[Solved] Assigning RadContextMenu to Custom Templated Control

[Gregory]

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?
