次のコード例では、派生NumericUpDownクラスを使用して、からUpDownBase派生したプロパティの一部を設定します。The following code example uses the derived class NumericUpDown and sets some of its properties derived from UpDownBase. このコードでは、 NumericUpDownコントロール、2つComboBoxのコントロール、および 3 CheckBoxつのコントロールがフォーム上に作成されている必要があります。This code requires that you have a NumericUpDown control, two ComboBox controls, and three CheckBox controls created on a form. コントロールTextAlign ComboBox にとBorderStyleというラベルを付けます。Label the ComboBox controls BorderStyle and TextAlign. CheckBox コントロールInterceptArrowKeysにラベルを付けます。UpDownAlign ReadOnlyLabel the CheckBox controls InterceptArrowKeys, ReadOnly, and UpDownAlign. このコードを使用すると、実行時にプロパティ値を変更し、それぞれがスピンボックスの外観と動作にどのように影響するかを確認できます。The code allows you to change the property values at run time and see how each affects the appearance and behavior of the spin box. BorderStyle: NoneFixed3D、およびとFixedSingleいうラベルが付いたコンボボックスに、次の項目を追加します。Add the following items to the combo box labeled BorderStyle: None, Fixed3D, and FixedSingle. LeftRight、およびとCenterいうラベルが付いたコンボボックスに、次の項目を追加します。Add the following items to the combo box labeled TextAlign: Left, Right, and Center.
