# How to: Position a ToolTip
This example shows how to specify the position of a tooltip on the screen.  
  
## Example  
 You can position a tooltip by using a set of five properties that are defined in both the <xref:System.Windows.Controls.ToolTip> and <xref:System.Windows.Controls.ToolTipService> classes. The following table shows these two sets of five properties and provides links to their reference documentation according to class.  
  
### Corresponding tooltip properties according to class  
  
|<xref:System.Windows.Controls.ToolTip?displayProperty=nameWithType> class properties|<xref:System.Windows.Controls.ToolTipService?displayProperty=nameWithType> class properties|  
|--------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------|  
|<xref:System.Windows.Controls.ToolTip.Placement%2A?displayProperty=nameWithType>|<xref:System.Windows.Controls.ToolTipService.Placement%2A?displayProperty=nameWithType>|  
|<xref:System.Windows.Controls.ToolTip.PlacementTarget%2A?displayProperty=nameWithType>|<xref:System.Windows.Controls.ToolTipService.PlacementTarget%2A?displayProperty=nameWithType>|  
|<xref:System.Windows.Controls.ToolTip.PlacementRectangle%2A?displayProperty=nameWithType>|<xref:System.Windows.Controls.ToolTipService.PlacementRectangle%2A?displayProperty=nameWithType>|  
|<xref:System.Windows.Controls.ToolTip.HorizontalOffset%2A?displayProperty=nameWithType>|<xref:System.Windows.Controls.ToolTipService.HorizontalOffset%2A?displayProperty=nameWithType>|  
|<xref:System.Windows.Controls.ToolTip.VerticalOffset%2A?displayProperty=nameWithType>|<xref:System.Windows.Controls.ToolTipService.VerticalOffset%2A?displayProperty=nameWithType>|  
  
 If you define the contents of a tooltip by using a <xref:System.Windows.Controls.ToolTip> object, you can use the properties of either class; however, the <xref:System.Windows.Controls.ToolTipService> properties take precedence. Use the <xref:System.Windows.Controls.ToolTipService> properties for tooltips that are not defined as <xref:System.Windows.Controls.ToolTip> objects.  
  
 The following illustrations show how to position a tooltip by using these properties. Although, the [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] examples in these illustrations show how to set the properties that are defined by the <xref:System.Windows.Controls.ToolTip> class, the corresponding properties of the <xref:System.Windows.Controls.ToolTipService> class follow the same layout rules. For more information about the possible values for the Placement property, see [Popup Placement Behavior](popup-placement-behavior.md).  

 The following image shows tooltip placement by using the Placement property:

 The following image shows tooltip placement by using the Placement and PlacementRectangle properties:

 The following image shows tooltip placement by using the Placement, PlacementRectangle, and Offset properties:

 The following example shows how to use the <xref:System.Windows.Controls.ToolTip> properties to specify the position of a tooltip whose content is a <xref:System.Windows.Controls.ToolTip> object.
