次のコード例は CheckedListBoxSelectionMode リスト内の1つの項目を選択できるようにを設定して、コントロールを初期化する方法を示しています。The following code example demonstrates initializing a CheckedListBox control by setting the SelectionMode to allow one item in the list to be selected.

この例を実行するには、という名前のを含むフォームに次のコードを貼り付け、 CheckedListBox CheckedListBox1 InitializeCheckListBox フォームのコンストラクターまたは Load メソッドからメソッドを呼び出します。To run the example, paste the following code in a form containing a CheckedListBox named CheckedListBox1 and call the InitializeCheckListBox method from the form's constructor or Load method.

   // This method initializes CheckedListBox1 with a list of all 
   // the controls on the form. It sets the selection mode
   // to single selection and allows selection with a single click.
   // It adds itself to the list before adding itself to the form.

      this->CheckedListBox1 = gcnew CheckedListBox;
      this->CheckedListBox1->Location = System::Drawing::Point( 40, 90 );
      this->CheckedListBox1->CheckOnClick = true;
      this->CheckedListBox1->Name = "CheckedListBox1";
      this->CheckedListBox1->Size = System::Drawing::Size( 120, 94 );
