    I have an application where I need to input a number in to a box.

    It then performs a calculation. The problem is that you can also put letters in there which causes an issue.

    Is there a checkbox somewhere so that only numbers can be entered? I can't seem to find one in the designer.

    Or maybe some simple code that when that box is focused, only number presses are accepted?

    Thanks
