We are
using the grid which will have vertical scroll bar and we remove and add the
rows (Refresh the data in the grid) in a fixed interval. When the user is
scrolling down and views the data which is below at the time of refresh, the
scroll moves up automatically confusing the user. Is there any way to avoid
this behavior and update the grid seamlessly?


There is no direct way to refresh scrolling state of
grid. It has a method


           
grid.moveToVisible(this.getRowById(row_id).cells[0]);


which can scroll grid to necessary row, but it�s not
very useful in your case. You can use next code (it�s not public and can be
changed in next versions of grid):


           
var z=mygrid.objBox.scrollTop;


           
… refresh

           
mygrid.objBox.scrollTop=z;
