<object Placement="PlacementMode" .../>
Property Value
Type: System.Windows.Controls.Primitives.PlacementModeA PlacementMode enumeration value that determines the orientation of the ToolTip control when it opens, and that specifies how the control interacts with screen boundaries. The default is Mouse.
You can position a ToolTip 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.
The following example shows how to create and position a ToolTip.
<Ellipse Height="25" Width="50"
Fill="Gray"
HorizontalAlignment="Left"
ToolTipService.InitialShowDelay="1000"
ToolTipService.ShowDuration="7000"
ToolTipService.BetweenShowDelay="2000">
<Ellipse.ToolTip>
<ToolTip Placement="Right"
PlacementRectangle="50,0,0,0"
HorizontalOffset="10"
VerticalOffset="20"
HasDropShadow="false"
Opened="whenToolTipOpens"
Closed="whenToolTipCloses"
>
<BulletDecorator>
<BulletDecorator.Bullet>
<Ellipse Height="10" Width="20" Fill="Blue"/>
</BulletDecorator.Bullet>
<TextBlock>Uses the ToolTip Class</TextBlock>
</BulletDecorator>
</ToolTip>
</Ellipse.ToolTip>
</Ellipse>
//Create an ellipse that will have a //ToolTip control. Ellipse ellipse1 = new Ellipse(); ellipse1.Height = 25; ellipse1.Width = 50; ellipse1.Fill = Brushes.Gray; ellipse1.HorizontalAlignment = HorizontalAlignment.Left; //Create a tooltip and set its position. ToolTip tooltip = new ToolTip(); tooltip.Placement = PlacementMode.Right; tooltip.PlacementRectangle = new Rect(50, 0, 0, 0); tooltip.HorizontalOffset = 10; tooltip.VerticalOffset = 20; //Create BulletDecorator and set it //as the tooltip content. BulletDecorator bdec = new BulletDecorator(); Ellipse littleEllipse = new Ellipse(); littleEllipse.Height = 10; littleEllipse.Width = 20; littleEllipse.Fill = Brushes.Blue; bdec.Bullet = littleEllipse; TextBlock tipText = new TextBlock(); tipText.Text = "Uses the ToolTip class"; bdec.Child = tipText; tooltip.Content = bdec; //set tooltip on ellipse ellipse1.ToolTip = tooltip;
