Import and Export in WPF RichTextBoxAdv

5 May 20214 minutes to read

This feature lets you use several file formats, namely .doc, .docx, .html, .xaml, and .txt, inside the RichTextBoxAdv control. Using any one format allows the use of the other formats.

 HTML Import/Export

The HTML import feature allows the user to import an .html file into the RichTextBoxAdv. It renders the HTML tags like a browser and displays the text in the format of RichTextBoxAdv’s content model. The HTML export feature actually exposes the RichTextBoxAdv’s document as an .html file. The following methods clearly show this use case.

  • C#
    •      
 DocumentAdv doucment = HTMLImporting.ConvertToDocumentAdv(stream);  
 DocumentAdv document = HTMLImporting.ConvertToDocumentAdv(htmlstring);

      
string html = HTMLExporting.ConvertToHtml(RichTextBox.Document, stream);
