Retrieve data into DataGridView in ASP.NET

hi
try like this:

it just a sample

in aspx:



in .cs:

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

public partial class Default8 : System.Web.UI.Page
{
    string connStr = ConfigurationManager.ConnectionStrings["ConStr"].ToString();
    protected void Page_Load(object sender, EventArgs e)
    {
        bind();
    }
    private void bind()
    {
        SqlConnection conn = new SqlConnection(connStr);
        SqlDataAdapter da = new SqlDataAdapter("Select * from Movie", conn);
        DataSet ds = new DataSet();
        da.Fill(ds);
        dgvMovie.DataSource=ds.Tables[0];
        dgvMovie.DataBind();

    }

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        bind();
    }
}

here i create a separate method for gird binding and call in page load and button click so it will bind the record when you submit.
