ToolTipService.ToolTipClosingEvent ToolTipService.ToolTipClosingEvent ToolTipService.ToolTipClosingEvent ToolTipService.ToolTipClosingEvent Field

Definition

Identifies the ToolTipClosing event that is exposed by objects that use the ToolTipService service to display tooltips.

public: static initonly System::Windows::RoutedEvent ^ ToolTipClosingEvent;
public static readonly System.Windows.RoutedEvent ToolTipClosingEvent;
 staticval mutable ToolTipClosingEvent : System.Windows.RoutedEvent
Public Shared ReadOnly ToolTipClosingEvent As RoutedEvent 

Field Value

Examples

The following example shows how to set an event handler for the ToolTipClosing event. In this case, the event handler is actually for FrameworkElement.ToolTipClosing, because the Ellipse where the handler is attached is a derived class of FrameworkElement.

ellipse2.AddHandler(ToolTipService.ToolTipOpeningEvent,
    new RoutedEventHandler(whenToolTipOpens));
ellipse2.AddHandler(ToolTipService.ToolTipClosingEvent,
    new RoutedEventHandler(whenToolTipCloses));
ellipse2.AddHandler(ToolTipService.ToolTipOpeningEvent, New RoutedEventHandler(AddressOf whenToolTipOpens))
ellipse2.AddHandler(ToolTipService.ToolTipClosingEvent, New RoutedEventHandler(AddressOf whenToolTipCloses))

void whenToolTipOpens(object sender, RoutedEventArgs e)
{
    Ellipse ell = new Ellipse();
    if (sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse"))
    {
        ell = (Ellipse)sender;
        ell.Fill = Brushes.Blue;
    }
    else if (sender.GetType().FullName.Equals(
                             "System.Windows.Controls.ToolTip"))
    {
        ToolTip t = (ToolTip)sender;
        Popup p = (Popup)t.Parent;
        ell = (Ellipse)p.PlacementTarget;
        ell.Fill = Brushes.Blue;
    }
}

void whenToolTipCloses(object sender, RoutedEventArgs e)
{
    Ellipse ell = new Ellipse();
    if (sender.GetType().FullName.Equals(
                      "System.Windows.Shapes.Ellipse"))
    {
        ell = (Ellipse)sender;
        ell.Fill = Brushes.Gray;
    }
    else if (sender.GetType().FullName.Equals(
                           "System.Windows.Controls.ToolTip"))
    {
        ToolTip t = (ToolTip)sender;
        Popup p = (Popup)t.Parent;
        ell = (Ellipse)p.PlacementTarget;
        ell.Fill = Brushes.Gray;
    }
}


Private Sub whenToolTipOpens(ByVal sender As Object, ByVal e As RoutedEventArgs)
	Dim ell As New Ellipse()
	If sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse") Then
		ell = CType(sender, Ellipse)
		ell.Fill = Brushes.Blue
	ElseIf sender.GetType().FullName.Equals("System.Windows.Controls.ToolTip") Then
		Dim t As ToolTip = CType(sender, ToolTip)
		Dim p As Popup = CType(t.Parent, Popup)
		ell = CType(p.PlacementTarget, Ellipse)
		ell.Fill = Brushes.Blue
	End If
End Sub

Private Sub whenToolTipCloses(ByVal sender As Object, ByVal e As RoutedEventArgs)
	Dim ell As New Ellipse()
	If sender.GetType().FullName.Equals("System.Windows.Shapes.Ellipse") Then
		ell = CType(sender, Ellipse)
		ell.Fill = Brushes.Gray
	ElseIf sender.GetType().FullName.Equals("System.Windows.Controls.ToolTip") Then
		Dim t As ToolTip = CType(sender, ToolTip)
		Dim p As Popup = CType(t.Parent, Popup)
		ell = CType(p.PlacementTarget, Ellipse)
		ell.Fill = Brushes.Gray
	End If
End Sub

Remarks

The ToolTipClosing event occurs immediately before a tooltip closes.

This field registers the behavior of the ToolTipClosingEvent event for classes that use this service. The FrameworkElement and FrameworkContentElement classes both implement the ToolTipService and expose this event through the common language runtime (CLR) accessors FrameworkElement.ToolTipClosing and FrameworkContentElement.ToolTipClosing.

If you specify the tooltip as a ToolTip object, the Closed event is also raised when the tooltip closes.
