Control.BackgroundImageLayoutChanged Control.BackgroundImageLayoutChanged Control.BackgroundImageLayoutChanged Control.BackgroundImageLayoutChanged Event


發生於 BackgroundImageLayout 屬性變更時。Occurs when the BackgroundImageLayout property changes.

 event EventHandler ^ BackgroundImageLayoutChanged;
public event EventHandler BackgroundImageLayoutChanged;
member this.BackgroundImageLayoutChanged : EventHandler 
Public Custom Event BackgroundImageLayoutChanged As EventHandler 


下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在範例中,事件處理常式會報告一次BackgroundImageLayoutChanged事件。In the example, an event handler reports on the occurrence of the BackgroundImageLayoutChanged event. 此報表可協助您了解事件發生的時機,並可協助您偵錯。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或事件經常發生,請考慮更換MessageBox.Show具有Console.WriteLine或將訊息附加到多行TextBoxTo report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要執行範例程式碼,將它貼至專案,其中包含繼承自類型的執行個體Control,這類ButtonComboBoxTo run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. 然後將其命名執行個體Control1,並確保與關聯的事件處理常式BackgroundImageLayoutChanged事件。Then name the instance Control1 and ensure that the event handler is associated with the BackgroundImageLayoutChanged event.

     Handles Control1.BackgroundImageLayoutChanged
