Use the FooterRow property to programmatically access the GridViewRow object that represents the footer row in a GridView control.
The FooterRow property is available only after the GridView control creates the footer row in the RowCreated event.
This property is commonly used when you need to programmatically manipulate the footer row, for example when adding custom content. Any modification to the FooterRow property must be performed after the GridView control has been rendered; otherwise, the GridView control will overwrite any changes.
