I have created an asp.net project in visual studio 2010 ultimate edition.
I can't see Standard, Data etc toolbox tabs, I can only see Telerik and HTML controls.
I tried to reset the toolbox, tried to delete C:\Users\mypcuser\AppData\Local\Microsoft\VisualStudio\10.0\*.tbd.
I also tried devenv /ResetSkipPkgs but nothing worked for me.
Please suggest a Solution thanks!
This may help you.
In the Toolbox, select the tab where you want to add the control.
Right-click the Toolbox and select Choose Items from the shortcut menu.
The Choose Toolbox Items dialog box opens. The following illustration shows the Choose Toolbox Items dialog box.
Try to right click on the Toolbox and select "Reset Toolbox"
The common controls should appear in the Dialog Editor list along with all the MFC ones that I seem to be limited to when the problem happens.
I have this happen frequently. I don't know what causes it, but this fix always works and is fine for me since I didn't customize anything.
This will help you... In Visual studio, go to view-toolbar-check standard and layout.. Then restart the visual studio and be sure on design page and check for toolbox.. Now the standard toolbox items will appear.. Thanks.
Just for the Future Viewer of this page
VS 2010 standard ToolBox cannot be viewed.
Mostly this is happen on a first run.
It solved the problem with Ctrl + Alt + X in your keyboard.
