Datatable Paging

Hi

   I want all records should not not be uploaded in one go. Suppose in dropdown 10 records are given then First time should be bpught 10 records only . 

If there are 35 records then first 10 records should be shown , and if user select on page 4 then 31-35 records should be shown & if page 2 is clicked then 11-20 records should be shown

Thanks
