Its a major problem faced while processing DB request else functions etc . The problem is when we perform command on database it takes time of few seconds, at that time my applications main window becomes halted. when i performs command on database execution returns on main application when whole command is executed on database. Just Like "NonQuery()" Lets assume we are working on asp.net 4.0 and sending request to view.  i am showing a form before it and closing that form after the command, but problem is i am putting a GIF image on the form, because exection is halted on main application, the gif don't shows animation until the command is executed. so that i putted it on a BackGroundWorker, but main thread is halted so its child tread also become halt. we can not put database transaction in background worker, becuase sometime working is depended on result retrieved from database, and we want to halt application untill data is not fetched, but in this case ...

Paging is one the functionality which we can achieved in many ways. So many plugins,technologies used for development. My sir already used in 2008, I think over to tried it in by different way. It found that Microsoft provides pagination feature with SQL Server 2012. We can acheived it by row_number() and minimum ids etc But from SQL Server 2012 we can do pagination by using FETCH and OFFSET. From above records, I need to split next 6 records after 32 Address ID. So doing pagination is a two-step process: - First mark the start of the row by using “OFFSET” command. Second specify how many rows you want to fetch by using “FETCH” command. Query :  1. Fetching records from 0 to above SELECT * FROM [Address]  order by AddressID offset 0 rows – start from zero Fetch Next 6 Rows only 2. Fetching records from 32 to next 6 records paging. SELECT * FROM [Address]  order by AddressID offset 6 rows  Fetch Next 6 Rows only [...
