public function get Parent () : Control public function set Parent (value : Control)
Eigenschaftenwert
Ein Control, das das übergeordnete Element oder das Container-Steuerelement des Steuerelements darstellt.Wenn Sie die Parent-Eigenschaft auf NULL (Nothing in Visual Basic) festlegen, wird das Steuerelement aus der Control.ControlCollection des aktuellen übergeordneten Steuerelements entfernt.
Im folgenden Codebeispiel werden mithilfe der Parent-Eigenschaft und der FindForm-Methode Eigenschaften für das übergeordnete Steuerelement einer Schaltfläche und dessen Formular festgelegt.
// 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 void button1_Click(object sender, System.EventArgs e) { // Get the control the Button control is located in. In this case a GroupBox. Control 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. Form myForm = button1.FindForm(); // Set the text and color of the form containing the Button. myForm.Text = "The Form of My Control"; myForm.BackColor = Color.Red; }
