Use a CompareValidator:
- set the ControlToValidate property to the textbox you want to validate
- set the Operator property to DataTypeCheck
- set the Type property to Integer
- don't forget to set the ErrorMessage text

Note 1: an empty textbox still satisfies the CompareValidator (add a
RequiredFieldValidator to prevent this)
Note 2: the value returned from the textbox is still a "text", so you need
an Int32.Parse() to convert to a real integer
