say suppose in my form there is a datagrid control and four buttons for first,last,next,previous. i want to populate datagrid with 10 records out of 100 and when some one will click on next button then datagrid will show next 10 records in this way user can navigate in records but will see at a time 10 records if there is 10 or more than 10 records in table. how could i do it in windows application using vb.net.please help me.

On the Datagrid you must set the paging property to true and you set the page size to 10. You do at least these two things without writing any code.

Follow this link to a good article of paging in ASP.NET

NB// its done in c#
