I had already tried that. That does not work.

Hi gmcalab,

If you set ValueType="System:Int32" Minimum="-999" Maximum="999" - this will guarantee that user will be able to enter only the numbers between (-999, 999)

Regards,

Is there a way to hide the thousands seperator if I were to make the maximum of 9999? I am trying to use this so the user can enter a year....

ultraNumericEditor1.FormatString = "####";

That would probably work if that property existed for the Silverlight Control, but it doesn't look like it does....
