Easy way of validating data in webForm textbox?

[VMI]

Is there an easy way for me to validate what's entered in a webForm
textbox? For example, how can I check that the user only enters a
number (and not letters) in a textbox?
I have VS 2005.
Thanks.

To test for a valid floating-point number, use Convert.ToSingle:
if it throws an exception [which you can catch], the number is not
valid.

Hello VMI,

use the standard asp.net validator controls
