Extended WPF Toolkit – New RichTextBox Control

There has been a new control added to the Extended WPF Toolkit project on CodePlex called the RichTextBox.

The RichTextBox extends the System.Windows.Control.RichTextBox control that represents a rich editing control which operates on FlowDocument objects. The RichTextBox control has a Text dependency property which allows a user to data bind content to the RichTextBox.Document property. The RichTextBox control introduces the concept of Text Formatters. Text Formatters allows a user to format the content of the RichTextBox control into any format of their choice. Three Text Formatters are included; PlainTextFormatter, RtfFormatter, and a XamlFormatter. The RtfFormatter is the default Text Formatter. A user can create their own custom Text Formatter by creating a class that inherits from ITextFormatter and implimenting the contract accordlingly.

Usage

When data binding to the Text property, you must use the Text Formatter that matches the format of the underlying data. If your data is in RTF you must use the RTF formatter. If your data is in plain text, you must use the PlainTextFormatter.
