The following example assigns the same ContextMenu to two buttons and sets the HasDropShadow, Placement, PlacementRectangle, HorizontalOffset, and VerticalOffset properties to set the ContextMenu to different positions for each button.

<StackPanel>
  <StackPanel.Resources>
    <ContextMenu x:Key="myContextMenu">
      <MenuItem Header="Item"/>
    </ContextMenu>
  </StackPanel.Resources>

  <!--Both buttons use the same ContextMenu but use the
    properties on ContextMenuService to position them
    differently.-->
  <Button ContextMenu="{StaticResource myContextMenu}" 
          ContextMenuService.HasDropShadow="False" 
          ContextMenuService.Placement="Relative"
          ContextMenuService.HorizontalOffset="50"
          ContextMenuService.VerticalOffset="-10">
    button 1
  </Button>

  <Button ContextMenu="{StaticResource myContextMenu}" 
          ContextMenuService.HasDropShadow="True"
          ContextMenuService.Placement="Right"
          ContextMenuService.PlacementRectangle="0,0,30,30">
