<asp:GridView ID="GridView1" runat="server">
</asp:GridView>

protected void Page_Load(object sender, EventArgs e) {
    if (!IsPostBack) {
        bindData();   
    }
}

public void bindData() {
        SqlConnection con=new SqlCponnection(ConnectionStrings);
        SqlDataAdapter da = new SqlDataAdapter("select * from  Your TableName", con);
        DataSet ds = new DataSet();
        try {
            da.Fill(ds, "YourTableName");
            GridView1.DataSource = ds;
            GridView1.DataBind();
        } catch (Exception e) {
           Response.Write( e.Message);
        } finally {
            ds.Dispose();
            da.Dispose();
            con.Dispose();
        }
