Control.FindForm, méthode
Mise à jour : novembre 2007
Récupère le formulaire sur le lequel se trouve le contrôle.
Assembly : System.Windows.Forms (dans System.Windows.Forms.dll)
La valeur de la propriété Parent du contrôle peut être différente de Form retourné par la méthode FindForm. Par exemple, si un contrôle RadioButton est contenu dans un contrôle GroupBox, et si GroupBox se trouve sur Form, le Parent du contrôle RadioButton est GroupBox et le Parent du contrôle GroupBox est Form.
L'exemple de code suivant recherche le formulaire qui contient le bouton spécifié.
// 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; }

control.set_BackColor(Color.get_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.set_Text("The Form of My Control");
myForm.set_BackColor(Color.get_Red());
