Problem using WebBrowser control as editor

Question

I am currently working on a project where I am using a WebBrowser control as an editor. I have design mode turned on and it seems to be working. The issue im having is when I try to save the Document and load another it pops up the "This document has been modified." message. What I am trying to do is as simple as this

if (frontPage)
{
    frontPage = false;
    frontContent = webEditor.DocumentText;
    webEditor.DocumentText = backContent;
}
else
{
    frontPage = true;
    backContent = webEditor.DocumentText;
    webEditor.DocumentText = frontContent;
}

Like I said everytime I enter some text and run this code it just pops up a message saying its been modified and asks if I want to save. How can I get around this?

C# does not have a web browser control. Did you mean the WinForms WebBrowser Control? — John Saunders, May 03 '10 at 21:43

You should create the following function:

void ChangeAllowWebBrowserDrop() { webBrowser.AllowWebBrowserDrop = !webBrowser.AllowWebBrowserDrop; }

It should be called every time before you change DocumentText.

I have solved this problem so:

browser.Document.Write(string.Empty);  
browser.DocumentText="Your html code";

This is from this link: http://social.msdn.microsoft.com/Forums/vstudio/en-US/3a9c1965-8559-4972-95e1-da0e86cf87bb/webbrowser-strange-problem

You could set

BodyHtml.

Like this:

string newHTMLString="some html";
webBrowser1.Document.Body.InnerHtml = newHTMLString;

Worked for me .

better solution is to write empty string before you actually assign your html code: WebBrowser1.Document.Write(string.Empty);
WebBrowser1.DocumentText = "your code";

Try this webEditor.ScriptErrorsSuppressed = true;

Make sure you have disabled Script Debugging in IE in case you've turned it on.

The way Windows Forms load a document stream (used by the DocumentText property) is to navigate away to about:blank, which triggers the document modified message, then load the stream in its DocumentComplete event handler.

Since you already have a document, you can skip the navigation and load the stream into the existing document directly via its IPersistStreamInit interface like Windows Forms does in its DocumentComplete event handler.
