Item renderers are associated with each column of a grid.
Set the item renderer for a column by using
the GridColumn.itemRenderer property
.
By default, an item renderer does not clip to the boundaries of the cell.
If your renderer extends past the bounds of the cell, you can set
clipAndEnableScrolling
to true
to clip the renderer to the bounds
of the cell.
Transitions in DataGrid item renderers aren't supported. The GridItemRenderer class
has disabled its transitions
property so setting it will have no effect.
Efficiency Considerations
DataGrid scrolling and startup performance are directly linked to item renderer complexity and the number of item renderers that are visible within the DataGrid's scroller. Custom GridItemRenderer instances are used and reused repeatedly so it's important to define them as simply and efficiently as possible.
If an item renderer's responsibility is limited to displaying
one or more lines of text, then developers should seriously
consider using the DefaultItemRenderer class which does so very
economically (an application that's only going to be deployed on
Windows one can gain some additional performance by using the
UITextFieldGridItemRenderer class instead). The most efficient
way to use GridItemRenderer to display the GridColumn's dataField
as text is to identify the GridItemRenderer's text displaying
element with id="labelDisplay"
. The labelDisplay
component must be a TextBase
subclass like
Label
or RichText
. You might take this
approach, instead of just using DefaultGridItemRenderer, if your
item renderer included some additional elements that did not
depend on the item renderer's data, like borders or other graphic
elements.
An item renderer that contains more than one visual element
whose properties depend on the item renderer's data can use data
binding to define the values of those properties. This approach
yields MXML code that's straightforward to read and maintain and
its performance may be adequate if the number of visible item
renderers is limited (see the DataGrid requestedRowCount
and requestedColumnCount
properties). The most efficient
way to configure this kind of item renderer is to override its
prepare()
method and do the work there. The
renderer's prepare()
method is called each time the
renderer is redisplayed and so it's important that it's coded
efficiently. If your item renderer is stateful, for example if it
caches internal values, you can clear its state in its
discard()
method. The discard()
method
is called each time the renderer is moved to the DataGrid's
internal free list, where it's available for reuse.
GridItemRenderers should be as simple as possible. To gain the
best possible performance, minimize the number of components, and
the depth of the hierarchy. If it's practical, use explicit
positions and sizes rather than constraints to define the layout.
DataGrid's with variableRowHeight="false"
(the
default) tend to perform better, likewise for
showDataTips="false"
(the default) and
clipAndEnableScrolling="false"
(the default).
Examples of the various GridItemRenderer configurations described here are available in the examples section.

This property can be used as the source for data binding. When this property is modified, it dispatches the selectedChanged
event.
Implementation

public function set selected(value:Boolean):void
showsCaret | property |
showsCaret:Boolean
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Contains true
if the item renderer's cell is indicated by the caret.
Unlike a List item renderer, grid item renderers do not have exclusive responsibility for displaying something to indicate their cell or row has the caret. The Grid itself automatically displays the caretIndicator skin part for the caret row or cell. The item renderer can also change its visual properties to emphasize that it has the caret.
The default value is false.
This property can be used as the source for data binding. When this property is modified, it dispatches the showsCaretChanged
event.
Implementation
public function get showsCaret():Boolean
public function set showsCaret(value:Boolean):void
GridItemRenderer | () | Constructor |
public function GridItemRenderer()
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Constructor.
discard | () | method |
public function discard(willBeRecycled:Boolean):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Called from the item renderer parent's updateDisplayList()
method
when it has been determined that this renderer will no longer be visible.
If the willBeRecycled
parameter is true
,
then the owner adds this renderer to its internal free list for reuse.
Implementations can use this method to clear any renderer properties that are no longer needed.
This method is not intended to be called directly. It is called by the DataGrid implementation.
Parameters
willBeRecycled:Boolean — true if this renderer is going to be added
to the owner's internal free list for reuse.
|
getCurrentRendererState | () | method |
protected function getCurrentRendererState():String
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Returns the name of the state to be applied to the renderer. For example, a basic item renderer returns the String "normal", "hovered", or "selected" to specify the renderer's state. If dealing with touch interactions (or mouse interactions where selection is ignored), "down" and "downAndSelected" can also be returned.
A subclass of GridItemRenderer must override this method to return a value if the behavior desired differs from the default behavior.
In Flex 4.0, the 3 main states were "normal", "hovered", and "selected". In Flex 4.5, "down" and "downAndSelected" have been added.
The full set of states supported (in order of precedence) are:
- dragging
- downAndSelected
- selectedAndShowsCaret
- hoveredAndShowsCaret
- normalAndShowsCaret
- down
- selected
- hovered
- normal
String — A String specifying the name of the state to apply to the renderer.

prepare | () | method |
public function prepare(hasBeenRecycled:Boolean):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Called from the item renderer parent's updateDisplayList()
method
after all of the renderer's properties have been set.
The hasBeenRecycled
parameter is false
if this renderer has not been used before, meaning it was not recycled.
This method is called when a renderer is about to become visible
and each time it's redisplayed because of a change in a renderer
property, or because a redisplay was explicitly requested.
This method can be used to configure all of a renderer's visual
elements and properties.
Using this method can be more efficient than binding data
properties to visual element properties.
Note: Because the prepare()
method is called frequently,
make sure that it is coded efficiently.
The prepare()
method may be called many times
before the discard()
method is called.
This method is not intended to be called directly. It is called by the DataGrid implementation.
Parameters
hasBeenRecycled:Boolean — true if this renderer is being reused.

