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.
回答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:

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

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.
