Usercontrols don't seem to show up in any of my VS2005 projects' toolboxes anymore. They used to, but I don't kow what happened. This is what I have been trying to get usercontrols into the toolbox:

Create a new C# windows application
Add UserControl named UserControl1 (it is in the root of the porect, not in a folder)
compile

I have checked under every single tab in the toolbox, including "All Windows Forms" but UserControl1 doesn't show. I've also tried closing and reopening the toolbox but that doesn't help.

I have seen this http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=53820&SiteID=1
but I dont have a tab called "[ProjectName] Components." is that the problem?

Does it work if you do this:

Create a new C# Windows Application in a new solution (don't use a solution folder)

Add a user control

Build

Open Form1 in the designer.

If this does not work, can you check your options at Tools->Options->WindowsForms->AutoToolboxPopulate?

Another thing you can try is to reset your toolbox (right click and choose "reset toolbox"). There might be some old tabs that are intefering with the feature.

Oi, the same thing happened to me today and I cannot get it fixed! WTF ?

Tried "Cleaning" the solution, even closed Visual Studio and manually cleared all the Bin and Obj folders, but nada;nothing;zulch!

Anyone have any ideas ?

Thank you very much,

Tools->Options->WindowsForms->AutoToolboxPopulate was the problem. I'm not sure how it was toggled off since I didn't even know about that option.
