protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
      int newIndex = e.NewSelectedIndex;//Row that the user is selecting(!e is a parameter)
      object EventID = GridView1.DataKeys[newIndex].Value;
      object stadiumID = GridView1.DataKeys[newIndex].Value;
          string Game = GridView1.Rows[newIndex].Cells[0].Text;
      string Location = GridView1.Rows[newIndex].Cells[1].Text;
      string Stadium = GridView1.Rows[newIndex].Cells[2].Text;
      string Date = GridView1.Rows[newIndex].Cells[3].Text;
      string Hour = GridView1.Rows[newIndex].Cells[4].Text;
      Session["data"]= string.Format("Event:{0}<br />Location:{1}<br />Stadium name:{2}<br />Date:{3}", Game, Location, Stadium, Date);
      Session["StadeID"] = stadiumID;
      Session["EventID"] = EventID;
