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>

Descrizione delle proprietà
children | proprietà |
public var children:Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
An Array of AdvancedDataGridColumn instances that define the columns of the column group.
childrenDragEnabled | proprietà |
public var childrenDragEnabled:Boolean = true| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Il valore predefinito è true.
Descrizione della funzione di costruzione

Descrizione dei metodi
itemToData | () | metodo |
public function itemToData(data:Object):*| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
data:Object — The data provider element.
|
* — The data from the data provider for the specified Object.
