lastName and firstName fields
but you want to display full names.
You can supply a labelFunction that finds the
appropriate fields and returns a displayable string. The
labelFunction is also good for handling formatting and
localization.
For most components, the label function takes a single argument which is the item in the data provider and returns a String.
myLabelFunction(item:Object):String
The method signature for the data grid classes is:
myLabelFunction(item:Object, column:DataGridColumn):String
where item contains the DataGrid item object, and
column specifies the DataGrid column.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the labelFunctionChanged event.
Implementation
public function get labelFunction():Function public function set labelFunction(value:Function):voidlastDropIndex | property |
protected var lastDropIndex:int| Language Version: | ActionScript 3.0 |

protected var lastSeekPending:ListBaseSeekPending| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The most recent seek that caused a page fault. If there are multiple page faults, only the most recent one is of interest, as that is where to position the iterator and start rendering rows again.
listContent | property |
protected var listContent:AdvancedListBaseContentHolder| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
An internal display object that parents all of the item renderers,
selection and highlighting indicators and other supporting graphics.
This is roughly equivalent to the contentPane in the
Container class, and is used for managing scrolling.
listData | property |
listData:BaseListData| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
When a component is used as a drop-in item renderer or drop-in
item editor, Flex initializes the listData property
of the component with the additional data from the list control.
The component can then use the listData property
and the data property to display the appropriate
information as a drop-in item renderer or drop-in item editor.
You do not set this property in MXML or ActionScript; Flex sets it when the component is used as a drop-in item renderer or drop-in item editor.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataChange event.
Implementation
public function get listData():BaseListData public function set listData(value:BaseListData):voidRelated API Elements

The number of extra item renderers the layout algorithm can use when constructing animations for data effects. Changes that take place in the data provider corresponding to the items visible onscreen or this many items before or after the items onscreen will be subject to full effects processing. Items outside this range may not be animated perfectly by the effects.
A reasonable value for this property is approximately the number of rows visible onscreen. Setting it to a very large value may cause performance problems when used with a dataProvider with many items.
The default value is 0.

Usually, this method is called during mouse and keyboard handling when the set of data displayed by the item renderers hasn't yet changed.
Parameters
item:IListItemRenderer — An item renderer.
|
Point — A Point instance. The x property contains the column index
and the y property contains the row index.

itemToUID | () | method |
protected function itemToUID(data:Object):String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Determines the UID for a data provider item. All items in a data provider must either have a unique ID (UID) or one will be generated and associated with it. This means that you cannot have an object or scalar value appear twice in a data provider.
For example, the following data provider is not supported because the value "foo" appears twice and the UID for a string is the string itself:
var sampleDP:Array = ["foo", "bar", "foo"]
Simple dynamic objects can appear twice if they are two separate instances. The following is supported because each of the instances will be given a different UID because they are different objects:
var sampleDP:Array = [{label: "foo"}, {label: "foo"}]
Note that the following is not supported because the same instance appears twice:
var foo:Object = {label: "foo"};
sampleDP:Array = [foo, foo];
Parameters
data:Object — The data provider item.
|
String — The UID as a string.
