Take 3... after further review, to simplify things I have bound 2
separate ArrayCollection to separate DataGrids they both share one
common field - Ticker.. I'd like to select the corresponding row
programmatically in the second datagrid which contains the value for
'Ticker' that is selected in the first datagrid.
So far this does not work...
<mx:DataGrid id=dg1 click='onClick()" />
<mx:DataGrid id=dg2 />
private function onClick(): void {
var curTick:String = dg1.selectedItem.Ticker;
dg2.selectedItem.Ticker = curTick;
dg2.selectedIndex= dg2.selectedItem.Ticker.rowindex;
}
Any suggestions?... Anyone??
I imagine the ListCollection will work but not sure the syntax.
