Contoh

Contoh berikut menunjukkan cara membuat dan memposisikan 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;

'Create an ellipse that will have a 
'ToolTip control. 
Dim ellipse1 As New Ellipse()
ellipse1.Height = 25
ellipse1.Width = 50
ellipse1.Fill = Brushes.Gray

'Create a tooltip and set its position.
Dim tooltip As 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.
Dim bdec As New BulletDecorator()
Dim littleEllipse As New Ellipse()
littleEllipse.Height = 10
littleEllipse.Width = 20
littleEllipse.Fill = Brushes.Blue
bdec.Bullet = littleEllipse
Dim tipText As New TextBlock()
tipText.Text = "Uses the ToolTip class"
bdec.Child = tipText
tooltip.Content = bdec

'set tooltip on ellipse
ellipse1.ToolTip = tooltip
