Fetching 50 Records At A Time

Hi,
I get 5000 records on executing a query.
In the form, I would like to display 50 records at a time in the grid from this resulted query, so i create 100 link labels(dynamically created based on the no. of records resulted from the query) within a panel.

When clicked on link1, first 50 records should be displayed,on clicking link2 next 50 records(ie, 51 to 100) should be displayed and so on.
So , i wrote the query as---

select top(50)* from tblindividual where id not in (select top(intValue)id from tblindividual )

where intValue would be 50 for link2,100 for link3,150 for link4 and so on


If i want to fetch last 50 records of the query, intValue would be 4950.Here the "not in" list becomes very big(1,2,3,.......,4949,4950) and hence the query is becoming a bit slow...

Is there any other method(query) to get the same result??.. because i heard that using "not in" keyword would make query execution slow.
