Shuffling rows in Gridview

[Gowtham]

I have radgrid for which I have binded data from code behind, I have two buttons next to my grid control, one moveup button and movedown button. On selecting a particular row on the grid and on click of moveup button I have to move the row up. How do I exchange the rows?

bind the grid to a data source upon initial entry - and store that data source
sort and key the grid on a generated number
when the flip columns command is issued, swap the generated keys of the row - and rebind

does the grid also update?
