For a MaskedTextBox, it is OnValidation.

This difference burns me every time, because to get binding working right, you have to change it to OnPropertyChanged, at least as far as I can tell.

Not sure what the implications for having the mask validated would be in doing this change...I have to assume there was some reason for the difference to begin with.

Not a biggy, but I know I'm not the first one to be confused by this.

Thanks!
