Hi,

Try the following code to achieve your scenario.
C#:

protected void RadGrid2_ExportCellFormatting(object sender, ExportCellFormattingEventArgs e)
{
        GridDataItem item = e.Cell.Parent as GridDataItem;
        if (item.ItemType == GridItemType.AlternatingItem)
            item.Style["background-color"] = "Red";
        else
            item.Style["background-color"] = "Blue";
 }

Thanks,
Shinu.
