If a table contains 20000 records . In a page at each time 100 records to be displayed.
What are the steps u will take to improve performance? will you use dataset or datareader?
Answer:
we have to use a dataset because on using datareader forward only paging can be achieved.
Suppose if you are at 1000 page and you want to go back to 999th page, if you use datareader it cannot be achieved, since it does not support backward navigation.
Dataset supports forward and backward navigation
