ComboBox.DropDownStyleプロパティをComboBoxComboBoxStyleに設定してコントロールを初期化する方法を次のコード例に示します。The following code example demonstrates how to initialize a ComboBox control by setting the ComboBox.DropDownStyle property to a ComboBoxStyle value.

   // 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;
      array<String^>^ employees = {"Hamilton, David","Hensien, Kari",
         "Hammond, Maria","Harris, Keith","Henshaw, Jeff D.",

         "Heidepriem, Brandon D."};
      ComboBox1->Items->AddRange( employees );
      this->ComboBox1->Location = System::Drawing::Point( 136, 32 );
      this->ComboBox1->IntegralHeight = false;
      this->ComboBox1->MaxDropDownItems = 5;
      this->ComboBox1->DropDownStyle = ComboBoxStyle::DropDownList;
      this->ComboBox1->Name = "ComboBox1";
      this->ComboBox1->Size = System::Drawing::Size( 136, 81 );
      this->ComboBox1->TabIndex = 0;

      // Associate the event-handling method with the 
      // SelectedIndexChanged event.
      this->ComboBox1->SelectedIndexChanged +=
         gcnew System::EventHandler( this, &Form1::ComboBox1_SelectedIndexChanged );
   }
