Why do you want the pagination on the scrollview? If you want to scroll to the specified page. you can call 'gotoPage' method with the page number.
var page = 100;
$('#dg').datagrid('gotoPage', page);
If you want to scroll to the specified row, you can call 'scrollTo' method with the row index.
$('#dg').datagrid('scrollTo', 200); // scroll to the row 200
