    Hello Blake,

     

    May you verify that you have added the full list of references related to RadGridView in your project?
    Since you have added references to the assembliesTelerik.Windows.Controls, Telerik.Windows.Data, Telerik.Windows.Controls.Input and Telerik.Windows.Controls.GridView  you should not get such error.


    Plese check this and let me know whether the issue still persists.

    I just recently updated my Telerik controls and again.

    The tag 'RadGridView' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation;clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView'. Line 20 Position 10.

    Hello Blake,

     
    You are getting this error, because you have mixed the namespaces you should use.

    Please use either this one:

    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

    or the recommended URI namespace:

    All the best,

    i have updated latest dll references in my silverlight 4 application.
    after updating latest dlls my application gives same error
    "Error 33 The tag 'RadGridView' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'. TestApp_1\MainPage.xaml 11 10 TestApp_1
    "

    i have used

     

    xmlns

     

     

    :telerik="http://schemas.telerik.com/2008/xaml/presentation"
    to add reference of telerik on xaml page.

    Is it required to have silverlight 5 version with latest telerik controls ?

    Can you confirm version of the Telerik binaries you are referring?

    Hello,

    What I could suggest you is to check if all the referenced assemblies are with the same version. If you still get this error then delete all project references to Telerik controls and remove all Telerik assemblies that are located in your project's folder. After that add the assemblies to the project again, Clean and Rebuild.

    I hope this solves the problem.
