hi guys

I want to add an event listener to a datagrid column but it doesnt seem to work
My code:

public class TradeGrid extends VBox implements IComponent
{
private function buildColumnModel(complexheaders:Object,fields:Object):void{
//This works
dataGrid.addEventListener(flash.events.KeyboardEvent.KEY_UP,populate);// works fine
}

private function createColumn(columnIndex:int,fieldObject:Object):AdvancedDataGridColumn{
var column:AdvancedDataGridColumn = new AdvancedDataGridColumn();
column.addEventListener(flash.events.KeyboardEvent.KEY_UP,populate);// Does not work
return column;
}

private function populate(event: flash.events.KeyboardEvent) : void {      
PopUpManager.addPopUp(LookUp.dataGrid, this, false); //popup the grid            
         }
}      

Any ideas?

Thanks

DataGridColumn just doesn't dispatch any Keyboard events. In fact, the only events it dispatches are flash.events.Event.ACTIVATE and flash.events.Event.DEACTIVATE, which it inherits from EventDispatcher. The reason that DataGrid does dispatch Keyboard events is because it inherits them from InteractiveObject.

I haven't tested this, but it might be that column.itemRenderer.addEventListener(KeyboardEvent.KEY_UP,populate); might work?

And why you call your class as TradeGrid and extended from VBox instead DataGird?

public class TradeGrid extends VBox
