Hi,
In order to restrict user to enter numeric or decimalised value in the
textbox. We have comparevalidator in ASP.NET. But If u want not to enter any
non-numeric value then I have code to validate enter data in client side.
I am attaching the file that contains the code to enter only numeric data.
Kindly give me feedback about this code, it work or not
