No change to the aspx UI page. I just modified the code behind page. Please have look in the RowDataBound method.

C#

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

public partial class Demo : System.Web.UI.Page
{
    List<user> userList = new List<user>();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            userList.Add(new User() { UserName = "Alex" });
            userList.Add(new User() { UserName = "Bob" });
            userList.Add(new User() { UserName = "Jeniffer" });
            GridView1.DataSource = userList;
            GridView1.DataBind();
        }

    }

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton link = e.Row.FindControl("LinkButton1") as LinkButton;
            string name = e.Row.Cells[0].Text;
            link.Attributes["onclick"] = "return popwin('" + name + "')";
        }
    }
}

public class User
{
    public string UserName  { get; set; }
}
