Not the best piece of code in the world, but, you can have a look at the following simple implementation and follow a similar approach:

Note : Pardon the C# code. I don't know VB.NET and you have to convert these codes to VB.NET to run

Aspx:

XML

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <div>
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
                Width="215px" OnRowCommand="GridView1_RowCommand"
                onrowdatabound="GridView1_RowDataBound">
                <Columns>
                    <asp:BoundField DataField="Name" HeaderText="Name" />
                    <asp:TemplateField ShowHeader="False">
                        <ItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"
                                CommandName="Edit" Text="Edit"></asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>
        </div>
    </div>
    </form>
</body>
</html>

And, CodeBehind (Written in C# as I do not know VB.net, please convert into VB.NET)

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

public partial class _Default : System.Web.UI.Page
{
    //A simple Person class
    public class Person
    {
        public int Id
        {
            get;
            set;
        }
        public string Name
        {
            get;
            set;
        }
        public Person(int Id, string Name)
        {
            this.Id = Id;
            this.Name = Name;
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            //Populating some dummy data in the GridView. In reality, you should populate these from the database
            IList items = new ArrayList();

            items.Add(new Person(1, "Peter"));
            items.Add(new Person(2, "John"));
            items.Add(new Person(3, "Shubho"));

            GridView1.DataSource = items;
            GridView1.DataBind();
        }
    }
   
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Edit")
        {
            //User clicked Edit link
            int userId = Convert.ToInt32(e.CommandArgument);

             //Redirect to your create page here. In the CreateUser.aspx, load the user with the supplied userId from the database and populate user data in the text box

            Response.Redirect(string.Format("CreateUser.aspx?Id={0}",userId));
           
        }
    }

     protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
     {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton link = e.Row.FindControl("LinkButton1") as LinkButton;
            if (link != null)
            {
                //Set the CommandArgument to Person's Id for the Link buttons so that, when user clicks the Edit link, the Id value can be retrieved from the CommandArgument
                link.CommandArgument = ((Person)e.Row.DataItem).Id.ToString();
            }
        }
    } 
}

I provided you the codes because somehow I feel you are kind of new in Asp.net and thought this will help you.
