difference between serverside paging and clientside paging in radgrid ?

[حمید]

Hi

I saw in your sample online (ASP.NET AJAX) , for select data use this blow command in sqldatasource :

select  *   from  xxx

 

so , if my table has  a lot of  record , all of them  transfer to client , all right?

 

how can i paging radgrid  that  only  contains  pagesize ( 10 or 20 ) rows ( fetch from server ) ?

 

what difference between  serverside and clientside paging ?

 

thanks
