by looking at the code below, i have

Answer 1

Sample Code: To set Footer text programatically

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
      if (e.Row.RowType == DataControlRowType.Footer)
      {
         Label lbl = (Label)e.Row.FindControl("lblTotal");
         lbl.Text = grdTotal.ToString("c");
      }
   }

UPDATED CODE:

  decimal sumFooterValue = 0;
  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
         string sponsorBonus = ((Label)e.Row.FindControl("Label2")).Text;
         string pairingBonus = ((Label)e.Row.FindControl("Label3")).Text;
         string staticBonus = ((Label)e.Row.FindControl("Label4")).Text;
         string leftBonus = ((Label)e.Row.FindControl("Label5")).Text;
         string rightBonus = ((Label)e.Row.FindControl("Label6")).Text;
         decimal totalvalue = Convert.ToDecimal(sponsorBonus) + Convert.ToDecimal(pairingBonus) + Convert.ToDecimal(staticBonus) + Convert.ToDecimal(leftBonus) + Convert.ToDecimal(rightBonus);
         e.Row.Cells[6].Text = totalvalue.ToString();
         sumFooterValue += totalvalue; 
        }

    if (e.Row.RowType == DataControlRowType.Footer)
        {
           Label lbl = (Label)e.Row.FindControl("lblTotal");
           lbl.Text = sumFooterValue.ToString();
        }

   }

protected void gvBill_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)

            Total += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "InvMstAmount"));
        else if (e.Row.RowType == DataControlRowType.Footer)

            e.Row.Cells[7].Text = String.Format("{0:0}", "<b>" + Total + "</b>");

Answer 4

This can be achieved through LINQ with grouping, here a list of items pointed as a data source to the actual grid view. Sample pseudo code which could help coding the actual.

var tabelDetails =(from li in dc.My_table
    join m in dc.Table_One on li.ID equals m.ID
    join c in dc.Table_two on li.OtherID equals c.ID
    where //Condition
group new { m, li, c } by new
{
    m.ID,
    m.Name
} into g
select new
{
    g.Key.ID,
    Name = g.Key.FullName,
    sponsorBonus= g.Where(s => s.c.Name == "sponsorBonus").Count(),
    pairingBonus = g.Where(s => s.c.Name == "pairingBonus").Count(),
    staticBonus = g.Where(s => s.c.Name == "staticBonus").Count(),   
    leftBonus = g.Where(s => s.c.Name == "leftBonus").Count(),  
    rightBonus = g.Where(s => s.c.Name == "rightBonus").Count(),  
    Total = g.Count()  //Row wise Total
}).OrderBy(t => t.Name).ToList();

tabelDetails.Insert(tabelDetails.Count(), new  //This data will be the last row of the grid
{
    Name = "Total",  //Column wise total
    sponsorBonus = tabelDetails.Sum(s => s.sponsorBonus),
    pairingBonus = tabelDetails.Sum(s => s.pairingBonus),
    staticBonus = tabelDetails.Sum(s => s.staticBonus),
    leftBonus = tabelDetails.Sum(s => s.leftBonus),
    rightBonus = tabelDetails.Sum(s => s.rightBonus ),
    Total = tabelDetails.Sum(s => s.Total)
});
