using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page

    {

    }

    public class fields
    {
        public string firstname { get; set; }
        public string middlename { get; set; }
        public string lastname { get; set; }
        public string phonenumber { get; set; }

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        List<fields> data = new List<fields>();

        string fn = TextBox1.Text;
        string mn = TextBox3.Text;
        string ln = TextBox2.Text;

Use this:

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

[Serializable]
public class fields
{
    public string firstname { get; set; }
    public string middlename { get; set; }
    public string lastname { get; set; }
    public string phonenumber { get; set; }

}

public partial class _Default : System.Web.UI.Page
{
    List<fields> data = null;

    protected void Page_Load(object sender, EventArgs e)
    {
        data = ViewState["_data"] as List<fields>;
        if (data == null) 
            data = new List<fields>();
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        string fn = TextBox1.Text;
        string mn = TextBox3.Text;
        string ln = TextBox2.Text;
        string pn = TextBox4.Text;

        fields s = new fields();
        s.firstname = TextBox1.Text;
        s.middlename = TextBox3.Text;
        s.lastname = TextBox2.Text;
        s.phonenumber = TextBox4.Text;

        data.Add(s);
        ViewState["_data"] = data;

        GridView1.DataSource = data;
        GridView1.DataBind();
    }
}

Hope it works!

I am getting this error. Type '_Default+fields' in Assembly 'App_Web_3zhqnips, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

You have to mark fields class as Serializable. I have updated the code above. Please check

I don't see any reason for not working! Are you sure you tested my updated code?

Thank you very much for your guidance. I succeed in using your coding. But only one row is persistent all previous rows are deleted. How to do it?
