We are very excited with the announcement of our Q2 Beta release of RadControls for Silverlight 4.One of the most important new announcements is the new version of RadRichTextBox. The control went a long way since its CTP version and now we are eager to show you some of the new features we worked hard on during the last couple of months.

New Document Formats

First of all we will present the newly added import/export support for Html and Docx formats, which was among the most demanded features, because its heavy use for many business-oriented scenarios. Take a look at the screenshots below to see how the exported document looks in RadRichTextBox, MS Word (in docx format) and Internet Explorer (in html format):

The next very important addition is the introduction of two options for printing the content in RadRichTextBox. Now you can choose between the native printing support in Silverlight 4 or print the content as an Html document using the browser printing capabilities.

Enhancements in Document Model

  • We received a lot of requests for Inline images, and now this feature is also a fact. Copy/paste and resizing are also available:

  • Another important feature - support for hyperlinks. Here is the dialog box used in the demo for inserting hyperlinks:

    … and the result is:

  • We empowered RadRichTextBox with predefined page sizes, margins and paragraph indents. All are easily accessible trough code as well:

  • The control now offers a wide range of underline styles:

  • Line and Page-breaks support:
