XAML Values

placementModeValue

A named constant of the PlacementMode enumeration, such as Left.

Property Value

Type: System.Windows.Controls.Primitives.PlacementMode
The position of the tooltip in relation to its target visual element.

Setting the Placement property on ToolTipService takes precedence over the Placement value of ToolTip, when the tooltip is activated with the mouse.

If the tooltip does not fit within the bounds of the Silverlight plug-in 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 plug-in 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 browser, it is clipped.

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