I would like to manipulate a cell in my Data Grid View when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.

This property returns the new value entered in the cell.

If it is less than five characters, you set the Error Text property of that cell to some error message.

Note that only the Cell Validating event can keep the editor active,when the validation fails and it does not allow the user to exit the cell until a valid value is filled.

However, pressing the Esc key in this situation will revert the initial value of the cell and it will close the editor. The Row Validating event has a slightly different behavior.

However sometimes it does break there during the clear and that of course causes problems. By turning multi-select off and changing the focus to a different cell before calling clear() I was able to fix the problem.

Does anyone have any ideas as to what might be causing this problem? Header Text; switch (header Text) { case "Number": if (!

Canceling this event prevents the user from exiting the cell until a valid value is entered or the edit process is canceled (via Esc key).

The Data Bound Item will be updated only if the cell is validated.

When the validation fails, the editor is closed, but the user cannot change the current row in the grid until a valid cell value is entered.
