<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucProduct.ascx.cs" Inherits="jQueryPOC.UserControls.ucProduct" %>

                <asp:ImageMap ID="imgProduct" runat="server" ImageUrl='<%# Eval("ImageName") %>'>
                </asp:ImageMap>

        </div>
    </ItemTemplate>
</asp:DataList>
</div>
<div id="dvDetails" style="float: left; width: 20%;display:none; border:1px;">
</div>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetProducts"
    TypeName="jQueryPOC.UserControls.ucProduct"></asp:ObjectDataSource>

ucProduct.ascx.cs

 public IList<ProductDO> GetProducts()
        {
            IList<ProductDO> products = new List<ProductDO>();
            products.Add(new ProductDO { ProductID = 1, ProductName = "Samsung Galaxy S3", Price = 36000, ImageName = "http://localhost:58445/images/SGS3.jpg" });
            products.Add(new ProductDO { ProductID = 2, ProductName = "Apple iPhone 4", Price = 35000, ImageName = "http://localhost:58445/images/AiP4.jpg" });
            products.Add(new ProductDO { ProductID = 3, ProductName = "Samsung Galaxy Note", Price = 32000, ImageName = "http://localhost:58445/images/SGN.jpg" });
            return products;
        }

Page method to get UserControl

[WebMethod]
        public static string LoadUserControl()
        {
            using (Page page = new Page())
            {
                HtmlForm form = new HtmlForm();
                UserControl userControl = (UserControl)page.LoadControl("UserControls/ucProduct.ascx");
                form.Controls.Add(userControl);
                using (StringWriter writer = new StringWriter())
                {
                    page.Controls.Add(form);
                    HttpContext.Current.Server.Execute(page, writer, false);
                    return writer.ToString();
                }
            }
        }

But remember you will not be having any viewstate for this usercontrol. So in case you have any button on this UserControl and you want to perform some action on this button then everything should be taken care by means of client scripts. In this case you will have to submit your form through AJAX using jQuery or other client libraries..
