Toolbox disappeared after installing charts for ASP.NET in Visual Studio

Downloaded charts from this site. I installed 1,2 and 3 parts. Now the toolbox does not show any control. There is an additinal tab that appears next to toolbox and it has no name. How to fix it? enter image description here

Solution

Right click on the toolbox area, choose reset. Restart Visual studio. Start a new project. The controls appears.
