Hello guys,

this is my first post so I wanted to say, what a great community.
I have a problem with a WebBrowserControl when opening a pdf with parameters.

I call it like this:

var url = new Uri("C:\\tmp\\MyPdf.pdf#navpanes=0&toolbar=0");
WebBrowserControl1.Navigate(url);

It is working, without any problems until I use the same command again.
The WebBrowserControl gets gray because of the adobe acrobat background.

I tried to reset the page with WebBrowserControl1.Navigate(about:blank) before reopening again, but this was also not working.

I have an solution.
try this.
First add an panel for imbeding the webbrowser it's in.
Then use this method for open the page

C#

void OpenWebPage(ref WebBrowser _webBrowser,string _link)
       {
           if (!_webBrowser.IsDisposed)
               _webBrowser.Dispose();

           _webBrowser = new WebBrowser();
           panel2.Controls.Add(_webBrowser);
           _webBrowser.Dock = DockStyle.Fill;
           _webBrowser.Show();
           _webBrowser.Navigate(_link);
       }

click like this.

C#

private void button1_Click(object sender, EventArgs e)
        {
            OpenWebPage(ref webBrwser, "C:\\tmp\\typescript.pdf#navpanes=0&toolbar=0");
        }
