Hi,
I have widely used RadNumericTextBox in my application. I want to restrict the user to enter negative value in the RadNumericTextBox without set to MinValue = 0. We can set MinValue=0 but in this case also user can enter the negative value however it will be set to 0 by default.
But i don't want to allow the user to enter negative values in entire application. Can anyone have solution to solve this issue ?

Hi Nileshkumar,

If you want to restrict the user from entering the minus (-) character into the RadNumericTextBox, try attaching the following JavaScript code to the OnKeyPress Client event of the control.

JavaScript:
<script type="text/javascript">
    function keypress(sender, args) {
        if ((args.get_keyCode() == 109) || (args.get_keyCode() == 45)) {
            args.set_cancel(true);
        }
    }
</script>

Thanks,
Princy.
