I have the follow behind code that I would like to place an additional condition into.   I need asssitence with the C# code behind.  I want to add additional highlight condition "Etops - Working" and highlight it "Yellow
when column 13 also meets this condition.

{

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
      if (e.Row.RowType==DataControlRowType.DataRow)
                if (e.Row.Cells[13].Text == "AOG" || e.Row.Cells[13].Equals(DBNull.Value))  
                {  
                    e.Row.BackColor = System.Drawing.Color.LightPink;  
                }
 }
