c# - Visual Studio 2010 toolbox controls disabled or inactive

Question

I am trying to fix this from last two 2 or 3 days but failed. VS 2010 toolbox in asp 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. Have used devnev.exe in VS command line to reset , have reinstalled VS, have deleted the four hidden files in C:UsersRamzanAppDataLocalMicrosoftVisualStudio10.0 with extension .tbd , all in vain.

This thing driving me mad. I have another machine and everything works fine. please help me out, i really did everything possible

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.
