WebBrowser, Styles, and DesignMode

(OP)
Hello all.

I'm creating a C# CMS for our website, and I'm trying to incorporate a WYSWIG HTML editor for a couple of screens.

I'm running into a difficulty with styles though.

In the DocumentCompleted event I am adding styles like this:

CODE

IHTMLStyleSheet sheet = doc.createStyleSheet("", 0);
sheet.addRule("body", "font-family: Calibri, Tahoma, Verdana, Helvetica, Arial;", -1);
...

As long as I don't set designMode to "On", the styles work and what is loaded appears with the styles I specified. Once I set designMode to "On", the styles are lost.

I found some documentation that seems to indicate that setting designMode to "On" reloads the contents - I figured this might be clearing the styles I set. So I set designMode to "On" before creating the styles, and as soon as it tries to create the stylesheet I get an error: "Error HRESULT E_FAIL has been returned from a call to a COM component."

Anyone have any clues on how to handle this?

Thanks.

Ok, I think I got this working.

Instead of using:

CODE

doc.designMode = "On"; //An IHTMLDocument2 reference

I am now using:

CODE

wb.Document.Body.SetAttribute("contenteditable", "true"); //wb is the WebBrowser reference

Styles are now staying set, and I can edit the page.
