AdvancedDataGrid.columnGroup
property
takes an Array of AdvancedDataGridColumnGroup instances to specify the column groups.
The following example uses the AdvancedDataGridColumnGroup class to define a column group named Revenues that contains two columns: Actual and Estimate.
<mx:AdvancedDataGrid id="myADG" dataProvider="{dpFlat}" width="100%" height="100%"> <mx:groupedColumns> <mx:AdvancedDataGridColumn dataField="Region"/> <mx:AdvancedDataGridColumn dataField="Territory"/> <mx:AdvancedDataGridColumn dataField="Territory_Rep" headerText="Territory Rep"/> <mx:AdvancedDataGridColumnGroup headerText="Revenues"> <mx:AdvancedDataGridColumn dataField="Actual"/> <mx:AdvancedDataGridColumn dataField="Estimate"/> </mx:AdvancedDataGridColumnGroup> </mx:groupedColumns> </mx:AdvancedDataGrid>MXML-syntaxisMXML-syntaxis verbergen
You use the <mx.AdvancedDataGridColumnGroup>
tag to configure a column
group of a AdvancedDataGrid control.
You specify the <mx.AdvancedDataGridColumnGroup>
tag as a child
of the groupedColumns
property in MXML.
The <mx.AdvancedDataGridcolumn>
tag defines the following tag attributes:
<mx:AdvancedDataGridColumn Properties children="No default" childrenDragEnabled="true|false" />

children | eigenschap |
public var children:Array
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
An Array of AdvancedDataGridColumn instances that define the columns of the column group.
childrenDragEnabled | eigenschap |
public var childrenDragEnabled:Boolean = true
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
Specifies whether the child columns can be dragged to reposition them in the group.
If false
, child columns cannot be reordered even if
the AdvancedDataGridColumn.dragEnabled
property is set
to true
for a child column.
De standaardwaarde is true.
AdvancedDataGridColumnGroup | () | Constructor |
public function AdvancedDataGridColumnGroup(columnName:String = null)
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
Constructor.
ParameterscolumnName:String (default = null ) — The name of the field in the data provider
associated with the column group, and the text for the header cell of this
column. This is equivalent to setting the dataField
and headerText properties.
|
itemToData | () | methode |
public function itemToData(data:Object):*
Taalversie: | ActionScript 3.0 |
Productversie: | Flex 3 |
Runtimeversies: | Flash Player 9, AIR 1.1 |
Returns the data from the data provider for the specified Object.
This method is useful when the data for a row contains nested Objects. For example, a row is defined by the following data in the data provider:
row = { name:"Adobe", address : { street : "345 Park Avenue", city : "San Jose", state : "CA 95110", country : "USA" } }
You then assign the "address" field to the dataField
property
of the AdvancedDataGridColumnGroup instance. A call to itemToData(row)
then returns the address object.
This method is similar to the
AdvancedDataGridColumn.itemToLabel()
method.
Parameters
data:Object — The data provider element.
|
* — The data from the data provider for the specified Object.
