<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">
button 2
</Button>
</StackPanel>
Remarks
When the ContextMenu opens, the value is set to the value of SystemParameters.DropShadow. Setting this property to true
has no effect if the SystemParameters.DropShadow property is false
.
