Telerik UI for ASP.NET are added automatically to the Visual Studio Toolbox during installation. However if you are using the ZIP distribution or EXE installation, you can do this manually as described below.
To add Telerik controls to the Toolbox manually and to be able to easily deploy the components in your WebForms in Design mode, follow the steps below:
Open your application in Visual Studio.
Expand the Toolbox.
Expand the General section. Alternatively, you can create a new section by selecting
the Add Tab option from the context menu (right click anywhere in the toolbox).
When the new tab is added you can choose its name (e.g. Telerik UI for ASP.NET AJAX QX YYYY .NET 4.0).
Right-click in the General section (or the new one you just created) and open Choose Items.
On the .NET Framework Components tab, click Browse.
Browse to the installation folder, open the bin40 folder and select the Telerik.Web.UI.dll.
If the Windows Installer MSI Package was used to install Telerik UI for ASP.NET AJAX, the bin40
folder is located inC:\Program Files\Telerik\RadControls for ASPNET AJAX Q[X] YYYY\Bin40
If the ZIP was used to install the Telerik controls, the bin40
folder is located in the folder where the installation files have been unzipped.
Please, note that if you want to add Telerik controls for .NET 3.5 or .NET 4.5 web project you should select the
Telerik.Web.UI.dll from the C:\Program Files\Telerik\RadControls for ASPNET AJAX Q[X] YYYY\Bin35
or ~\Bin45 folder.
Telerik controls are not automatically installed into any configuration of Visual Studio Express because the end-user
license agreement (EULA) of VS Express does not allow third-party extensions to be registered.
