Rows no 5 to 8 has 'High','Low'. I want make them white bgcolor for those rows
Rows no 9 to 12 has 'High','Medium'. I want make them again gray bg color for

OK — just modify Leniel Macaferi’s answer: (I’m mixing a little w/ vb because I’m not a c# guy — sorry — the point should still be clear though I hope)

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
       // Display the company name in italics.
       Session("New_Pair_1") = e.Row.Cells[1].Text
       Session("New_Pair_2") = e.Row.Cells[2].Text

       If Session("New_Pair_1") <> Session("OLD_Pair_1") OR _
          Session("New_Pair_2") <> Session("OLD_Pair_2") Then
             //no pair match with last record's pair
             //step 1, change the backcolor
               If e.Row.BackColor = Color.FromName("Gray") Then
                  e.Row.BackColor = Color.FromName("White")
               Else
                  e.RowlBackColor = Color.FromName("Gray")
               End If
             //Step 2, reset the "OLD" session vars
               Session("OLD_Pair_1") = Session("New_Pair_1")
               Session("OLD_Pair_2") = Session("New_Pair_2")
       End If
    }
}
