i need to enhance the application which developed by other colleagues, the source code located at share folder such as \\10.1.1.1\App1
and i had map the share folder as network drive such as T: drive

my colleagues can open the apps by VS and work properly, but when i open it by VS2010, it cannot display the RadControl in Toolbox, display unrecognized tag prefix error message and cannot reference telerik function in code behind.

i had tried many methods that found on forum and website but doesn't work. e.g.

  • Using Caspol.exe to grant .NET applications rights to a remote ...
    Caspol.exe –m –ag 1.2 –url file://\\10.1.1.13/App1/* FullTrust
    Caspol.exe –m –ag 1.2 –url file://\\T:/* FullTrust
  • Add reference to web.config
    <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>
  • Remove dll from bin folder

Hi Joe,

Try adding the assembly to the GAC of your local machine. Please note that this issue is not specific to Telerik RadControls. You can find more useful information on the following articles to check how you can access .NET projects to be run from a shared location such as a Network drive.

If RadControls for ASP.NET AJAX does not appear in the Visual Studio Toolbox the main reason behind this is the Visual Studio Extensions feature of the RadControls for ASP.NET AJAX installer was not installed. The recommended solution is to uninstall RadControls for ASP.NET AJAX (If installed) and run the installer again. Click the "Custom" button in the Setup Type screen and ensure the "Visual Studio Extensions for Visual Studio xxxx" feature is selected for install where xxxx can be the version such as Visual Studio 2010 etc. Another possible reason can be Custom/third-party/Telerik exe-installer were used to register RadControls to the toolbox, that prevent the ToolboxControlInstaller package of the IDE to run correctly.

Thanks,
Shinu.
