In this Example, we are using the pager template for paging.
DataKeyNames – Used for Getting Row in Row command.
Set the AllowPaging is to True and Set the PageSize is to your Page size count.
Eval – Used for Direct column Binding .
Within that script tag Container.DataItemIndex is used for Serial No.
