Answer 1

What I can comprehend from your post and comments, is that you have six LinkLabels (named linkLabel1 to linkLabel6). When the user clicks any of the links, your WebKitBrowser control has to navigate to the URL (which is the text of the linklabel) and when the document is loaded, it has to take automatically a screenshot.

Now, as you would like to do all the same with the different linklabels, you should only create one event handler to handle the clicks of the different linklabels. You can just attach the _LinkClicked() event to any of the linklabels. You’ll also have to define in your class some private field that will contain the LinkLabel that was last clicked on.

private LinkLabel _lastClickedLinkLabel = null;

private void linkLabelX_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    // Cast the sender to a LinkLabel object as you want to know which LinkLabel
    // was clicked on
    var senderLinkLabel = sender as LinkLabel;
    if (senderLinkLabel != null)
    {
        ((WebKitBrowser)tabControl1.SelectedTab.Controls[0]).Navigate(senderLinkLabel.Text);
        _lastClickedLinkLabel = senderLinkLabel;
    }
}

Now as you want to take the screenshot after the page is loaded, you’ll have to create the DocumentCompleted event. (Don’t forget to attach it to your tabControl!)

private void tabControl1_DocumentCompleted(Object sender, WebBrowserDocumentCompletedEventArgs e)
{
    // Save the screenshot
    // you might want to determine the filename dynamically, otherwise the file will be overwritten
    ((WebKitBrowser)tabControl1.SelectedTab.Controls[0]).PageScreenshot.Save("thumb1.png", ImageFormat.Png);

    if (_lastClickedLinkLabel != null)
    {
        // Do something here based upon the _lastClickedLinkLabel
    }
}

Note that I don’t have actual experience with that exact control, I just used a search engine to find all information.
