DataGridTextBox OnKeyPress

[Shravan]

Hi All,
I wrote my own columnstyle for hosting textbox in which
I used the textbox which is a extended version of
DataGridTextBox, everything is OK except that in textbox
in OnKeyPress method when I call base.OnKeyPress it is
throwing exception in TextBox WndProc, the exception says

"Object reference not set to an instance of an object"

I could get no more clue from it.

I saw a posting related to this problem in

but I could not understand the solution neither I could
solve from it.

Anybody please help.

Thanks,
Shravan.
