    ContextMenu is not part of VisualTree and hence you cannot do any DataBinding Directly to ContextMenu. Refer my answer here stackoverflow.com/questions/30104193/… Commented May 13, 2015 at 14:41
  • Thanks I saw the link. Can you give example of how to use Tag property to overcome this ? Commented May 13, 2015 at 14:50
  • Can you post the XAML and for which control you want to add contextmenu Commented May 13, 2015 at 15:52
  • I have reedited to include the XAML code. Basically the contextmenu is shown when right click on the datarow of a datagrid. the name of the contextmenu is StatisticsFunctionsShowMenu in the xaml. Thank you very much. Commented May 13, 2015 at 22:03
