protected void rpInCome_ItemDataBound(object sender, RepeaterItemEventArgs e)

{

  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)  
        {  
            Repeater rpInCome = (Repeater)sender;  
            try  
            {  
                PagedDataSource pds = (PagedDataSource)rpInCome.DataSource;  
                if (pds.Count == 0)  
                    return;  

                IEnumerator enumrator = pds.DataSource.GetEnumerator();  
                int ncount = 0;  
                while (enumrator.MoveNext() && ncount != e.Item.ItemIndex)  
                    ncount++;  

                DataRowView dr = (DataRowView)enumrator.Current;  

                double dValue = dr["CurrentEarn"] == DBNull.Value ? 0 : Convert.ToDouble(dr["CurrentEarn"].ToString());  
                HtmlControl c = (HtmlControl)e.Item.FindControl("row");  
                if (dValue < 0)  
                {  
                    c.Attributes["class"] = "green";  
                }  
                else if(dValue>0)  
                {  
                    c.Attributes["class"] = "red";  
                }  
            }  
            catch (Exception ex)  
            {  
                //  
            }  
    }  

}
