The content of this control is defined by its property Document, see http://msdn.microsoft.com/en-us/library/system.windows.controls.richtextbox.document.aspx[^].

So, to store or load the document, you need to work with this property of the type System.Windows.Documents.FlowDocument, http://msdn.microsoft.com/en-us/library/system.windows.documents.flowdocument.aspx[^].

Through this class and property, you can manipulate the document, in particular, persist it. The manipulation of the data depends on DataTemplate you use, see http://msdn.microsoft.com/en-us/library/system.windows.datatemplate.aspx[^].

To store and load the document, you can use the class TextRange which you can get from your instance of RichTextBox. For a code sample, see: http://msdn.microsoft.com/en-us/library/aa970779.aspx#save_load_and_print_richtextbox_content[^].
