The Extended WPF Toolkit is a collection of WPF controls, components and utilities made available outside the normal WPF Toolkit. It includes controls that are missing from the WPF Toolkit, or that have been ported over from the Silverlight Toolkit.
Controls in the Extended toolkit
RichTextBoxFormatBar
The RichTextBoxFormatBar is a contextual formatting toolbar that mimics the behavior of the Microsoft Office 2010 formatting bar. It can be attached to any Richtextbox control by using the RichTextBoxFormatBarManager. You can even create your own formatting bar and use it instead, but still have all the functionality the RichTextboxFormatBarManager provides.
ButtonSpinner
The ButtonSpinner control allows you to add button spinners to any element and then respond to the Spin event to manipulate that element. The Spin event lets the developer know which direction the buttons are spinning; SpinDirection.Increase indicates an increment, SpinDirection.Decrease indicates a decrement.
NumericUpDown
The NumericUpDown control provides a TextBox with button spinners that allow incrementing and decrementing numeric values by using the spinner buttons, keyboard up/down arrows, or mouse wheel.
BusyIndicator
BusyIndicator makes it easy to let the user know when an application is busy. Simply wrap the relevant content in an instance of the BusyIndicator control and toggle its IsBusy property to True during any long-running process.
ColorPicker
The ColorPicker is an editor that allows a user to select a custom color including support for transparency.
MessageBox
Displays a message box that has a message and that returns a result.
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 implementing the contract accordingly.
