I have a small application where i need to navigate to an url, I use this method to get the Frame:
public override System.Windows.UIElement GetPage(System.Windows.UIElement container)
{
XmlDocument doc = new XmlDocument();
doc.Load(Location);
string webSiteUrl = doc.SelectSingleNode("website").InnerText;
Frame newFrame = new Frame();
if (!webSiteUrl.StartsWith("http://"))
{
webSiteUrl = "http://" + webSiteUrl;
}
newFrame.Source = new Uri(webSiteUrl);
return newFrame;
}
My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing. When i attach my debugger i get this error:
System.ArgumentException was unhandled
Message="Parameter and value pair is not valid. Expected form is parameter=value."
Source="WindowsBase"

InnerException:
Anyone? Or any way to capture it and respond to it, tried a try/catch around my code, but its not caught - seems something deep inside the guts of the CLR is failing.
