Speed issues displaying data from large database

Load less data, or reduce the number of controls on the screen that are being updated. You can do this by using a tab control, or a wizard form.

I believe the term large database means a database with large no of records....so in this situation you need to concentrate on two layers of the application..

1. The database layer.
2. The application layer.

1. Tune your database for faster access of data. Tune your queries by examining the execution plan. implement proper indexing of the tables.

2. In the application layer, use paging for data access (say 100 data per page). Use Repeater control for displaying the data (it requires a bit effort, as there is no default layout, but reduces the amount of viewstate than DataGrid or any other rich data bound control). If possible load the page using Ajax, so that the user experience doesn't becomes tiring.
