    I have several custom WPF controls whose visual representations are defined by a XAML template. My goal is to define a RadContextMenu in a ResourceDictionary and then, in code, assign it to be the context menu for my custom controls, similary to the following:

    ResourceDictionary resourceDictionary = new ResourceDictionary();
                resourceDictionary.Source = new Uri(
                    "MyLibrary;component/Resources/Resources.xaml", UriKind.Relative);
      
                Grid mainGrid = Template.FindName("mainGrid", this) as Grid;
                if(mainGrid != null)
                {
                    RadContextMenu.SetContextMenu(this, (RadContextMenu)resourceDictionary["DefaultControlContextMenu"]);
                }

    At runtime, the RadContextMenu gets assigned correctly, but whenever I right-click on my custom control the following exception is thrown:

    System.InvalidOperationException: Cannot perform action because the specified Storyboard was not applied to this object for interactive control.

    I've noticed that others have gotten a similar exception with the RadTreeView and RadTransitionControl, and I need to know what to do for a workaround on this. Is the problem related to the fact that I am using a control template?

    Thanks,

    Greg

    Hello Gregory,

    Attaching one instance of RadContextMenu to multiple controls is not supported scenario. 
    Could you send us example so that we can investigate it?
