Exemples

L’exemple de code suivant recherche le formulaire qui contient le bouton spécifié.The following code example finds the form that contains the specified button.

   // 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;
   }
// This example uses the Parent property and the Find method of Control to set

// that a Button control named button1 is located within a GroupBox control. The

// 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();

' This example uses the Parent property and the Find method of Control to set

' that a Button control named button1 is located within a GroupBox control. The

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

Remarques

La valeur de la propriété Parent du contrôle peut ne pas être la même que la Form retournée par la méthode FindForm.The control's Parent property value might not be the same as the Form returned by FindForm method. Par exemple, si un contrôle de RadioButton est contenu dans un contrôle GroupBox et que le GroupBox se trouve sur un Form, le RadioButton du contrôle Parent est le GroupBox et le GroupBox du contrôle Parent est le Form.For example, if a RadioButton control is contained within a GroupBox control, and the GroupBox is on a Form, the RadioButton control's Parent is the GroupBox and the GroupBox control's Parent is the Form.
