Question

.Net WebBrowser.DocumentText Isn't Changing!

Answer 1

+2 A:

Try the following:

browser.Navigate("about:blank")
HtmlDocument doc = this.webBrowser1.Document
doc.Write(String.Empty)
browser.DocumentText = _emailHTML

I've found that the WebBrowser control usually needs to be initialized to about:blank anyway. The same needs to be done between navigates to different types of content (like text/xml to text/html) because the renderer is different (mshtml for text/html, something else for text/xml).

I appreciate the help. Turns out I was able to get it withbrowser.Document.OpenNew(True)You're right - I needed to initialize it.

Answer 2

A:

Just spotted this in some of our old code.

_webBrowser.DocumentText = builder.WriteToString( ... );

Application.DoEvents();

Apparently a DoEvents also kicks the browser into rendering
