Help in fixing the error "Input string is not in correct format"

I have a true DB grid bounded . Whenevr I paste some string value in a field that is bind with some numeric field an error message appears "Input string is of incorrect format".

I dnt want this message to appear but i want to handle it by myself means i wanna display me own message.

plz any one can help me ...... Thnx in advance

In the DataGridView you handle the DataError event to provide your own error message. I would assume that most other grids provide a similar event for the same purpose. I suggest you check your documentation for the same.
