Convert HTML to WPF RichTextBox in C# and .NET


Modern software often requires the display and editing of complex text data, which includes formatting, images, tables, and other elements. One of the most common formats for storing and exchanging text format is HTML. In applications on the platform .NET when using the Windows Presentation Foundation (WPF), the RichTextBox component is widely used, which is designed to display and edit formatted text.

Sometimes the task arises to convert HTML content to a format that is supported by RichTextBox, for example, RTF or FlowDocument. In this case, the task is the opposite: to convert HTML into a format that can be uploaded to 'RichTextBox'. The solution is to use third-party libraries, namely SautinSoft HTML to RTF .Net, which allows you to convert HTML to RTF, and then display the result inside WPF.

Advantages:

  • Versatility of content display. You can display dynamic HTML-generated or externally received content, for example, from web pages, messages or documents, directly inside desktop applications.
  • Editing and Formatting. After conversion, the resulting RTF or FlowDocument can be edited and formatted inside the 'RichTextBox', creating a more interactive user interface.
  • Integration with web content. In some business applications, it is important to show HTML content and at the same time give the user the opportunity to edit or save it after changes.

This code is useful in a wide variety of scenarios:

  • Blogs and content management systems. For displaying HTML articles inside desktop applications, such as editors or readers.
  • Document editors. When you need to import HTML formatting into an editor based on 'RichTextBox'.
  • Customer support platforms and chatbots. To display beautifully formatted messages, products or instructions received in HTML.
  • Educational applications and presentations. For displaying complex text data with formatting, images, and links.
