        SqlCommand com;

        protected void btn_show_Click(object sender, EventArgs e)
        {
            DataSet reportData = new DataSet();
            reportData.ReadXml(Server.MapPath("student.xml"));
            GridView1.DataSource = reportData;
            GridView1.DataBind();
        }

        protected void btn_insert_Click(object sender, EventArgs e)
        {
            foreach (GridViewRow g1 in GridView1.Rows)
            {
                SqlConnection con = new SqlConnection(connStr);
                com = new SqlCommand("insert into student(sid,sname,smarks,saddress) values ('" + g1.Cells[0].Text + "','" + g1.Cells[1].Text + "','" + g1.Cells[2].Text + "','" + g1.Cells[3].Text + "')", con);
                con.Open();
                com.ExecuteNonQuery();
                con.Close();

            }
            Label1.Text = "Records inserted successfully";
        }
    }
}


One more Help in this..
Tables 
student(sid,sname,smarks,saddress) //Here we insert from XML to DB
master_table(sid,sname,age,gender) these r the two tables
Here i want to check one more thing, i.e., if sid in XML file is not in the master_table means then i want to show those in different colour in the grid view while i click the show button.
