WPF Edit Mask

Question

What is the easiest way to specify an edit mask in WPF for a simple Text Box?

e.g. one that transforms 10000 to 10,000 as you type.

Answer 1

Short answer, there is no easy way. If you use masks quite often, I would recommend creating your own control with masking functionality. Using the MaskedTextProvider class should be fairly straightforward.

See the following for an example of a custom TextBox with masking capabilities:

Answer 2

Easiest and most straightforward way is probably just to grab the TextChanged event and do whatever processing you need.

Answer 3

Have you looked at the Xceed DataGrid Express for WPF. It is free and provides a masked text box control that will very simply do what you want.

The xceed Datagrid Express edition for WPF is no longer available.
