Visual Studio 2010 Toolbox controls disabled

Question

VS 2010 Toolbox in ASP.NET application development (design mode or source) is not showing all controls (showing HTML and reporting ones), I can see all by right click (Show all) but they are greyed out or inactive.

I have used devnev.exe in VS Command line to reset, have reinstalled VS, have deleted the four hidden files in C:\Users\Ramzan\AppData\Local\Microsoft\VisualStudio\10.0 with extension .tbd, all in vain.

This thing is driving me mad. I have another machine and everything works fine there.
Any help much appreciated.

Don't know if this applies; but I had all controls in the toolbox disabled; you could see them but they were disabled - This in Visual Studio 2010. I right click on a toolbox item then reset toolbox and then they are enabled. Note that you may lose any custom controls you added.
