Can you please post the Adapter's Select Command?
you can go for multiThreading so that the user simulteneously Browses as Records get filled???
Hi,
1 Way :
Optimize your Query to DB.
2 Way:
use SqlDataReader in place DataSet, SqlDataReader is a least 10 time faster than DataSet.
Create the Query only with the filters that each search need.
What DB are you using?

1. There is nothing can be changed in the "Select" statement. Just like that "Select * from table"
2. It should allow user to update, so cannot use datareader.
3. arif_eqbal, would you give me more details ?

Cant you filter the records a little, ie
Select * from table where something = 'something';
Surely the user has an idea of what they are after, and surely they arent going to look at all the records.

why dont u use a caching mechanism where u keep using the dataset in the cache unless a user updates the dataset then u reapply the query
