Handling ctrl+double click in a datagrid

Question

Hi all
I want to have a different action if I double-click a row in a data grid, or hold down ctrl while double-clicking. If I double-click then the selectedItem property of the datagrid is populated even if I don't single-click the row first. But if hold ctrl, that selecteditem is null unless I single-click first to select the row. Does anyone know why this is so or if there is a way round it? It's ugly to have to select, hit Ctrl then double click.
Thanks
Martin
Code:
public function registerInterest():void {
        adg1.addEventListener(MouseEvent.DOUBLE_CLICK, handleGridClick);
public function handleGridClick(event:MouseEvent):void {
    if (event.ctrlKey) { doSomething() } else { doSomethingDifferent();

Answer 1

I have two dynpros:
- In the first, in PBO I do
    CALL METHOD grid1->set_table_for_first_display
To display the ALV
- When I do double-clic, I raise the event handle_double_click. In the event I do a
  CALL SCREEN 2000 STARTING AT d_left_d d_top_d ENDING AT y1 y2
to get the details. then, in the screen 2000, in the PBO, I do another
   CALL METHOD grid2->set_table_for_first_display
to display the second ALV, the details.
Regards.
