The
DataGrid
control is like a List except that it can
show more than one column of data making it suited for showing
objects with multiple properties.
The DataGrid control provides the following features:
- Columns of different widths or identical fixed widths
- Columns that the user can resize at runtime
- Columns that the user can reorder at runtime
- Optional customizable column headers
- Ability to use a custom item renderer for any column to display data other than text
- Support for sorting the data by clicking on a column
The DataGrid control has the following default sizing characteristics:
Characteristic | Description |
---|---|
Default size | If the columns are empty, the default width is 300 pixels. If the columns contain information but define no explicit widths, the default width is 100 pixels per column. The DataGrid width is sized to fit the width of all columns, if possible. The default number of displayed rows, including the header is 7, and each row, by default, is 20 pixels high. |
Minimum size | 0 pixels. |
Maximum size | 5000 by 5000. |
The <mx:DataGrid>
tag inherits all of the tag
attributes of its superclass, except for labelField
,
iconField
, and iconFunction
, and adds the
following tag attributes:

columns | 屬性 |
columns:Array
[覆寫] 語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
An array of DataGridColumn objects, one for each column that can be displayed. If not explicitly set, the DataGrid control attempts to examine the first data provider item to determine the set of properties and display those properties in alphabetic order.
If you want to change the set of columns, you must get this array, make modifications to the columns and order of columns in the array, and then assign the new array to the columns property. This is because the DataGrid control returned a new copy of the array of columns and therefore did not notice the changes.
此屬性可以做為資料繫結的來源。一旦修改此屬性,將傳送 columnsChanged
事件。

A flag that indicates whether or not the user can edit
items in the data provider.
If true
, the item renderers in the control are editable.
The user can click on an item renderer to open an editor.
You can turn off editing for individual columns of the
DataGrid control using the DataGridColumn.editable
property,
or by handling the itemEditBeginning
and
itemEditBegin
events
預設值為 false。

editedItemPosition | 屬性 |
editedItemPosition:Object
語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
The column and row index of the item renderer for the data provider item being edited, if any.
This Object has two fields, columnIndex
and
rowIndex
,
the zero-based column and row indexes of the item.
For example: {columnIndex:2, rowIndex:3}
Setting this property scrolls the item into view and
dispatches the itemEditBegin

horizontalScrollPosition | 屬性 |
horizontalScrollPosition:Number
[覆寫] 語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
The offset into the content from the left edge.
This can be a pixel offset in some subclasses or some other metric
like the number of columns in a DataGrid control.
The DataGrid scrolls by columns so the value of the
horizontalScrollPosition
property is always
in the range of 0 to the index of the columns
that will make the last column visible. This is different from the
List control that scrolls by pixels. The DataGrid control always aligns the left edge
of a column with the left edge of the DataGrid control.
實作

The flash.system.IMEConversionMode class defines constants for the
valid values for this property.
You can also specify null
to specify no IME.
預設值為 null。

itemEditorInstance | 屬性 |
public var itemEditorInstance:IListItemRenderer
語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
A reference to the currently active instance of the item editor, if it exists.
To access the item editor instance and the new item value when an
item is being edited, you use the itemEditorInstance
property. The itemEditorInstance
property
is not valid until after the event listener for
the itemEditBegin
event executes. Therefore, you typically
only access the itemEditorInstance
property from within
the event listener for the itemEditEnd
event.
The DataGridColumn.itemEditor
property defines the
class of the item editor
and, therefore, the data type of the item editor instance.
You do not set this property in MXML.
minColumnWidth | 屬性 |
minColumnWidth:Number
語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
The minimum width of the columns, in pixels. If not NaN, the DataGrid control applies this value as the minimum width for all columns. Otherwise, individual columns can have their own minimum widths.
預設值為 NaN。
實作
public function get minColumnWidth():Number

A flag that indicates whether the user can change the size of the
columns.
If true
, the user can stretch or shrink the columns of
the DataGrid control by dragging the grid lines between the header cells.
If true
, individual columns must also have their
resizable
properties set to false
to
prevent the user from resizing a particular column.
預設值為 true。
sortableColumns | 屬性 |
public var sortableColumns:Boolean = true
語言版本: | ActionScript 3.0 |
產品版本: | Flex 3 |
執行階段版本: | Flash Player 9, AIR 1.1 |
A flag that indicates whether the user can sort the data provider items
by clicking on a column header cell.
If true
, the user can sort the data provider items by
clicking on a column header cell.
The DataGridColumn.dataField
property of the column
or the DataGridColumn.sortCompareFunction
property
of the column is used as the sort field.
If a column is clicked more than once
the sort alternates between ascending and descending order.
If true
, individual columns can be made to not respond
to a click on a header by setting the column's sortable
property to false
.
When a user releases the mouse button over a header cell, the DataGrid
control dispatches a headerRelease
event if both
this property and the column's sortable property are true
.
If no handler calls the preventDefault()
method on the event, the
DataGrid sorts using that column's DataGridColumn.dataField
or
DataGridColumn.sortCompareFunction
properties.
預設值為 true。

type
property of the event object for a
itemEditBegin
event, which indicates that an
item is ready to be edited.
The default listener for this event performs the following actions:
- Creates an item editor object by using a call to the
createItemEditor()
method. - Copies the
data
property from the item to the editor. By default, the item editor object is an instance of the TextInput control. You use theitemEditor
property of the list control to specify a custom item editor class. - Set the
itemEditorInstance
property of the list control to reference the item editor instance.
You can write an event listener for this event to modify the data passed to the item editor. For example, you might modify the data, its format, or other information used by the item editor.
You can also create an event listener to specify the item editor used to edit the item. For example, you might have two different item editors. Within the event listener you can examine the data to be edited or other information, and open the appropriate item editor by doing the following:
- Call
preventDefault()
to stop Flex from calling thecreateItemEditor()
method as part of the default event listener. - Set the
itemEditor
property to the appropriate editor. - Call the
createItemEditor()
method.
The properties of the event object have the following values:

property of the event object for a
itemEditBeginning
event, which indicates that the user has
prepared to edit an item, for example, by releasing the mouse button
over the item.
The default listener for this event sets the DataGrid.editedItemPosition
property to the item that has focus, which starts the item editing session.
You typically write your own event listener for this event to
disallow editing of a specific item or items.
Calling the preventDefault()
method from within your own
event listener for this event prevents the default listener from executing.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the

The DataGridEvent.ITEM_EDIT_END constant defines the value of thetype
property of the event object for a
itemEditEnd
event, which indicates that an edit
session is ending.
The list components have a default handler for this event that copies the data from the item editor to the data provider of the list control. The default event listener performs the following actions:
- Uses the
editorDataField
property of the DataGridColumn associated with this event to determine the property of the item editor containing the new data and updates the data provider item with that new data. Since the default item editor is the TextInput control, the default value of theeditorDataField
property is"text"
, to specify that thetext
property of the TextInput contains the new item data. - Calls the
destroyItemEditor()
method to close the item editor.
You typically write an event listener for this event to perform the following actions:
- In your event listener, you can modify the data returned by the editor
to the list component. For example, you can reformat the data before returning
it to the list control. By default, an item editor can only return a single value.
You must write an event listener for the
itemEditEnd
event if you want to return multiple values. - In your event listener, you can examine the data entered into the item editor.
If the data is incorrect, you can call the
preventDefault()
method to stop Flex from passing the new data back to the list control and from closing the editor.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the
