Control.Parent プロパティ

コントロールの親コンテナを取得または設定します。

名前空間: System.Windows.Forms
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Visual Basic (宣言)
Public Property Parent As Control
Visual Basic (使用法)
Dim instance As Control
Dim value As Control

value = instance.Parent

instance.Parent = value
C#
public Control Parent { get; set; }
C++
public:
property Control^ Parent {
    Control^ get ();
    void set (Control^ value);
}
J#
/** @property */

プロパティ値

コントロールの親コントロールまたはコンテナ コントロールを表す Control

Parent プロパティ値を null 参照 (Visual Basic では Nothing) に設定すると、コントロールが現在の親コントロールの Control.ControlCollection から削除されます。

Parent プロパティと FindForm メソッドを使用して、ボタンおよびフォームの親コントロール上でプロパティを設定するコード例を次に示します。

Visual Basic
' This example uses the Parent property and the Find method of Control to set
' properties on the parent control of a Button and its Form. The example assumes
' that a Button control named button1 is located within a GroupBox control. The 
' example also assumes that the Click event of the Button control is connected to
' the event handler method defined in the example.
Private Sub button1_Click(sender As Object, e As System.EventArgs) Handles button1.Click
   ' Get the control the Button control is located in. In this case a GroupBox.
   Dim control As Control = button1.Parent
   ' Set the text and backcolor of the parent control.
   control.Text = "My Groupbox"
   control.BackColor = Color.Blue
   ' Get the form that the Button control is contained within.
   Dim myForm As Form = button1.FindForm()
   ' Set the text and color of the form containing the Button.
   myForm.Text = "The Form of My Control"
   myForm.BackColor = Color.Red
End Sub
