ListView out of range exception

[Pengyu]

Whenever I call listView.RemoveAt(listView.Count-1),
which remove the last item, I get an out of range
exception. How to solve this problem?

Thanks a lot,

Pengyu.

Where are you calling this from? Are you calling this from a click or other
event of the listview? Listview tries to access itself after the event, so if
you remove the last item it cannot access it and triggers this error.

Its a real PITA with the list view.

I called it from a click event.

I called it from a click event.

Yep - thats it. Its a "Design flaw" in the treeview. You have to post a
delayed event and delete it AFTER the click event has returned.
