Bind GridView with many records

I have a GridView which shows only 50 records at a time through paging. If i bind that to a source say containing 150 records, it works like charm but when the record size increases drastically to 10,00000, it took ages to load data.. So, i want to know is there any way of just loading 50 records at a time which are visible??

What is the solution for “The Type or namespace ‘AjaxControlToolkit’ could not be found…”?
