Customize RichTextBox for Plain Text Input
This sample demonstrates how to create a custom RichTextBox implementation that allows users to apply formatting properties to longer runs of text, but restricts the RichTextBox scheme to allow only plain text input.
A real-world use for this implementation might be a lightweight code editor.
Note that the sample detects only one string as a hyperlink (www.microsoft.com). A real-world application might use a regular expression match to detect a hyperlink.
