Exemples

L’exemple de code suivant crée initialement un TabControl avec trois TabPage. Cet exemple utilise la Clear méthode pour effacer tous les contrôles de la tabControl1 collection de contrôles à une seule instance. Ensuite, l’exemple revient tabPage2 à la collection. Notez que la TabPages propriété est utilisée pour obtenir la tabControl1 collection de contrôles pour supprimer (et ajouter) des pages d’onglet de cette collection.

using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   TabPage^ tabPage3;

public:
   Form1()
   {
      this->tabControl1 = gcnew TabControl;
      this->tabPage1 = gcnew TabPage( "tabPage1" );
      this->tabPage2 = gcnew TabPage( "tabPage2" );
      this->tabPage3 = gcnew TabPage( "tabPage3" );
      
      // Populates the tabControl1 with three tab pages.
      array<TabPage^>^tabPages = {tabPage1,tabPage2,tabPage3};
      this->tabControl1->TabPages->AddRange( tabPages );
      
      // Removes all the tab pages from tabControl1.
      this->tabControl1->TabPages->Clear();
      
      // Adds the tabPage1 back to tabControl1.
      this->tabControl1->TabPages->Add( tabPage2 );
