I tried MessageBox or InstanceForm.showDialog that couldn work at Edited Event.
this is Sample Code.
sender, TreeNodeEditedEventArgs e)
DialogResult result = MessageBox.Show(
"will you change?"
(result != DialogResult.Ok)
at MessageBox.Show Line make Error Message.
attatch file is that window
So I tried make new thread and give to delay.. but that way
also if delay is so short or
when that action time
if I minimize or doesn focus.
that showed me similar Error.
Plz Give me a Solution.....
