Load grid like SQL Server Management Studio

Question

Hi
we have a windows forms project with grid.
I would like to emulate the behaviour of SQL Server management studio where upon executing the query, the results start filling in instantaneously and the process continues until all results have been fetched. This way the user doesnt have to wait at all.
Kindly advise whats the best way to achieve above.
Many Thanks
Abhishek

In a virtual mode datagridview, you should only read data when necessary. The whole point of generating extra DataGridView.CellValueNeeded events is to give you the option of not pulling all rows, only for currently visible ones (maybe a little more
for caching). 
You should at least cache the data of a row when a cell is accessed (it is likely you will query every column of a row). It also a good idea to cache several pages near the requested row, since the user may be scrolling up and down a bit and you may not
want to hit the database for every single row or every even single page. The few pages near the top and the bottom are also hot areas that are good for caching.  BackgroundWorker is kinda clumsy for this task, probably better write this in TPL and queue
data populating tasks when the user scroll up or down.
The caching part is your business logic and is not provided by Windows Forms.
