Hello,

when I start a brand new Telerik WPF project, and want to add a RadGridView component to the main window, the following error message shows:

Method not found: 'Telerik.Windows.Controls.SortingState Telerik.Windows.Controls.GridViewColumn.get_SortingState()'.

I just upgraded to the latest Telerik WPF version.

Please advise.

Thx

Hello Patrick,

Exceptions like the one that you have observed, might happen if there are conflicting versions of the Telerik UI for WPF dlls. May I ask you to check whether all of the referenced dlls are the same version (for example 2018.3.911) and also check out whether all of the referenced binaries are either Xaml or NoXaml?

What I can suggest in order to make sure that Visual Studio has not cached any old references, is to delete all of the referenced dlls, add them again, delete the bin and obj folders and perform a clean and rebuild on the project. Can you give this suggestion a try and let me know how it goes?

If the above suggestion does not help, may I ask you to open a new support ticket and send over a sample project which reproduces the issue, so that I can check it out on my end?

I hope you find this helpful.

Regards,
