@oviya : The updating of the dataprovider will intern call the datagrid redraw
@ravi : this will sound like a hack but, you can have a ItemRenderer for you column and in it have a timer being placed calling any of your method within each interval of your choice. In that method you can call your ItemRenderer's refreshing logic, even if it is like calling some server to fetch you something. Now again, for each cell of that column you will be having Timer functions calling the refresh for you. This might be a trade off to choose, but certainly all other options to stop datagrid redraw will land you into more lines of code and that will be difficult to manage and work with all user actions which can be performed on a datagrid. Still you will had one UI issue for having those ItemRenderers display inapropriately when you take your mouse over any selected row, because your ItemRenderer will be redrawing each time your timer calls it.
