Exemples

L’exemple de code suivant ajoute deux objets Control à la Control.ControlCollection de la classe dérivée Panel.The following code example adds two Control objects to the Control.ControlCollection of the derived class Panel. L’exemple requiert que vous ayez créé un contrôle Panel et un contrôle Button sur un Form.The example requires that you have created a Panel control and a Button control on a Form. Lorsque vous cliquez sur le bouton, deux contrôles RadioButton sont ajoutés au Control.ControlCollectiondu panneau.When the button is clicked, two RadioButton controls are added to the panel's Control.ControlCollection.

   // Create two RadioButtons to add to the Panel.
private:
   RadioButton^ radioAddButton;
   RadioButton^ radioRemoveButton;

   // Add controls to the Panel using the AddRange method.
   void addRangeButton_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      radioAddButton = gcnew RadioButton;
      radioRemoveButton = gcnew RadioButton;
      
      // Set the Text the RadioButtons will display.
      radioAddButton->Text = "radioAddButton";
      radioRemoveButton->Text = "radioRemoveButton";
      
      // Set the appropriate location of radioRemoveButton.
      radioRemoveButton->Location = System::Drawing::Point( radioAddButton->Location.X, radioAddButton->Location.Y + radioAddButton->Height );
      
      //Add the controls to the Panel.
      array<Control^>^controlArray = {radioAddButton,radioRemoveButton};
      panel1->Controls->AddRange( controlArray );
   }
// Create two RadioButtons to add to the Panel.
private RadioButton radioAddButton = new RadioButton();
private RadioButton radioRemoveButton = new RadioButton();

// Add controls to the Panel using the AddRange method.
private void addRangeButton_Click(object sender, System.EventArgs e)
{
   // Set the Text the RadioButtons will display.
   radioAddButton.Text = "radioAddButton";
   radioRemoveButton.Text = "radioRemoveButton";
            
   // Set the appropriate location of radioRemoveButton.
   radioRemoveButton.Location = new System.Drawing.Point(
     radioAddButton.Location.X, 
     radioAddButton.Location.Y + radioAddButton.Height);
            
   //Add the controls to the Panel.
   panel1.Controls.AddRange(new Control[]{radioAddButton, radioRemoveButton});
}
' Create two RadioButtons to add to the Panel.
Dim RadioAddButton As RadioButton = New RadioButton()
Dim RadioAddRangeButton As RadioButton = New RadioButton()

' Add controls to the Panel using the AddRange method.
Private Sub AddRangeButton_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles AddRangeButton.Click
    ' Set the Text the RadioButtons will display.
    RadioAddButton.Text = "RadioAddButton"
    RadioAddRangeButton.Text = "RadioAddRangeButton"

    ' Set the appropriate location of RadioAddRangeButton.
    RadioAddRangeButton.Location = New System.Drawing.Point( _
    RadioAddButton.Location.X, _
    RadioAddButton.Location.Y + RadioAddButton.Height)

    ' Add the controls to the Panel.
    Panel1.Controls.AddRange(New Control() {RadioAddButton, RadioAddRangeButton})
End Sub

Remarques

Les objets Control contenus dans le tableau controls sont ajoutés à la fin de la collection.The Control objects contained in the controls array are appended to the end of the collection.

Vous pouvez utiliser la méthode AddRange pour ajouter rapidement un groupe d’objets Control à la collection au lieu d’ajouter manuellement chaque Control à la collection à l’aide de la méthode Add.You can use the AddRange method to quickly add a group of Control objects to the collection instead of manually adding each Control to the collection using the Add method.

Pour supprimer un Control que vous avez ajouté précédemment, utilisez les méthodes Remove, RemoveAtou Clear.To remove a Control that you previously added, use the Remove, RemoveAt, or Clear methods.

Notes pour les héritiers

Lors de la substitution d' AddRange(Control[]) dans une classe dérivée, veillez à appeler la méthode AddRange(Control[]) de la classe de base pour vous assurer que les contrôles sont ajoutés à la collection.When overriding AddRange(Control[]) in a derived class, be sure to call the base class's AddRange(Control[]) method to ensure that the controls are added to the collection.
