How to Put a Usercontrol into Visual Studio Toolbox

How to put a UserControl into Visual Studio toolBox

I had problems getting them to add automatically to the toolbox as in VS2008/2005.

There's actually an option to stop the toolbox auto-populating!

Go to Tools > Options > Windows Forms Designer > General

At the bottom of the list, you'll find Toolbox > AutoToolboxPopulate which on a fresh install defaults to False. Set it true and then rebuild your solution.

Hey presto, the user controls in your solution should be automatically added to the toolbox.

You might have to reload the solution as well.

How do I add my new User Control to the Toolbox or a new Winform?

Assuming I understand what you mean:

1. If your UserControl is in a library you can add this to you Toolbox using

   Toolbox -> right click -> Choose Items -> Browse

   Select your assembly with the UserControl.

2. If the UserControl is part of your project you only need to build the entire solution. After that, your UserControl should appear in the toolbox.

In general, it is not possible to add a Control from Solution Explorer, only from the Toolbox.

How to add a UserControl which is in a Folder in Project to ToolBox

User controls which are in the current project will be added to toolbox automatically after a successful build and you don't need to perform additional tasks to do so.

Such problems which the toolbox not being populated with new user controls, are usually build error or designer errors. To solve the problem you can perform these tasks:

• Close Visual studio

• Delete Visual Studio designer cached files. To do so, go to below path and delete all folders:

  %userprofile%\appdata\local\Microsoft\VisualStudio\11.0\Proj‌​ectAssemblies 
  

• Delete bin and obj folder of your projects.

• Open Visual Studio again and build solution.

User control missing from Toolbox

No fix found.

I started a new project and copied the User Control in first and built the solution. After that I was able to see FocusControl under 'ProjectRaven Components' at the top of my toolbox. I simply copy/pasted the controls and code back from the old project to the new one. It seems to be working.

Remember to change the namespaces if you made a new project with a new project name.

Can I add a custom UserControl library to the Visual Studio toolbox if it references another assembly?

It seems it is possible to add UserControls to the Visual Studio toolbox if their assembly depends on another assembly. In the 'Choose Toolbox Items' -> Browse dialog, you need to multi-select the dll containing the user controls AND the dll it depends on, then click 'Open'.

Adding Custom UserControl to Visual Studio 2005's Toolbox

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...

Make WinForms UserControl appear in Toolbox for WPF Visual C# project?

Not the most straightforward solution, but you could create a wrapper containing a WindowsFormsHost object. I can't document it, but I suppose that you can't natively combine the two control types because of the airspace problem.

EDIT: I've created a WPF Application solution, then added a WPF User Control Library project to the solution. Afterwards, I've referenced WindowsFormsIntegration in the latter project, added a WindowsFormsHost container, set a System.Windows.Forms.TextBox as its child. After compiling it, in the ToolBox there was a new element, containing the newly created control. I can drag it from there to "All WPF Controls" or select the compiled assembly from the Choose Items dialog.

How to drag a UserControl into the Toolbox?

You don't. Just drag the UserControl from the solution explorer onto the design surface. No need to add it into the toolbox first.

Here is a relevant article in the asp.net forum.

How do I add a user control to toolbox?

If your component is within the project, you can have them automatically added to the toolbox. Go to: Tools -> Options -> Windows Forms Designer and enable the "AutoToolboxPopulate" option.

If it's in a separate solution, you can build the control library, and drag and drop on the toolbox to add the components.
