If you've got HTML content, you could use the WebBrowser control - otherwise you will have to convert the HTML to RTF to render in the RichTextBox

Use a hidden WebBrowser Control and load it with the html content you want. Then SelectAll() from the WebBrowser, Copy(), and Paste() into the richtextbox.

WebBrowser wb = new WebBrowser(); wb.Navigate("about:blank");
string url=@"http:\\....";
wb.Navigate(url);
private const int sleepTimeMiliseconds = 200;

while (wb.ReadyState != WebBrowserReadyState.Complete)
{
Thread.Sleep(sleepTimeMiliseconds);
Application.DoEvents();
}

wb.Document.ExecCommand("SelectAll", false, null);
wb.Document.ExecCommand("Copy", false, null);
richtextbox.Paste();

If you're willing to spend money, the DevExpress RTF control can be given HTML.

If you want HTMl highlighted text int he RichTextBox you can use something like this (Syntax Highlighting in Rich TextBox).
From there you can make your own highlighting (based on the html elements).

Here's also an example (An extended RichTextBox to save and load HTML lite files)

RTF encoding is different from HTML. You cannot do this straight away. Rowland has rightly suggested WebBrowser control.

If not, then you need to write your own HTML to RTF converter or find something similar.
