Update Tab's Name in C# Web Browser

Question

I'm working on a Web browser in Visual Studio 2010, but I can't update the tab's name to the website's name. For example, when you visit a website like CNN.Com, I want the tab to also say, "cnn.com". The project isn't using the default WebBrowser form, by the way. Please explain it in the simplest way possible since I'm new to C#(Just moved from C++ and Java) so I'm not familiar with working with Windows forms. Thanks. Any help is appreciated.

Here's an image of the problem: http://postimage.org/image/5ym4yx0pt/

        tabControl1.TabPages.Add("Tab");//problem
        tabControl1.SelectTab(i - 1);
        Browse.Name = "Lithium Browser";
        Browse.Dock = DockStyle.Fill;
        tabControl1.SelectedTab.Controls.Add(Browse);
        i++;
        ((WebBrowser)tabControl1.SelectedTab.Controls[0]).Navigate("www.google.com");
    }

Assuming WebBrowser is the built-in WebBrowser, you can fire the OnDocumentTitleChanged event to change the tab text every time the WebBrowser document title is changed.

to do this, in the form load event, after declaring browse, start typing browse.DocumentTitleChanged += and a tooltip should come up saying 'tab to insert this code' or something along those lines. Just tab twice and Visual Studio will insert a new method for you, with a throw new NotImplementedException(); line. Delete that line and replace it with the code changing your tab's text to the browser's DocumentTitle.

If you need any more information, I suggest you check the documentation: http://msdn.microsoft.com/en-us/library/system.windows.forms.webbrowser.aspx

Though I am confident that using events is the best solution. Events are designed to execute upon certain significant programming 'events' happening, and changing a webpage is one example of such an event. (Events are roughly C#'s equivalent of C++'s function pointers if that helps your understanding at all. Though they are more akin to a std::vector of function pointers.)

Set the HTML title tag for the page text contained within the two tags will show up in the tab that the web page is displayed in.

See the following for more about setting the title in the code behind How to use Eval in codebehind to set Page.Title
