Hi,

Not really. I mean you could try trapping the KeyDown event and cancel it (mark the event args handled) for any non-numeric keys. You would probably have to do this for the TextBox in the cell, though, and not the grid itself. I'm not absolutely sure. But then you would also have to allow any other valid keys like the arrow keys. then there's copy and paste to consider, as well as Delete. It get complicated pretty fast.

If the DataType of the column is a double, then the user's entry will be validated when they try to leave the cell. But not as they type.
