Hi David Brenchley,
The masked controls are designed to behave like a normal TextBox but not in all cases.
For example, numeric values should be always right aligned and text values should be left aligned. In contrast to the TextBox or the Excel's cell, the text is always left aligned. The masked controls really focus on the ability to control the user's input as much as possible. You can specify the length of the value, the input characters, formatting in great details.
I have attached a small project with a sample configuration for the numeric mask. We would appreciate if you could give us your feedback in what exactly is not intuitive to you or your users. We would take it into consideration in the future development of these controls.
