ComponentOne controls are automatically added to Visual Studio Toolbox while installing WinForms Edition.

To use a ComponentOne control, add it to the form or add a reference to the appropriate assembly to your project. In the following example, we will use C1BarCode.

If ComponentOne controls are not available in the Visual Studio Toolbox after installation, then users need to manually add these controls to the Toolbox.

Adding a Control to the Toolbox 

To manually add C1BarCode control to the Visual Studio Toolbox, follow these steps:

1. Open the Visual Studio IDE (Integrated Development Environment), and the desired Windows Forms project. Make sure the Toolbox is visible (select Toolbox in the View menu if necessary). Right-click within the Toolbox to open its context menu.
2. To make C1BarCode control appear on its own tab in the Toolbox, select Add Tab from the context menu and provide a tab name (For example, C1BarCode).
3. Right-click the tab where the component is to appear and select Choose Items from the context menu. Choose Toolbox Items dialog box opens.
4. In the dialog box, select the .NET Framework Components tab. Sort the list by Namespace (click the Namespace column header) and check the check boxes for all the components belonging to namespace C1.Win.BarCode. Note that there may be more than one components for each namespace.
