I have a windows form that contains two datagrids (framework 2.0/).
I would like to limit two of the columns to numeric entries only.  IE
If the user types a letter or anything other than 0123456789. then I
want to supress the key.

I have tried turning on keypreview on the form (I'm using this method
to limit entries in other textboxes/controls) but this method does not
capture the keys once the datagrid goes into "edit mode".

Ideas on how to do this would be great.

BTW: When you set the format option of the datgrid column to format for
numeric, it still allows the end user to type alpha characters (a-z).

Thanks
Rick
