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 &gt; Options &gt; Windows Forms Designer &gt; General
At the bottom of the list, you'll find Toolbox &gt; 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.

Right-click on toolbar then click on "choose item" in context menu. A dialog with registered components pops up. in this dialog click "Browse" to select your assembly with the usercontrol you want to use.

PS.
This assembly should be registered before.

blocks|key|960566|text|我发现用户控件必须有一个无参数的构造函数，否则它不会出现在列表中。至少在vs2005中是这样的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|960567|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I found that the user control must have a parameterless constructor or it won't show up in the list. at least that was true in vs2005.

blocks|key|960526|text|使用VS+2010：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|960527|假设您有一个Windows.Forms项目。您可以向项目中添加一个UserControl+(比如MyControl)，并对其进行设计。现在，您希望将其添加到工具箱中。|960528|一旦项目成功构建，它就会出现在您的框架组件中。右击“工具箱”以获得上下文菜单，选择“选择项...”，然后浏览到".NET框架组件“选项卡下的控件名称(MyControl)。|960529|与使用dll相比的优点:您可以在窗体所在的同一项目中编辑控件，窗体将使用新控件生成。但是，该控件仅对此项目可用。|960530|注意:如果控件有生成错误，请在移动到包含窗体之前解决这些错误，否则设计器可能会心脏病发作。|960531|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

Using VS 2010:

Let's say you have a Windows.Forms project. You add a UserControl (say MyControl) to the project, and design it all up. Now you want to add it to your toolbox.

As soon as the project is successfully built once, it will appear in your Framework Components. Right click the Toolbox to get the context menu, select "Choose Items...", and browse to the name of your control (MyControl) under the ".NET Framework Components" tab.

Advantage over using dlls: you can edit the controls in the same project as your form, and the form will build with the new controls. However, the control will only be avilable to this project.

Note: If the control has build errors, resolve them before moving on to the containing forms, or the designer has a heart attack.

blocks|key|960821|text|在我的例子中，我看不到项目中的任何控件。只有当右键单击toolBox并选择“全部显示”时，我才能看到它们，但它们却被禁用了……|type|unstyled|depth|inlineStyleRanges|entityRanges|data|960822|将项目类型从Windows应用程序更改为ClassLibrary进行了修复。|960823|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

In my case, I couldn't see any of the controls in the project. Only when right clicking on toolBox and selecting "Show All" I saw them, but yet they were disabled...

Changing Project type from Windows application to ClassLibrary made the fix.

blocks|key|1174961|text|如果您在基控件中使用泛型，则使用基本问题。如果是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1174962|假设我们有控制权：|1174963|public+class+MyComboDropDown+:+ComboDropDownComon<MyType>

}

public+class+MyComboDropDownBase+:+ComboDropDownComon<MyType>

}|1174966|在重新生成并重置工具箱之后，它应该能够在设计器和工具箱中看到MyComboDropDown|1174967|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Basic qustion if you are using generics in your base control.
If yes:

lets say we have control:

<pre><code>public class MyComboDropDown : ComboDropDownComon&lt;MyType&gt;
{
 public MyComboDropDown() { }
}
</code></pre>

MyComboDropDown will not allow to open designer on it and will be not shown in Toolbox.
Why? Because base control is not already compiled - when MyComboDropDown is complied.
You can modify to this:

<pre><code>public class MyComboDropDown : MyComboDropDownBase
{
 public MyComboDropDown() { }
}

public class MyComboDropDownBase : ComboDropDownComon&lt;MyType&gt;
{

}
</code></pre>

Than after rebuild, and reset toolbox it should be able to see MyComboDropDown in designer and also in Toolbox

blocks|key|1174885|text|我的设计器的问题是32位与64位的问题。我可以按照Cannot+add+Controls+from+64-bit+Assemblies+to+the+Toolbox+or+Use+in+Designers+Within+the+Visual+Studio+IDE+MS知识库文章中的说明将控件添加到工具箱中。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1174886|entityMap|0|LINK|mutability|MUTABLE|url|http://support.microsoft.com/kb/963017^0|P|2Y|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

The issue with my designer was 32 vs 64 bit issue.

I just had this issue with VS 2022. There may be a quick/easy answer.
My quick and dirty user control would not appear in the toolbox (full rebuild etc.).
I quit the solutiuon and VS, reloaded all, rebuilt and it appeared and worked.

I made a usercontrol in my project, and after building project, I need to put it in my toolbox, and use it as a common control. but i can't. the <code>UserControl</code> is in my project namespace, and I tried <code>Choose Item</code> in right click menu, but I didn't find a way to add it.

How to put a UserControl into Visual Studio toolBox

我在我的项目中创建了一个用户控件，在构建项目之后，我需要将它放在我的工具箱中，并将其作为一个公共控件使用。UserControl在我的项目名称空间中，我在右击菜单中尝试了Choose Item，但我没有找到添加它的方法。