dataChange | Event |
mx.events.FlexEvent
property FlexEvent.type =
mx.events.FlexEvent.DATA_CHANGE
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4.5 |
Runtime Versions: | Flash Player 10, AIR 2.5 |
Dispatched when the data
property changes.
FlexEvent.DATA_CHANGE
constant defines the value of the
type
property of the event object for a dataChange
event.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
<?xml version="1.0" encoding="utf-8"?> <!-- Demonstate how to control text wrapping in DataGrid GridItemRenderer item renderer. This DataGrid example demonstrates how to control text wrapping with a simple custom item renderer based on GridItemRenderer. All cells in this example display the same lengthy string which does not contain newlines. Note that the Flex text components unconditionally render newline characters that appear in the text. The "Label Renderer" column's renderer is a custom GridItemRenderer that displays its text with an s:Label component. We use the Label's maxDisplayedLines property to control line breaking and to include "..." truncation when the single line of text doesn't fit. Note also: this example's column widths and row heights are defined by the DataGrid's typicalItem. The typical item uses explicit newlines to create a string that occupies three lines and a reasonable column width. --> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Declarations> <fx:String id="sampleText">Lorem Ipsum is the standard dummy text of the typesetting industry.</fx:String> <fx:int id="maxDisplayedLines">0</fx:int> </fx:Declarations> <s:Panel title="Spark DataGrid Control Example which demonstrates how to control text wrapping in a GridItemRenderer" width="75%" height="75%" horizontalCenter="0" verticalCenter="0"> <s:controlBarContent> <s:VGroup> <s:CheckBox id="vrh" selected="@{dataGrid.variableRowHeight}" label="dataGrid.variableRowHeight={vrh.selected}"/> <s:CheckBox id="lb" selected="true" valueCommit="maxDisplayedLines=(lb.selected) ? 0 : 1" label="labelRenderer.maxDisplayedLines={maxDisplayedLines}"/> </s:VGroup> </s:controlBarContent> <s:DataGrid id="dataGrid" variableRowHeight="false" verticalCenter="0" horizontalCenter="0"> <s:columns> <s:ArrayList> <!-- Simple custom item renderer based on GridItemRenderer and Label.

<?xml version="1.0" encoding="utf-8"?> <!-- Examples of custom GridItemRenderers that use data binding to configure visual properties. The application's control bar slider can be used to change the the dataProvider items. The GridItemRenderer class is a Group that implements IGridItemRenderer and can be used as the top level "container" for a custom item renderer. Its data property is the dataProvider item for the row the item renderer appears on and its components can configure themselves by binding to the data property, or by overriding the renderer's prepare() method and configuring themselves imperatively with ActionScript code. All of the item renderers in this example use binding, which makes the code a little easier to read and modify. It's also less efficient than using a prepare() method override. The performance difference is most noticeable when the DataGrid is configured so that a large number of item renderers are visible. DataGrid item renderers are always sized to exactly fit the cell that they're rendering: their size matches the width of their column and the height of their row. The DataGrid enables interactive column resizing by default, so all of the item renderers need to defend against the possibility that their width will become arbitrarily small. The first column's item renderer just contains a Label. By specifying maxDisplayedLines="1" we ensure that the Label will truncate its text to fit the width it's given. The other columns' item renderers specify clipAndEnableScrolling="true" which just means that their fixed size contents will always be clipped to the bounds of the GridItemRenderer. This property -enables- scrolling, which means that one could actually scroll the contents of the item renderers when their width gets small, by setting the renderer's horizontalScrollPosition property. We do not do as much here. The "Name" column's item renderer demonstrates a special case: if the renderer contains a text component with id="labelDisplay", GridItemRenderer automatically sets the labelDisplay's text property to the value of data[column.dataField] per the GridItemRenderer label property. The first colunm also demonstrates using the styleName property to configure the Label's left, right, top, and fontSize styles. The "Statistics" column's item renderer demonstrates how binding can be used to configure the geometry of graphic elememnts. The data items' min, max, and value properties have been normalized to the range [0 100] to keep the bindings simple. The "Value" column's item renderer allows one to change data item's value property with a Slider. The "Call" column's item renderer demonstrates a slightly more complicated component layout and it also demonstates how the data item's value can be both displayed and edited. --> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Script> <![CDATA[ // Incrementally change all of the date items' min, max, value, and call properties. private function changeData(delta:Number):void { for each (var item:Object in dataGrid.dataProvider) { item.value = (item.value + delta) % 100; item.min = item.value * 0.5; item.max = item.value + ((100 - item.value) * 0.5); item.call = item.value > 50; } } ]]> </fx:Script> <fx:Style> .nameColumn { fontSize: 18; left: 5; right: 5; top: 9; } </fx:Style> <s:Panel title="Spark DataGrid Control Example of custom GridItemRenderers that use data binding to configure visual properties" width="75%" height="75%" horizontalCenter="0" verticalCenter="0"> <s:controlBarContent> <s:HGroup verticalAlign="baseline"> <s:Label text="Shake Data"/> <s:HSlider id="hsl" minimum="0" maximum="25" change="changeData(hsl.value)"/> </s:HGroup> </s:controlBarContent> <s:DataGrid id="dataGrid" left="5" right="5" top="5" bottom="5"> <s:columns> <s:ArrayList> <!-- By specifying id="labelDisplay" the Label component's text property is automatically set to the renderer's label, which is effectively the value of the item's name property.
