Control.PaddingChanged 事件

定義

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

範例

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. 在此範例中,事件處理常式會報告 PaddingChanged 事件的發生次數。In the example, an event handler reports on the occurrence of the PaddingChanged event. 此報表可協助您瞭解事件發生的時間,並可協助您進行調試。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經常發生的事件,請考慮以 Console.WriteLine 取代 MessageBox.Show,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,請將它貼到專案中,其中包含繼承自 Control 的類型實例,例如 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. 然後將實例命名為 Control1,並確定事件處理常式與 PaddingChanged 事件相關聯。Then name the instance Control1 and ensure that the event handler is associated with the PaddingChanged event.

private void Control1_PaddingChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.PaddingChanged event.");

}
Private Sub Control1_PaddingChanged(sender as Object, e as EventArgs) _ 
     Handles Control1.PaddingChanged

   MessageBox.Show("You are in the Control.PaddingChanged event.")

End Sub
