Control.SendToBack Control.SendToBack Control.SendToBack Control.SendToBack Method

定義

將控制項傳送到疊置順序的後面。Sends the control to the back of the z-order.

public:
 void SendToBack();
public void SendToBack ();
member this.SendToBack : unit -> unit
Public Sub SendToBack ()

備註

將控制項移到疊置順序最下層。The control is moved to the back of the z-order. 如果控制項是另一個控制項的子系,移動子控制項的疊置順序最下層。If the control is a child of another control, the child control is moved to the back of the z-order. 如果控制項是最上層控制項,這個方法將無法正常運作除非控制項處於現用狀態。If the control is a top-level control, this method will not work correctly unless the control is active. 最上層的控制項是控制項,例如Form,也就是沒有子系的另一個控制項。A top-level control is a control, such as a Form, that is not a child of another control. 現用控制項是隱藏的控制項,它具有輸入焦點。An active control is a visible control that has input focus. 若要使用SendToBack方法為非作用中的最上層的控制項,第一次呼叫BringToFront控制項上的方法。To use the SendToBack method with an inactive, top-level control, first call the BringToFront method on the control.
