Do you mean that you want your page to fail validation at postback if there
are non-numeric characters in the textbox, or do you want to prevent your
users from physically typing in non-numeric characters?

Assuming the former, that's fairly easy with a validator and a regular
expression.

Assuming the latter, you'll have to create a client-side JavaScript function
called by the onmousedown() event of the textbox which disallows non-numeric
characters...

Woops - I meant, of course, the onkeypress() event!

This might help you...
