In this article, we’ll take a look at the Silverlight Rich Text Box control. The Rich Text Box was one of the new, and highly requested controls introduced in Silverlight 4.This article is accompanied by a Visual Studio solution, which you can find here. What do we get?
Out of the box, the Rich Text Box control looks like a simple TextBox: you get the typical TextBox look, nothing more. However, under the covers, it offers us the ability to display formatted text, paragraphs, hyperlinks or inline images – and even more than that: you can actually use the Rich Text Box to display any UIElement (so if you want a DataGrid in your Rich Text Box, that’s entirely possible). The Rich Text Box has a content property, Blocks, which is a collection of Paragraph elements (Paragraph derives from Block). These Paragraph elements can in turn contain elements that are derived from Inline, like Run (we know that one from the regular Text Box), Span, Bold, Italic, Underline, Hyperlink and the InlineUIContainer (which can contain UIElements). This image (from MSDN) offers an overview of the content model:
