プロパティを使用して、 DataGridコントロールのページャー要素に同時に表示する数値ボタンの数を指定します。 PageButtonCountUse the PageButtonCount property to specify the number of numeric buttons to display concurrently in the pager element of the DataGrid control. このModeプロパティを有効にするPagerMode.NumericPagesには、プロパティをに設定する必要があります。The Mode property must be set to PagerMode.NumericPages for this property to have any effect.

このプロパティで指定されてDataGridいるよりも多くのページがコントロールに存在する場合、省略記号ボタン (...) がページャー要素に表示されます。If there are more pages in the DataGrid control than specified in this property, ellipsis buttons (...) are displayed in the pager element. このボタンをクリックすると、次または前の数値ボタンのセットが表示されます。When clicked, these buttons display the next or previous set of numeric buttons.
