GroupBox.AutoSizeChanged 事件


發生於 AutoSize 屬性的值變更時。Occurs when the value of the AutoSize property changes.

 event EventHandler ^ AutoSizeChanged;
public event EventHandler AutoSizeChanged;
member this.AutoSizeChanged : EventHandler 
Public Custom Event AutoSizeChanged 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. 在此範例中,事件處理常式會報告 AutoSizeChanged 事件的發生次數。In the example, an event handler reports on the occurrence of the AutoSizeChanged 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,請將它貼入包含類型為 GroupBox 的實例的專案中(名為 GroupBox1)。To run the example code, paste it into a project that contains an instance of type GroupBox named GroupBox1. 然後確定事件處理常式與 AutoSizeChanged 事件相關聯。Then ensure that the event handler is associated with the AutoSizeChanged event.

private void GroupBox1_AutoSizeChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the GroupBox.AutoSizeChanged event.");

Private Sub GroupBox1_AutoSizeChanged(sender as Object, e as EventArgs) _ 
     Handles GroupBox1.AutoSizeChanged

   MessageBox.Show("You are in the GroupBox.AutoSizeChanged event.")

End Sub
