The connection was reset

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

i try different technique -

1. httpruntime executiontimeout="1800" maxrequestlength="51200"
2. adapter.SelectCommand.CommandTimeout = 1800;
3. Connection Timeout=1800 in connection string.

but noting happen. it works perfect in localhost but failed in live server

Your page/server not able to respond because of what you're doing. And increasing timeouts are also dirty trick which is not recommendable one.

That's not a good way to show that much data at a time in grid, End user won't like that much delay or hangs.,

Use paging/filtering while displaying the data.

In database side
SQL Server 2005 Paging Results[^]

In frontend
GridView Multiple Filter AJAX Control[^]
