GridView.BottomPagerRow Property

Gets a GridViewRow object that represents the bottom pager row in a GridView control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

'Declaration
<BrowsableAttribute(False)> _
Public Overridable ReadOnly Property BottomPagerRow As GridViewRow

Property Value

Type: System.Web.UI.WebControls.GridViewRow
A GridViewRow that represents the bottom pager row in the control.

When paging is enabled (by setting the AllowPaging property to true), an additional row called the pager row is automatically displayed in the GridView control. The pager row contains controls that allow the user to navigate to the other pages, and can be displayed at the top, the bottom, or both the top and bottom of the control. Use the BottomPagerRow property to programmatically access the GridViewRow object that represents the bottom pager row in the GridView control.

NoteNote

The BottomPagerRow property is available only after the GridView control creates the bottom pager row in the RowCreated event.

This property is commonly used when you need to programmatically manipulate the bottom pager row, for example when adding custom content. Any modification to the BottomPagerRow property must be performed after the GridView control has been rendered; otherwise, the GridView control will overwrite any changes.

The following example demonstrates how to use the BottomPagerRow property to access the bottom pager row in a GridView control. The BottomPagerRow property is used to retrieve a DropDownList control from the pager row.
