Telerik Rad Menu type is not registered as safe

To leverage RadControls for ASP.NET Ajax, some required files must be deployed to each SharePoint Web Front End (WFE) server.

Once the required files are deployed, our ASP.NET AJAX can be added to the site by editing the site’s master page(s).

This section outlines the required steps that need to be taken to deploy RadControls for ASP.NET AJAX prior to implementing it within an existing SharePoint web site.

1. First you need to install Telerik.Web.UI.dll and Telerik.Web.Design.dll in the GAC (Global Assembly Cache) of your SharePoint server. There are two ways to do this:

a. Drag and drop Telerik.Web.UI.dll and Telerik.Web.Design.dll into C:\Windows\Assembly (in Windows Explorer)

b. Open Visual Studio 2005/2008/2010 Command Prompt and run the following commands (assuming Telerik.Web.UI.dll and Telerik.Web.Design.dll are in c:\Telerik)gacutil -i c:\Telerik\Telerik.Web.UI.dll

                  gacutil -i c:\Telerik\Telerik.Web.Design.dll

By adding the Telerik controls to sharepoint site, you hould tell SharePoint that the controls from the Telerik.Web.UI.dll (and Telerik.Web.Design.dll) are safe to use.

If not we will get this below error

To do so you should add a few <SafeControl> entries within the <SafeControls> section in your IS --> SharePoint Site's web.config:

<SafeControl Assembly="Telerik.Web.UI, Version=x.x.x.x, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TypeName="*" Safe="True" />

<SafeControl Assembly="Telerik.Web.UI, Version=x.x.x.x, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.Design" TypeName="*" Safe="True" />


Note that the version of the assembly is specified in each <SafeControl> tag. If deploying a different version of RadControls for ASP.NET Ajax, ensure that the version number is correct here.
