Positive (unsigned) integers only

[Chris]

Is there a way to make either the RadMaskedNumericInput or RadMaskedTextBox accept only non negative integers?

Hi Chris,

You can apply a minimum value to the RadMaskedNumericInput and RadMaskedCurrencyInput controls. More information on this approach you can find here.

Have a look at the tutorial and tel us know if it helps or if we can further assist you.

Hello!

I have the same problem, but solution above doesn't work. I'm getting ""maskedIput" is an undeclared prefix" error.

Hi Grzesiek,

I am not sure what is causing the error in your solution. This is why I attached a sample project demonstrating how to limit the MaskedInput control input to only positive numbers.

Let me know if it works for you or if I can further assist you.

In case somebody finds this post not so useful to create a masked input control that allows only non-negative integers (at least the suggested solutions didn't work for me either), I have found the following combination of parameter values to work for the RadMaskedNumericInput:

Mask="dddd" AutoFillNumberGroupSeparators="False" IsValidationHintVisible="False" AllowInvalidValues="True"

This allows only integers up to 9999 (if you need other limits, just change the Mask).
