How to use custom font in WPF RichTextBox (SfRichTextBoxAdv) control?

In the SfRichTextBoxAdv control, you can use any custom font to render text content apart from the fonts installed on your machine.

Add the required font as a resource file in your project.

You can use the custom font by specifying the font name with its reference path and “#” as a prefix.

The following code example demonstrates how to use a custom font in the SfRichTextBoxAdv control.

XAML

<richtextboxadv:sfrichtextboxadv x:name="richTextBoxAdv" fontfamily="Assets/MyFont.ttf#MyFont">
         <richtextboxadv:documentadv>
              <richtextboxadv:documentadv.characterformat>
                  <richtextboxadv:characterformat fontfamily="Assets/MyFont.ttf#MyFont">
                  </richtextboxadv:characterformat>
              </richtextboxadv:documentadv.characterformat>
          </richtextboxadv:documentadv>
</richtextboxadv:sfrichtextboxadv>
