Popup window webbrowser control

I am using a webbrowser control to get some information from a website. It has a detail link, which when clicked, opens a popup window and shows the details in the webbrowser.

How can I do these if click the link in webbrowser control (by program) open another window and showing execution error.

But in explorer it is working. And I noticed that detail link works only if I open the main page in Internet Explorer, otherwise if I call the detail URL directly from Internet Explorer, it also gives me the same error.

this is dynamic version. it doesnt require statically bind com interop which is always problem in future versions of windows.

    public partial class Form10 : Form
{
    public Form10()
    {
        InitializeComponent();
        webBrowser1.Navigate("about:blank");
        dynamic ax = this.webBrowser1.ActiveXInstance;
        ax.NewWindow += new NewWindowDelegate(this.OnNewWindow);
        this.webBrowser1.Navigate("http://google.com");
    }
    private delegate void NewWindowDelegate(string URL, int Flags, string TargetFrameName, ref object PostData, string Headers, ref bool Processed);
    private void OnNewWindow(string URL, int Flags, string TargetFrameName, ref object PostData, string Headers, ref bool Processed)
    {
        Processed = true;
        //your own logic
    }
}

Refine to Middas answer...

  • add COM reference Microsoft Internet Controls.
  • use Middas Code.
  • in form_Load define your Uri and all your pop up will directly change your winform WebBrowser.

I recently ran across a very similar situation. In my case, the popup browser didn't share the session of the embedded browser. What I had to do was capture the NewWindow event and cancel it, then send the intended URL to the embedded browser. I needed to use the ActiveX browser instance because it gives you the URL that was attempting to launch. Here is my code:

You will need to add the Microsoft Internet Controls COM reference to your project for this to work.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        // this assumes that you've added an instance of WebBrowser and named it webBrowser to your form
        SHDocVw.WebBrowser_V1 axBrowser = (SHDocVw.WebBrowser_V1)webBrowser.ActiveXInstance;

        // listen for new windows
        axBrowser.NewWindow += axBrowser_NewWindow;
    }

    void axBrowser_NewWindow(string URL, int Flags, string TargetFrameName, ref object PostData, string Headers, ref bool Processed)
    {
        // cancel the PopUp event
        Processed = true;

        // send the popup URL to the WebBrowser control
        webBrowser.Navigate(URL);
    }
}
