How to add TabControl in toolbox for VS Express 2012 for Web

I am new to Visual Studio.  I downloaded WebMatrix 3 which includes Visual Studio Express 2012 for Web.  I aim to create a Web Application Form which has tabs.  When I checked articles in Google and on YouTube, I observed that the TabControl control is included in VS 2012.  When I attempt to add this item to the toolbox, I get the following message.  "The following controls were successfully added to the the toolbox but are not enabled in the active designer.  (TabControl and TabControlArrary).  Make sure the controls to add are compatible with the current desiger and .NET Framework version".  I get a similar error message when I add the item to the WPF Components of the "Choose Toolbox Items" configuration box.  Please advice.

Give a look at the second column, the one named Namespace.

The TabControl is for Windows.Forms, which means that this control is available only for Windows applications.

The TabControlArray is for compatibility for VB6 and is useful only when converting old VB6 applications to .NET. It simulates something that existed in VB6 but is done differently in VB.NET.

The only controls that you can use in web pages are those in the System.Web.UI.WebControls namespace. There is no TabControl in there. The notion of tabs do not exist in web pages. When you see something that looks like a Tab on the internet, it is simulated in different ways, such as with clickable images that call a new page when you click on them.
