I have a datagrid whith an itemrenderer which has an datagrid itself.What i want is when i select a row in the main datagrid to automatically select the first row of the itemrenderer datagrid. For example when a row is selected in the main datagrid the change event of it does

this.selectedItem.ItemRenderer.innerDatagrid.selectedIndex = 0
