I've managed to successfully implement this custom TabControl project. I'm Building this TabControl project as a .dll file so I can drag it into my other project's toolbox and view the custom control in the designer but when I wanted to change something in the this custom TabControl project, when I rebuild the .dll file and drag it in the toolbox again, it doesn't update the existing custom controls in the designer.
When I ctrl+m1 the variables in the custom control in use, it links to read-only metadata.
Do I need to remove all the custom controls first whenever I make a change or is there a way to "update" existing custom toolbox items that are already in the designer?
I tested this issue in vs2019 and vs2022, and it worked perfectly.
When the dll is rebuilt, it does not need to be reloaded into the toolbox.
If the program page that depends on the dll is not updated, just rebuild it.
My test environment is .Net Framework 4.8.
If you have any questions about this, please let me know and I will continue to follow up.

I created a new C# WPF app project in visual studio 2017 and added a user control to the project. Now when I try to add that user control to my main window it doesnt show up in the toolbox.
Ive checked the AutoToolboxPopulate property and it is set to true and Ive rebuilt. Ive tried closing and opening the project and Visual Studio.
What do I need to do to get my controls to show up in the toolbox?
You can try to add it to the toolbox manually
In the toolbox, select the WPF Components. At this time, click Browse, find the dll, add it, and click OK.
I accidentally made a normal user control instead of a WPF user control.
I have Class library (chart control) which was created in Visual Studio 2005 and I was going to use it in a new project (VS2010).
I clicked on Choose Items... from the toolbox, selected .NET componentes and Browse for the .dll file. The chart control was normally placed in the toolbox list.
The problem is that I want to modify a specific function from the char control.
I opened the original project in VS2005 and changed the function as well.
But now it seems that the VS2010 project cannot identify these changes.
I've already deleted the control from the toolbox list and reloaded again in the same way but it seems that it loads the old dll again.
It's strange because when I rebuild the chart control project, I see that the .dll file in Release path updates its written date. I've tried to copy this dll to another path and then load this new dll from the VS2010 but still it loads the old version. Already restarted the VS2010 without success.
How is it possible that the VS2005 rebuilds the .dll file and the VS2010 still can load the old version of it?
EDIT: thanks to #Gilchrist: just updating the control in the toolbox does not update the reference. To solve it I had to remove it from the toolbox, remove the project reference and then add again in the toolbox (which creates the new reference link).
I have looked everywhere and cannot find a solution. My problem has the following elements:
I have a Visual Studio Solution (Visual Studio 2013) with several projects.
One project ("Control Project") has several user controls I built.
Other projects ("Other Control Projects") contain various open source controls.
Another project (the "Problem Project") references the Control Project and the Other Control Projects.
The Visual Designer toolbox shows the Other Control Project controls perfectly in my Problem Project.
The Visual Designer fails to show the Control Project controls in my Problem Project.
I have tried:
1. Making sure the option to auto-populate the toolbox is checked.
2. Rebuilding the solution
3. Resetting the toolbox
4. Ensuring the access modifiers for the controls are Public.
If I "Choose Items", I can add the Control Project controls to the Problem Project by selected the .exe but this seems like a hack and also has caused other problems that are difficult to define.
Anybody have any clues on what may be wrong with either my Problem Project or my Control Project?
That answer might be a bit late but I recently had the same Problem.
For me it was a Problem with missing DLLs.
I have a nearly simular Soloution like you.
A Library providing selfmade UserControls
Another project ("Problem Project") that references the Control Library
The problem occurred when I recently switched from VS2008 to VS2013 and from .NET Framework 3.5 to .NET Framework 4.5. The cause of the Problem for me seems to be with Crystal Reports references. In my Library project I have a Class that inherits from CrystalDecisions.CrystalReports.Engine.ReportClass. This Class I provide as a control in the Toolbox. When I open the Library Project itself (not as a Subproject) and open a Form to load the Toolbox I got the following Error: Failed to create ToolboxItem of type: CrystalDecisions.VSDesigner.ReportToolboxItem, CrystalDecsions.VSDesigner.
After I knew this I found out, that I have to copy some Librarys, in my case
CrystalDecisions.CrystalReports.Engine.dll
CrystalDecisions.Shared.dll
CrystalDecisions.VSDesigner
to C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE (found it here:Can't add project controls to the Visual Studio Toolbox)
To me it seems like VS Toolbox starts to create the Controls and gets an Error at one of them and stops to fill the Toolbox. In my case the problem might be, that I reference old CR Librarys (v12.x) which work with CLR 2.0 and .NET Framework 2.0 - 3.5 and I compile my project with .NET Framework 4.5 which works with CLR 4.0. It looks like the old Librarys are not supported in .NET 4.x. If I use this Workaround the Toolbox works fine for me.

btw. sorry for the patchy english ;-)
I'm using Visual Studio 2005 for a project I'm working on right now. I've created a new, custom control that inherits from 'UserControl'. Now I need to add that control to another Windows Form within the same project. I thought that the IDE would place this custom control into the Toolbox (as I know it's done in the past when I was using Visual Studio 2008), however, it did not. Now, I'm unsure how to get the control added to my form correctly and/or how to make it show up as it should in the Toolbox. The "Auto Toolbox Populate" option under Tools is set to 'True', so I really don't know what else needs to happen at this point. The help of anyone who's had any experience with this would be greately appreciated. Thanks a lot!
You may first build your custom control and create a dll. Then,
Right-click on the Toolbox panel -> Select 'Choose Items' -> Go to '.NET framework components' tab in the 'Choose Toolbox Items' dialog box that appears - > Browse to the dll of your custom user control -> Click OK.
Now the user control will be displaying in your tool box.
Hope this helps...
Try this
Open Solution
Build project
Open your form
Reset the toolbox
Drag the user control from solution explorer to the toolbox
Close the toolbox and all open documents
Open toolbox then the form
User control should appear
worked for me.
I want use the Scintilla controls and the RadControls for Winforms, but I do not know how to incorporate the files. They are in .dll format? How do I use the controls if they are in .dll format?

Right click the project, click Add Reference, go to Browse tab, find them and add them.
Generally you would add them to the project you want to use them in, then add a reference, and then use them like any other dll.
For installing into the GAC, see this.
In the winforms toolbox, right click and "Choose Items...", then click the browse button and find the dll. Then go through the list of controls, and check the controls that you've added (usually it will do this step for you).
This knowledge base article on the Telerik website explains how to manually add the controls to the toolbox in Visual Studio.
