Getting ASP.NET page values from Silverlight

There was a need to obtain values from the ASP.NET page to Silverlight application.

This is the function that can get the value.

private string GetHtmlElementValue(string htmlElementId)

{
   string togoElementValue = "";
   HtmlDocument doc = HtmlPage.Document;
   if (doc == null)
   {
     MessageBox.Show("Html Document is null.","Error", MessageBoxButton.OK);
      return togoElementValue;
   }
   HtmlElement elm = doc.GetElementById(htmlElementId);
   if (elm == null)
   {
     MessageBox.Show("Html Element " + htmlElementId + " is null.", "Error", MessageBoxButton.OK);
     return togoElementValue;
   }
     togoElementValue = elm.GetAttribute("value");
     return togoElementValue;
}

This is how the function should be called.

GetHtmlElementValue("AuthenticationTypeField");

This will come in handy when we need to pass the information from ASP.NET page to Silverlight Application.

Hope this helps.
