Text Box has a number of features that can simplify text entry. You can change the color used to highlight the selected text by setting the Selection Highlight Color property. You can provide custom handling of the Paste event on editable text controls in your app.

It comes with a familiar, built-in context menu with support for copying and pasting text. Add(text Box); The resulting Text Box looks like this. For example, you might remove the line breaks from a multi-line address when pasting it into a single-line search box.

The WPF Application Framework (WAF) is a lightweight Framework that helps you to create well structured WPF Applications.

The text displays on the screen in a simple uniform plaintext format. Handle the Selection Changed event to do something when the user selects or de-selects text.Window_Loaded is the method which is generated for you when you double click on the WPF window in the designer. It sounds like you have retyped the method instead of just registering the event handler in the one that already exists.I'm looking to accept digits and the decimal point, but no sign.I've looked at samples using the Numeric Up Down control for Win Forms, and this sample of a Numeric Up Down custom control from Microsoft.But so far it seems like Numeric Up Down (supported by WPF or not) is not going to provide the functionality that I want.
