In WPF , the RichTextBox  control is not really like other controls. Due to its flexible nature, there is no built in way of binding a property to the content. In this case, I wanted a simple  RichTextBox  control with a binding to an HTML formatted string to be able to use the built-in formatting features of the  RichTextBox  and allow users to create simple HTML formatted content. First, doing the conversion on-the-fly proved to have major performance issues, so I ended up binding the content to a XAML string. The XAML to HTML conversion can be performed at any time. I created a UserControl with a bindable Text-property. The view contains a  RichTextBox  control. <RichTextBox x:Name="richTextBox" TextChanged="OnRichTextBoxChanged"> The source code for the user control contains the Text property and the methods to handle the binding. public static readonly DependencyProperty TextProperty = DependencyProperty.Register( "Te...

Sometimes there is a need to display a HTML formatted string in a WPF application. There are a couple of ways to do this, but the most stright forward is to use a WebBrowser control and the NavigateToString method. This approach has one big flaw, you cannot use binding to a string out of the box, but I found a great solution through Stack Overflow which adds a bindable property to the  WebBrowser  control using  NavigateToString . The following class is all that is needed to add that behavior. A new depencency property named Html is introduced to the  WebBrowser  and the proper change action is performed in the OnHtmlChanged method. public class BrowserBehavior { public static readonly DependencyProperty HtmlProperty = DependencyProperty.RegisterAttached( "Html", typeof(string), typeof(BrowserBehavior), new FrameworkPropertyMetadata(OnHtmlChanged)); [AttachedPropertyBrowsableForType(typeof(WebBrowser))] public static string GetHtml(...
