    Hi I'm trying to use the itemFormatter to highlight a cell,
    however it seems to be highlighting random cells when i scroll the grid left to right and vis-avis.
    I have attached an example where I wanted to highlight the first cell. If you try to scroll horizontally, you will see it randomly highlights other cells as well.

    Hi Alvin,
    The grid recycles cells, so you have to reset the background if you change it.
    Please use the following code snippet to avoid that problem

    if (isCell) {
    var backColor="",
    color="";
    if (r == 0 && c == 0) {
    backColor = '#ffecec';
    color = '#de0000';
    }
    cell.style.backgroundColor = backColor;
    cell.style.borderBottomColor = color;
    }


    Thanks,
    Manish Kumar Gupta
