In the following code...i am not being able to set the commandtype as storedprocedure.i have commented out that line.
Its the back end coding of an asp.net 3.5 page with c#.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

public partial class NEWRECORD : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
string conn = "Data Source=.;Initial Catalog=School;Integrated Security=True";
SqlConnection con=new SqlConnection(conn);
con.Open();
SqlCommand cmd=new SqlCommand();
// cmd.CommandType=
cmd.Connection = con;

cmd.CommandText = "NEWREC";
int roll;
roll=Convert.ToInt16(TextBox1.Text);
int klass;
klass=Convert.ToInt16(TextBox3.Text);

cmd.Parameters.Add(new SqlParameter("@id",1));
cmd.Parameters.Add(new SqlParameter("@name",TextBox2.Text));
cmd.Parameters.Add(new SqlParameter("@class", klass));
cmd.ExecuteNonQuery();
con.Close();
}
}
