Contoh kode berikut menunjukkan cara menginisialisasi ComboBox kontrol dengan mengatur ComboBox.DropDownStyle properti ke ComboBoxStyle nilai.

   // Declare comboBox1 as a ComboBox.
internal:
   System::Windows::Forms::ComboBox^ ComboBox1;

private:
   // This method initializes the combo box, adding a large string array
   // but limiting the drop-down size to six rows so the combo box doesn't 
   // cover other controls when it expands.
   void InitializeComboBox()
   {
      this->ComboBox1 = gcnew System::Windows::Forms::ComboBox;
