Deepa,
I just experienced that the TreeViewDataBound
is pretty buggie. Basically when I call
the dataSet.tables["mytable"].clear() after
the TreeViewDataBound control is deleted, it has
null reference exception
I guess table.clear() is trying call the events
that was assoicated the deleted treeViewDataBound control.
I think the TreeViewDataBound need to handle
to clear all the DB_xxxEvent when the TreeViewDataBound control is delete (or disposed
if you want this word).
What do you think how sooon we have newer
version of TreeViewDataBound.
Thanks
