Is there anyway to display a null value in the NumericUpDown control? I don't have an issue saving "null", but the control never shows anything but 0 or >0, even when it's explicity set to null. I need it to display null and integers. Thanks!
<
telerik:RadNumericUpDown x:Name="numMileage" NullValue="" Width="75" IsInteger="True" Minimum="-1" Maximum="30001" NumberDecimalDigits="0" Value="{Binding MileageRange, Mode=TwoWay, ValidatesOnExceptions=True}" Margin="0,0,10,0"></telerik:RadNumericUpDown>

You should set the NullValue property of the NumericUpDown to the needed value like this:
Hope this helps.

Thanks for responding ... but I've already tried that and it doesn't seem to work. It always shows a 0 instead of null. Any other ideas??

Hi,
You can find attached a simple example which demonstrates that RadNumericUpDown shows "null" when its value is null without a problem at our side. What is different in your case?

I have a range 0-100 for the nullable value and have no issues displaying "NULL". However I can't find a way to reset the value to "NULL" from the control. How can user define 0-100 and "NULL" from the UI?
Thanks in advance,
Denis

Hello Denis,
You should set IsEditable property of the NumericUpDown to true and then the user will be able to delete the text and thus set the value to NULL.
Hope this helps.
