Browser control NavigateToString display HTML code instead of rendering page

I am developing a browser app using Windows Phone 8 browser control.

The app download an external webpage using WebClient into a string in the background. Then the browser navigate to the content using

webBrowser.NavigateToString(str);

However, instead of rendering the page, the browser shows the HTML code. I thought since no changes were made to the string, NavigateToString should handle it seamlessly. Or perhaps I am missing something.

So how do I display the HTML page instead of its code?

EDIT

Here's some of my code

        webClient = new WebClient();
        webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadStringCompleted);
        webClient.DownloadStringAsync(new Uri(uri));



    private  void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
         PageString = e.Result;
    }

    ...

     webBrowser.NavigateToString(PageString);

Another Way:

        wb.Navigate("");
        do
        {
            Application.DoEvents();
        } while ((wb.ReadyState != WebBrowserReadyState.Complete));
        wb.Document.Body.InnerHtml = "Html";

When you use DownloadStringAsync, it also downloads the DOCTYPE declaration. You can remove this and start your code with the <html> block as NavigateToString doesn't seem to like the <!DOCTYPE HTML> declaration.

webClient = new WebClient();
webClient.DownloadStringCompleted += webClient_DownloadStringCompleted;
webClient.DownloadStringAsync(new Uri(uri));

void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    //remove "<!DOCTYPE HTML>"
    PageString = e.Result.Replace("<!DOCTYPE HTML>","").Trim();        
}

webBrowser.NavigateToString(PageString);

Documentation for WebBrowser.NavigateToString says:

If the text parameter is not in valid HTML format, it will be displayed as plain text.

Can you check if str is in valid HTML format?

private  void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
     PageString = e.Result;
     webBrowser.NavigateToString(PageString); 
}
