I was following the documentation for adding the RadControls to the Visual Studio 2008 Toolbox...
To add Telerik RadControls for Silverilght to the Toolbox manually and to be able to easily deploy the components in Design mode, follow the steps below:
- Open your application in Visual Studio 2008.
- Expand the Toolbox.
Expand the General Section.
Right-click in the General section and open Choose Items.
On the Silverlight Components tab, click Browse.
Browse to the Telerik RadControls for Silverlight installation folder, open the Binaries folder and select the Telerik.Windows.Controls.dll, Telerik.Windows.Controls.Input.dll, Telerik.Windows.Controls.MediaPlayer.dll, Telerik.Windows.Controls.Navigation.dll or Telerik.Windows.RadUploadHandler.dll. The Binaries folder is located in the folder where the installation files have been unzipped
Step 6 is where I have the problem. Is there something else I need to do?
