Visual Studio automatically manages assembly referencing, so you can focus on selecting and dragging controls onto your designer for seamless integration. You can add custom controls to the Visual Studio toolbox so that they can be used easily in Visual Studio projects just by dragging them in the designer. To do so, you don’t have to add the assembly reference manually. The reference is automatically added to the Visual Studio reference manager. ## Add custom controls to Visual Studio toolbox To add custom controls to Visual Studio, create a new project (ASP.NET Web Forms, WPF, or WinForms) and open the designer. The toolbox items will only be visible in the designer window. If the toolbox is not visible, click the **View** menu, and then select the ** Toolbox** option. Now, the toolbox will be displayed. Then: 1. To create a new tab for the custom controls, right-click anywhere in the Toolbox window, select **Add Tab**, and then provide a name for the new tab. 2. Then, right-click anywhere inside the new tab, and then select **Choose Items**. The Choose Toolbox Items dialog box will be displayed.![Showing the Choose Toolbox Items dialog](https://www.syncfusion.com/blogs/wp-content/uploads/2019/11/Showing-the-Choose-Toolbox-Items-dialog.png) 3. This dialog box shows a list of controls present in GAC that can be added to the toolbox. The check box in the selected state means those items will already be present in the toolbox. 4. Select the custom controls from the available list, and then click **OK**. 5. The selected controls will now be displayed in Visual Studio toolbox.![Displaying the selected controls in Visual Studio toolbox](https://www.syncfusion.com/blogs/wp-content/uploads/2019/11/Displaying-the-selected-controls-in-Visual-Studio-toolbox.png) 6. Alternatively, you can also add tools by navigating to the assembly location, and dragging the assembly directly to the newly created tab. 7. Once the controls are added, you can drag the control to the designer from the Visual Studio Toolbox and start using it. The assembly reference will automatically be added in the reference manager.![Dragging the custom control to the designer](https://www.syncfusion.com/blogs/wp-content/uploads/2019/11/Dragging-the-custom-control-to-the-designer.png) To configure Syncfusion’s custom controls in your Visual Studio toolbox, refer to this [documentation](https://help.syncfusion.com/common/essential-studio/utilities#toolbox-configuration) . ## Conclusion In this blog post, we’ve seen how to add custom controls to the Visual Studio toolbox.
