25                     rows: data
26                 }
27             }
28             var dg = $(this);
29             var opts = dg.datagrid('options');
30             var pager = dg.datagrid('getPager');
31             pager.pagination({
32                 onSelectPage: function (pageNum, pageSize) {
33                     opts.pageNumber = pageNum;
34                     opts.pageSize = pageSize;
35                     pager.pagination('refresh', {
36                         pageNumber: pageNum,
37                         pageSize: pageSize

45             var start = (opts.pageNumber - 1) * parseInt(opts.pageSize);
46             var end = start + parseInt(opts.pageSize);
47             data.rows = (data.originalRows.slice(start, end));
