Based on your advise i went thru the GridPerf sample and accordingly did the following modification.. updation to grid is very fast and we are quite happy with the performance...
GridDataBoundGrid symbolGrid = new GridDataBoundGrid();
symbolGrid.VerticalThumbTrack = true;
Is there any other setting that would further boost up the performance ? the application we are working is a trading application and there is continous update happening on grid every second... even a millisecond performance jump is a bonus for us ...
Thx again for your help...
