Answer 1

As far as I am aware there's nothing native in the .NET framework (2.0 at least) to do this. Your options would be:

1. Create a custom control which inherits from the textbox control and only allows numeric input. This has the advantage that the control can be reused.
2. Handle the KeyPress event and check the charCode to only allow numeric keystrokes. This is easier but much less reusable.
