Dear ALL,
i have one douts about my application.
this application i was developed by asp.net with vb.net.
my problem is,

i am trying to show my sql table data(ex: table name=test) into my web page.
and moreover in my table i have 2000 rows.
meanwhile i want to show all the rows where in that table on my web page.

But the problem is,
i displayed 2000 rows on my web page but its displaying too late which means after one minute only i got the result.
this is my problem.
Note : but if i have show just 20 rows then it will come very fast but 2000 rows will not.

please find my below source code and let me know where i made the mistake.
