Nullify the value binding on IntegerUpDown from spinner

Question

Is it possible to set the Minimum value of the IntegerUpDown (or any UpDownBase) to null?

The way I would like the control to operate is:

• Initialize as null
• Start at 0 if the user increments the spinner
• Return to null if the user decrements from 0

I tried various combinations of setting IntegerUpDown.Minimum and IntegerUpDown.DefaultValue, but the setter on the property binding seems to re-invoke with the previous value after nullifying (can update with explanation if warranted).

Answer 1

You can define nullable integer (or other variables that doesn't have the null option by default) like this:

int? IntegerUpDown = null;
if (IntegerUpDown.HasValue)
{
    int NewInt = IntegerUpDown.Value;
}
