Remarks

Use the ButtonCount property to specify the number of buttons to display in a NumericPagerField object. Each button corresponds to a page number. If the NumericPagerField object has more pages than the number specified for ButtonCount, the control displays a next-page button that lets users access the next set of pages.

The NumericPagerField object displays buttons only for existing page numbers. If the NumericPagerField object has fewer pages to show than the number specified for ButtonCount, the control shows fewer buttons than the number specified by this property.
