I want to Learn MVC pattern with Asp.Net. First of all Basics(how to do Insert,Update,Delete)

 string connectionstring = "Data source=PCNAME; Initial Catalog=Test; Integrated Security=true";
                SqlConnection conn = new SqlConnection(connectionstring);
                conn.Open();
                SqlCommand comm = new SqlCommand("SELECT * from tst111 where studid=1123", conn);
                SqlDataAdapter da = new SqlDataAdapter(comm);
                DataSet ds = new DataSet();
                da.Fill(ds);
                Grd1.DataSource = ds;
                Grd1.DataBind();
  protected void Btsubmit_Click(object sender, EventArgs e)
        {
            SqlConnection conn = new SqlConnection(connectionstring);
            conn.Open();
            SqlCommand comm = new SqlCommand("Insert into StudentEnq values("+ TxtStudId.Text + ",'"+  TxtName.Text + "')",conn);
            int Result=comm.ExecuteNonQuery();
        }

        protected void Submit_Click(object sender, EventArgs e)
        {

            SqlConnection con = new SqlConnection(connectionstring);
            SqlCommand cmd = new SqlCommand("AddStudInfo", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("@StudId", SqlDbType.Int).Value = Convert.ToInt32(TxtStudId.Text);
            cmd.Parameters.Add("@studname", SqlDbType.VarChar, 50).Value = TxtName.Text.ToString();
            con.Open();
            int Result=cmd.ExecuteNonQuery();
            con.Close();
        }

<table>
      <tr>
          <td>
              Student ID
          </td>
          <td>
             <asp:TextBox ID="TxtStudId" runat ="server"></asp:TextBox>

          </td>
      </tr>
      <tr>
          <td colspan="2">
              <asp:Button ID="Btsubmit" runat ="server" Text ="Submit" OnClick="Btsubmit_Click" />
              <asp:Button ID="Submit" runat ="server" Text ="Stored Proc" OnClick="Submit_Click" />
          </td>
      </tr>
