Highlighted Row, Increment Variable

I have an asp.net with C# code behind page that displays the following. The information
is being pulled from an SQL database. Each row that is above 7:10am is highlighted.:

EntryDate    EntryTime     Employee
4/25/08      7:05:56 AM   
Scot                  
4/25/08      7:11:02 AM    Rick       
4/26/08     
9:05:00 AM    Jen                       
4/27/08      8:05:16 AM   
Mel                       
4/27/08      7:15:06 AM   
Bill                       
4/28/08      5:00:55 AM    Scot
I want to have a static variable for each employee called lateScot, lateJen, lateMel, lateRick, lateBill. For each row that is highlighted, I want to increment the counter of the employee by one. I am using the RowDataBound event to highlight as needed. But how can I use the SqlDataSource1_Selecting event to go through the and increment as needed based on highlighted rows?
 
protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
    {
       
    }
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string grr = e.Row.Cells[2].Text;

            DateTime ontime = Convert.ToDateTime(e.Row.Cells[1].Text);
            DateTime late = Convert.ToDateTime("12/30/1899 7:10:00 AM");
            
            if (ontime.TimeOfDay >= late.TimeOfDay && grr != "Mailman,Mailman" && grr != "Moses,Bill" && grr != "Bathroom,Women's" && grr != "Bathroom,Men's" && grr != "Sharm,Tonmoy")
            {
                e.Row.BackColor = System.Drawing.Color.Firebrick;
                e.Row.ForeColor = System.Drawing.Color.White;
            }                       
        }
    }
 
Thanks in advance,
Scot
