formatable datagrid column - accepts only digits

Question

Hi I'd like to add to my datagrid a column that allows only digits to be entered in. How can I implement this? Thanks Stoyka

2 ways I can think to do this off the top of my head. First would be to set up a new event that is triggered when a key is pressed in the datagrid and have it valiadate the string in the cell each time. That way is probably easier but is probably less correct. The approach that I would take(unless it doesnt turn out to work) would be to to make a new class that inheireites from DataGridRow(or whatever it is called!) and instead of using a textbox use a masked textbox and set it to only allow numbers. THen set your datagrid to use your new class instead of the default.
