TextBoxBase.HideSelectionChanged 事件


發生於 HideSelection 屬性的值已變更時。Occurs when the value of the HideSelection property has changed.

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




下列程式碼範例將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事件的發生情況 HideSelectionChangedIn the example, an event handler reports on the occurrence of the HideSelectionChanged event. 這份報告可協助您瞭解發生事件的時間,並協助您進行調試。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,請考慮將取代為 MessageBox.Show Console.WriteLine 或將訊息附加至多行 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,其中包含繼承自之類型的實例 TextBoxBase ,例如 TextBoxTextBoxBaseTo run the example code, paste it into a project that contains an instance of a type that inherits from TextBoxBase, such as a TextBox or TextBoxBase. 然後命名實例 TextBoxBase1 ,並確定事件處理常式與事件相關聯 HideSelectionChangedThen name the instance TextBoxBase1 and ensure that the event handler is associated with the HideSelectionChanged event.

private void TextBoxBase1_HideSelectionChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the TextBoxBase.HideSelectionChanged event.");
Private Sub TextBoxBase1_HideSelectionChanged(sender as Object, e as EventArgs) _ 
     Handles TextBoxBase1.HideSelectionChanged

   MessageBox.Show("You are in the TextBoxBase.HideSelectionChanged event.")

End Sub
