Beispiele

Im folgenden Codebeispiel wird zunächst ein TabControl mit drei TabPageerstellt. In diesem Beispiel wird die Remove -Methode verwendet, um eine einzelne Registerkartenseite zu entfernen, insbesondere tabPage2 aus der tabControl1 Steuerelementauflistung. Beachten Sie, dass die TabPages -Eigenschaft die tabControl1 Steuerelementauflistung abruft, um Dieser Auflistung Registerkartenseiten hinzuzufügen und daraus zu entfernen.

Verwenden Sie in diesem Beispiel die System.Drawing Namespaces und System.Windows.Forms .

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;
      array<System::String^>^tabText = {"tabPage1","tabPage2","tabPage3"};
      this->tabPage1 = gcnew TabPage( tabText[ 0 ]->ToString() );
      this->tabPage2 = gcnew TabPage( tabText[ 1 ]->ToString() );
      this->tabPage3 = gcnew TabPage( tabText[ 2 ]->ToString() );
      
      // Populates the tabControl1 with three tab pages.
      array<TabPage^>^tabPages = {tabPage1,tabPage2,tabPage3};
      this->tabControl1->TabPages->AddRange( tabPages );
      
      // Gets the tabControl1 controls collection.
      // Removes the tabPage2 from the collection.
      this->tabControl1->TabPages->Remove( tabPage2 );
      this->tabControl1->Location = Point(25,25);
      this->tabControl1->Size = System::Drawing::Size( 250, 250 );
      this->ClientSize = System::Drawing::Size( 300, 300 );
      this->Controls->Add( tabControl1 );
   }
