.NET Information center: #381 – Loading .rtf Files Into a RichTextBox

Thursday, September 08, 2011

The RichTextBox control supports loading not only Text (.txt) files, but also Rich text (.rtf) files.

You can load a file using the Load method of the RichTextBox’s Selection property.

<RichTextBox x:Name="rtfMain" />
rtfMain.Selection.Load(new FileStream(@"D:\Spade.rtf", FileMode.Open), DataFormats.Rtf);
