routedevents

Hi all,

I've PreviewMouseDown event on TreeView in order to determine if user can select other item based on some logic. If the current item data changed, will appear MessageBox that asks the user if he want to discard the changes. if user press YES , I set e.Handled = false; to enable the new selection. and if user press NO, I set e.Handled = true; to cancel the new selection.

The problem is that although I set e.Handled = false , the event stop and no selection event occurs on TreeView. Someone has solution for that?

Thanks in advance!
