Please see the following code.

private void Form1_Load(object sender, EventArgs e)
       {

           geckoWebBrowser1.Navigate("http://localhost:62343/ReportPage.html);

       }

private void Form1_Shown(object sender, EventArgs e)
       {
           var item1 = geckoWebBrowser1.Document.GetElementById("DynamicGrid");

           htmlelem = item1.InnerHtml;
       }

The problem is that when I run my project I get item1 as null in Form1_Shown.

But When I put this code under a button event like

private void buttonGetDom_Click(object sender, EventArgs e)
        {
             var item1 = geckoWebBrowser1.Document.GetElementById("DynamicGrid");

            htmlelem = item1.InnerHtml;

        }

Then I get the innerhtml. How can I Get innerhtml of this Element in Form_Shown ?

Please keep in mind that I need to access this DOM only from from Form1_Shown and I am using GeckoWebBrowser.

Can anyone help me please ?
