Hi,
I usually subclass the DataGridColumn class to customize the assigned cell
renderer. This way you can easily pass extra information (in your case the
dataprovider for the combo boxes) directly to the column. The cellrenderer then
"asks" its row for the dataprovider to use:
<mx:DataGrid ... >
<mx:columns>
<my:ExtendedDataGridColumn cellRenderer="ComboRenderer"
dataProvider="{arr1}"/>
<my:ExtendedDataGridColumn cellRenderer="ComboRenderer"
dataProvider="{arr2}"/>
<my:ExtendedDataGridColumn cellRenderer="ComboRenderer"
dataProvider="{arr3}"/>
</mx:columns>
</mx:DataGrid>
ExtendedDataGridColumn just extends the mx.controls.gridclasses.DataGridColumn
class and adds a public variable dataProvider.
Inside the cellRenderer class ComboRenderer (which you could implement as a
direct subclass of mx.controls.ComboBox) you can then access the correct
dataProvider by doing this
function init():Void {
super.init();
dataProvider = listOwner.getColumnAt(getCellIndex().columnIndex);
}
