The beginning of the Drag from AdvancedDataGrid can be caught using the "dragStart" event on the grid. In the event handler for this method, make any changes you need. You may also want to check out the following events of the AdvancedDataGrid:
thanx for the reply
unfortunately, I'd already tried that.
For some reason i don't understand, i can't catch the event. don't know if it's because it's never dispatched or what.
As i said in my OP, i'm using hierarchical data. I'm also using a renderer.
I've managed to have the destination grid (which i changed to an AdvancedDataGrid) accept the drop, but when i drop the element, i get an error in the AdvancedDataGrid class, in the addItemsToTarget function
for (var i:int = n - 1; i >= 0; i--)
where targetADG._dropData is null.
I have exatcly the same problem,
Why the event has no relatedObject in this case
How to do to?
