Using this example as a base, I created a custom class to add a special right click menu onto any RadGridView item:
If I modify any single item to add "Icon = iconCopy, " into the properties, I get the following runtime error:
Message: Failed to assign to property 'System.Windows.Controls.ContentPresenter.Content'.
I've tried using "/Images/copyIcon.png" and "MyProject;component/Images/copyIcon.png"; the end result is the same. If I put the source with the either format in xaml on a RadContextMenu, I can see the actual intended image during design time, but I get the same runtime error during runtime.
What can I do to fix this so my icon will show? I am using Silverlight 5, on Runtime Version v4.0.30319, with Telerik Version 2014.1.224.1050.
