L’exemple de code suivant crée un TabControl avec deux TabPage objets. La SelectedIndex propriété définit tabPage2 comme page d’onglet actuellement sélectionnée à l’aide de sa valeur d’index.

using namespace System::Drawing;

      this->tabPage1 = gcnew TabPage;
      this->tabPage2 = gcnew TabPage;
      array<Control^>^tabControls = {this->tabPage1,this->tabPage2};
      this->tabControl1->Controls->AddRange( tabControls );
      this->tabControl1->Padding = Point(15,10);
      this->tabControl1->Location = Point(35,25);
      this->tabControl1->Size = System::Drawing::Size( 220, 220 );
      
      // Selects tabPage2 using SelectedIndex.
      this->tabControl1->SelectedIndex = 1;
