Hi,

Try the following JavaScript to allow only numbers in RadTextBox.
JS:
function OnKeyPress(sender, args)
{
     var text = sender.get_value() + args.get_keyCharacter();
     if (!text.match('^[a-z]+$'))
     args.set_cancel(true);
}

Thanks,
Shinu.

Hello srinivas,

On first look the Shinu's solution will work perfectly client side. You will need to validate the values server side also. You can do this by checking the .Text property of RadTextBox manually, or still use asp:Validator for this purpose.

For using asp:validators in combination with RadInput controls see these resources:
