I never considered the context menu.  I will get this implemented.  By the way, you should really learn about attached events.  Instead of creating an event handler for every single menu item simply define it once on the context menu.

<ContextMenu MenuItem.Click="ContextMenu_Click">

Okay, done.  Simply download the latest source code and compile the solution in the Main folder.  Your context menus will work.

Thanks for the fix for the ContextMenu.  That seems to now work.

About your tip, I'm always willing to learn but when I did this, my event "sender" isn't a MenuItem (i.e. "menuitem" is null in the code below) and fails...

        private void Time_Click(object sender, RoutedEventArgs e)
            MenuItem menuitem = (sender as MenuItem);
            int time = int.Parse(menuitem.Tag.ToString());
            int hours = time/100;
            int minutes = time % 100;
            StartTimePicker.Value = new DateTime(1899, 12, 30, hours, minutes, 0);

Seems the calling control is the entire ContextMenu. What am I doing wrong?
