I agree that my implementation is not correct, you right. Extended WPF Toolkit requires more elegant/smart decision. Using Text property it is bad idea. Thanks for comment and useful library!

I will have to take time to think about this one. I am not sure this is something the NumericUpDown control should handle. The NumericUpDown control is used to increment/decrement numeric values, not null values. Also, if implementated I would not change
the way in which a user used the control in XAML. The user should always bind to the Value property, never the Text. Also, the reason decimal values were there is because a user can change the ValueType of the Value to any other numeric data type including
Decimal, by setting the ValueType property. So where ever you see Decimal, should stay Decimal. If you are going to support null values you wouldn't want to set the value to NaN, it should just be null.
