示例

以下示例演示如何使用 SelectionChanged 事件。

// Add SelectionChanged event handler to event
m_selectionService->SelectionChanged += gcnew EventHandler( this, &ComponentClass::OnSelectionChanged );

// Add SelectionChanged event handler to event
m_selectionService.SelectionChanged += new EventHandler(OnSelectionChanged);

' Add SelectionChanged event handler to event
AddHandler m_selectionService.SelectionChanged, AddressOf OnSelectionChanged

/* This is the OnSelectionChanged handler method.  This method calls
    OnUserChange to display a message that indicates the name of the
    handler that made the call and the type of the event argument. */
void OnSelectionChanged( Object^ /*sender*/, EventArgs^ args )
{
   OnUserChange( "OnSelectionChanged", args->ToString() );
}

/* This is the OnSelectionChanged handler method.  This method calls
    OnUserChange to display a message that indicates the name of the
    handler that made the call and the type of the event argument. */
private void OnSelectionChanged(object sender, EventArgs args) 
{
    OnUserChange("OnSelectionChanged", args.ToString());
}

' This is the OnSelectionChanged handler method.  This method calls
'  OnUserChange to display a message that indicates the name of the
'  handler that made the call and the type of the event argument. 
Private Sub OnSelectionChanged(ByVal sender As Object, ByVal args As EventArgs)
   OnUserChange("OnSelectionChanged", args.ToString())
End Sub

注解

在处理此事件时尽量减少处理，因为在此事件处理程序中发生的处理可能会显著影响表单设计器的整体性能。
