When paging is enabled (by setting the DetailsView.AllowPaging property to true), an additional row called the pager row is automatically displayed in the System.Web.UI.WebControls.DetailsView control. The pager row contains controls that allow the user to navigate to other records, and can be displayed at the top, the bottom, or both the top and bottom of the control. Use the DetailsView.TopPagerRow property to programmatically access the System.Web.UI.WebControls.DetailsViewRow object that represents the top pager row in the System.Web.UI.WebControls.DetailsView control.

This property is commonly used when you need to programmatically manipulate the top pager row, for example when adding custom content. Any modification to the DetailsView.TopPagerRow property must be performed after the System.Web.UI.WebControls.DetailsView control has been rendered; otherwise, the System.Web.UI.WebControls.DetailsView control will overwrite any changes.
