PlacementMode Enumeration

July 28, 2014

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Specifies the preferred location for positioning a ToolTip relative to a visual element.

Namespace:  System.Windows.Controls.Primitives
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public enum PlacementMode
<objectproperty = "enumMemberName"/>

Member nameDescription
BottomIndicates that the preferred location of the tooltip is at the bottom of the target element.
RightIndicates that the preferred location of the tooltip is at the right of the target element.
MouseIndicates that the preferred location of the tooltip is at the pointer location.
LeftIndicates that the preferred location of the tooltip is at the left of the target element.
TopIndicates that the preferred location of the tooltip is at the top of the target element.

Use members of PlacementMode to set the Placement property of ToolTip or ToolTipService. Setting the Placement property on ToolTipService takes precedence over the Placement value of ToolTip, when the tooltip is activated.

If the tooltip does not fit within the bounds of the page at the specified placement, it is automatically moved to a location where it fits. The tooltip is first moved to the opposite location of the specified placement, and then to the other locations in a top-to-bottom, left-to-right order. If the tooltip does not fit completely at the top, bottom, left, or right of the target element, the tooltip is positioned at the right and is clipped. For example, if you specify Top, and the tooltip does not fit within the bounds of the page at the top of the target element, the tooltip is moved to the bottom of the target. If it does not fit at the bottom, it is moved to the left, and if it does not fit at the left it is moved to the right of the target.

If the tooltip exceeds the width of the page, it is clipped.

If the tooltip is automatically moved, the Placement value for the ToolTip or ToolTipService is not changed.
