            {

                var row= e.Item.FindControl("row");
                //how do I use it? How do I add "class" (if not exists) to "row"?

That object is an HtmlDataRow:

HtmlTableRow row = e.Item.FindControl("row") as HtmlTableRow;
if (row != null )
{
    if (string.isNullOrEmpty(row.Attributes["class"])) 
    {
         row.Attributes["class"] = "myClass"; 
    }
    else
    {
         row.Attributes["class"] = string.Format( "{0} {1}", row.Attributes["class"], "myClass");
    }
 }
