Cell validating cancel

I'm using a Data Grid View in my Win Forms application. Process Dialog Key(key Data) End Function No, but you can manually fire the Cell Validating event. All events are is a class using the Observer Pattern, they're no different than any other method.My main objective is to make the Enter key not move to the next row in the grid. If that doesn't work, you can create a Key Press event on the cell and emulate pressing Enter on the cell, but that may mess with the users UI, just put the carat back where it was.

Its not permissible to have the two selected to true, but they can both be false. I guess I could call On Cell Validating, but then I'd be worried I'm missing some other event. Keys) As Boolean Dim key As Keys = (key Data And Keys. What I really want is some flavour of End Edit() that behaves just like pressing enter on the last row of a grid with adding disabled. my version is a slight different from yours, because when i move to the other cell, and my code returns e.cancel=false in the cell validating event, an error will be generated, says that: "operation did not succeed, because the program cannot commit or quit a cell value change". this is my code: Protected Overrides Function Process Dialog Key(By Val key Data As System. You can choose from three types of error alerts: Warn users that the data they entered is invalid, without preventing them from entering it. The problem is now, that the error-symbol (and the error text) is not displayed (in the cell). Cancel the cell looses the focus and error-symbol is displayed.
