I am using visual studio 2015. I have my toolbox open and I checked on Show All. I unchecked this an now my entire toolbox is empty except for the General Tab (which there is nothing in). I tried resetting the toolbox but that did not fix the problem. Has anyone encountered this before? If so, what was the fix? Thanks.

What type of file do you have open in the IDE? In code files it is empty, but Razor/WebForms should have items in the toolbox. – Sam Dec 29 '15 at 17:41

1It might be because the IDE has somehow determined you are not a Seattle Seahawks fan. This happens to me sometimes, too; if you simply try a second or third time to open the Toolbox, it will eventually acquiesce (provided, as Sam says, an appropriate file is open). BTW, say hi to Rod for me. – B. Clay Shannon-B. Crow Raven Dec 29 '15 at 17:57

This issue still affects later versions of Visual Studio (e.g. VS2019), see how to fix this in my answer below. – sɐunıɔןɐqɐp Apr 28 '21 at 10:12

Try right clicking in the toolbox and select 'show all'.
You can also start /reset
From your description, it seems that your issue might be related with IDE. I suggest you to try to execute the following commands:
Devenv.exe /SafeMode
Devenv.exe /ResetSettings

This is a working solution. For those who don't know the path "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE" first you must CD to such director through CMD. then execute Type "Devenv.exe /ResetSettings" – Reagan Mar 21 '22 at 17:24
I have that problem still after using repair in VisualStudio Installer. But I found a solution here: https://thinkaboutit.be/2012/10/my-toolbox-is-empty/
The localization off that files can be in different places, for VS 2022 I found some hidden files here: C:\Users\YourUserName\AppData\Local\Microsoft\VisualStudio\17.0_dbab3d69
Deleting those files and restarting VS solved the problem.

1After trying all other existing solutions, this was the only one working in VS2022. – doterik Aug 31 '22 at 12:29

4Link only anwser: The gist is to close VS, delete the hidden "toolbox.*" items from "%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\17.0_cd024688" (adjust version) and restart VS. May need to do Reset Toolbox afterwards. – Jens Sep 09 '22 at 09:16

I just had the same thing happen to me in Visual Studio 2022 with a .NET 6 WinForms application. After updating VS 2022 to version 17.2.0, my Toolbox entries were blank when I tried to use them to drag and drop into the designer of a project I had just recently created in version 17.1.x.
I ended up fixing this by:
- Right-click the Toolbox
- Select Choose Items from the resulting context menu
- Press the Reset button in the resulting Choose Toolbox Items dialog
- Press the OK button when the reset process completed.

I had the same problem. I have tried with right click on the design windows and add " Toolbox" (SSIS Toolbox in my case). This worked for me.

In the case of an SSIS toolbox not appearing. On the top ribbon menu click on View -> Other Windows -> SSIS Toolbox, this will show the toolbox with SSIS related items.

I had a similar problem(Visual Studio 2022). None of the solutions solved my problem. Eventually my problem was solved by repairing the visual studio.
Go to Start >> All Programs >> “Visual Studio 2022” >> “Visual Studio Installer”. Now, click Visual Studio Installer. After clicking repair options progress options open. The repair will take some minutes to complete.
I don't know why this bug exists, but I fixed mine using the steps below:
- Right click on toolbox -> Show All -> Check.
- Wait it to load the controls, then click OK
- Rigth click on Toolbox and select -> Show All -> Uncheck

I encountered the same problem and solved it by:
- closing the toggled/opened toolbox
- opening any windows form [designer]
- re-opening the toolbox
toolbox components will be reloaded again

This is an old question but I could fix it easily by just stopping the program running.
If you run your app to test it the toolbox will be empty until you stop the debugger!

In my case, I had opened with ctrl+alt+x. I noticed in the newer versions of VS, there is some confused crossover of toolboxes. In my case, it opened the SSRS toolbox, which was not applicable to my SSIS file.
Closed that, right-clicked in design area, and chose SSIS Toolbox. This opened a toolbox called "SSIS Toolbox" rather than just "Toolbox". All fixed.
In Visual Studio 2019 you can just right click the dark area inside the toolbox and select "Reset Toolbox".
This will remove custom-added controls or any other auto-detected control, and you will be left only with the standard controls.
The issue should be fixed without completely reseting Visual Studio's settings.
