I am using a UltraNumericEditor for representing telephone numbers.

I am using a MaskInput  #-###-###-#### for a 11 digit number. The problem is that If I just wanted

to enter the number without entering areacode or the first digit, in other words I am entering this

_-___-445-4343 and than try to tab out. It does not let me tab out unless I either blank out the whole

control or I enter in the first digit and area code.

I have set CausesValidation to false, Nullable to True, AlwaysInEditMode to False

Is there anything else I should be doing.

I have also tried using UltraMaskEdit control for telephone numbers and it behaves in the same manner
