I've Been struggling with this for over 5 hours now

Example:

 <div id='xx'>content</div>

How can i access Content of that div via GetHtmlElementById or any other solution based on "Id"

i tried 

GeckoElement el = browser.Document.GetElementById("xx");
MessageBox.Show(el.TextContent);

and im getting NullRefferenceException (Object reference not set to an instance of an object.)

Other example :Navigating to google.co.uk 

browser.DocumentCompleted += delegate { 
                MessageBox.Show(browser.DomDocument.GetElementById("gbqfsa").TextContent);

            };

MessageBox should show me "Google Search" but no luck

System.NullReferenceException was unhandled by user code
Message=Object reference not set to an instance of an object.

            GeckoHtmlElement ele;
            ele = geckoWebBrowser1.Document.GetHtmlElementById("myData");
            MessageBox.Show(ele.GetAttribute("Value"));

This works for me.

  • I was searching for this solution for few weeks - thanks a lot. But maybe You can tell me if this "Value" attribute is "InnerHtml" of ID div ? – Bri.H. Oct 18 '16 at 10:03
