asp.net grid view render html table. So when you use javascript then you should travase html table. The following code spinet will help you to understand the process.

ASP.NET

<head runat="server">
    <title></title>
    <script src="jquery.min.js"></script>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:gridview id="gv" showheader="false" runat="server" autogeneratecolumns="False" name="grdData" xmlns:asp="#unknown">
                <columns>
                    <asp:templatefield>
                        <itemtemplate>
                            <asp:image id="imgPicPath" runat="Server" alternatetext="Missing" imageurl="<%# Eval("pictpath") %>" />
                        </itemtemplate>
                    
                    <asp:templatefield>
                        <itemtemplate>
                            <asp:label id="lblUserName" runat="server" text="<%# Eval("username") %>" />
                        </itemtemplate>
                    
                     <asp:templatefield>
                        <itemtemplate>
                            <asp:label id="lblUserId" runat="server" text="<%# Eval("Id") %>" />
                        </itemtemplate>
                    
                </columns>            
        </div>
        <input type="button" id="btnShow" value="show" onclick="showGrid();"/>
    </form>
    </script>
</body>

JavaScript

function showGrid() {
           var tbl = $("[id$=gv]");
           var rows = tbl.find('tr');
           for (var index = 0; index < rows.length; index++) {
               var row = rows[index];

               var image = $(row).find("img");
               var userName = $(row).find("[id*=lblUserName]").text();
               var userId = $(row).find("[id*=lblUserId]").text();

               alert(userName + " - " +  userId);
           }
       }

</script>

C#

public partial class Index : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!base.IsPostBack)
            {
                gv.DataSource = GetData();
                gv.DataBind();
            }
        }

        IList<userinfo> GetData()
        {
            return new List<userinfo>
                {
                    new UserInfo{username = "A", pictpath = "a.jpg", Id = "111"},
                    new UserInfo{username = "B", pictpath = "b.jpg", Id = "222"},
                    new UserInfo{username = "C", pictpath = "c.jpg", Id = "333"},
                };
        }
    }
    public class  UserInfo
    {
        public string username { get; set; }
        public string pictpath { get; set; }
        public string Id { get; set; }
    }

why did you have to resurrect such an old question? could you have not just asked a new 1 instead?
