Normally the Visual Studio
is slow while loading the toolbox controls only the first time it's started after the controls installation.
If the Toolbox is loading slowly every time then you can try to fix it by resetting the Toolbox. Follow these steps:
- Close all Visual Studio instances.
- Open Windows Explorer and navigate to "%localappdata%\Microsoft\VisualStudio\10.0\".
- Make sure that the option 'Show hidden files...' is selected in the Windows Explorer options.
- Delete all *.tbd files.
- Start Visual Studio 2010 and use the Toolbox Configurator wizard to set the required controls version.
The first time the Toolbox is opened after the reset, it's expected to be slow again because it needs to repopulate the controls but it should not happen after that.
If you still want to remove the controls from the Visual Studio Toolbox
you can either delete the tab they are all in by right clicking and "Delete Tab"
or just right click on the item itself and "Delete"
