If you are not able to see the ASP.NET controls in the toolbox after installing ASP.NET Web Forms Edition, you can add them manually. To manually add the C1GridView control to the Visual Studio Toolbox:

1. Open Visual Studio.
2. From the View menu, select Toolbox and right-click to open the context menu.
3. Right-click the tab where the controls are added and select Choose Items from the context menu. The 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 components belonging to the namespace  C1.Web.Wijmo.Controls.C1GridView.
5. From the Visual Studio Toolbox, double-click the control or drag it onto your form. This adds the C1GridView control to your web form.
