Definition

Namespace:
System.Windows.Controls
Assembly:

public:
 property System::Windows::Controls::Primitives::PlacementMode Placement { System::Windows::Controls::Primitives::PlacementMode get(); void set(System::Windows::Controls::Primitives::PlacementMode value); };
[System.ComponentModel.Bindable(true)]
public System.Windows.Controls.Primitives.PlacementMode Placement { get; set; }
[<System.ComponentModel.Bindable(true)>]
member this.Placement : System.Windows.Controls.Primitives.PlacementMode with get, set
Public Property Placement As PlacementMode

Property Value

PlacementMode

One of the PlacementMode enumeration. The default is MousePoint.

Attributes
BindableAttribute

Examples

The following example shows how to use the Placement property and a placement mode to specify where the ContextMenu is placed.

<ContextMenu Placement="Bottom" PlacementRectangle="30,50,0,0">

Remarks

When the ContextMenu is assigned to the FrameworkElement.ContextMenu or FrameworkContentElement.ContextMenu property, the ContextMenuService changes this value of this property when the ContextMenu opens. If the user opens the ContextMenu by using the mouse, Placement is set to MousePoint. If the user opens the ContextMenu by using the keyboard, Placement is set to Center. If you want to change the position of the ContextMenu, set the ContextMenuService.Placement property on the FrameworkElement or FrameworkContentElement.

You can position a ContextMenu by setting the PlacementTarget, PlacementRectangle, Placement, HorizontalOffset, and VerticalOffsetProperty properties. These properties behave the same as they do for a Popup. For more information, see Popup Placement Behavior.
