AJAX PopupControl Extender to Display Row Details with Gridview

Hi all ,

try this example to use AJAX PopupControl Extender to Display Row Details with Gridview

Step1 :- create a new website and add new web page

Step2 :- in Web page drag ScriptManager , Gridview , AJAX Popup Extender and Panel control from toolbox

so your page will be like this

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<!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">
    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
           BorderColor="#336699" BorderStyle="Solid" BorderWidth="1px"
           CellPadding="3" Font-Names="Verdana" Font-Size="10pt"
              <asp:BoundField DataField="ProductID" HeaderText="Product ID" />
              <asp:BoundField DataField="ProductName" HeaderText="Product Name" />
              <asp:TemplateField ItemStyle-Width="40" ItemStyle-HorizontalAlign="Right">
                    <asp:Image ID="Image1" runat="server" ImageUrl="~/page_topic_magnify.png" />
                    <cc1:PopupControlExtender ID="PopupControlExtender1" runat="server"
                       DynamicContextKey='<%# Eval("ProductID") %>'
                       DynamicServiceMethod="GetDynamicContent" Position="Bottom">
                    <asp:Panel ID="Panel1" runat="server"> </asp:Panel>
           <HeaderStyle BackColor="#336699" ForeColor="White" />

Step3 :- in code behind add the following code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using AjaxControlToolkit;
using System.Text;

public partial class _Default : System.Web.UI.Page
    private void LoadData()
        string constr = "Data Source=.;Initial Catalog=Northwind;Integrated Security=True";
        string query = "SELECT ProductID, ProductName FROM Products";
        SqlDataAdapter da = new SqlDataAdapter(query, constr);
        DataTable table = new DataTable();
        GridView1.DataSource = table;

    protected void Page_Load(object sender, EventArgs e)
        if (!Page.IsPostBack)

    protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        if (e.Row.RowType == DataControlRowType.DataRow)
            PopupControlExtender pce = e.Row.FindControl("PopupControlExtender1") as PopupControlExtender;
            string behaviorID = "pce_" + e.Row.RowIndex;
            pce.BehaviorID = behaviorID;
            Image img = (Image)e.Row.FindControl("Image1");
            string OnMouseOverScript = string.Format("$find('{0}').showPopup();", behaviorID);
            string OnMouseOutScript = string.Format("$find('{0}').hidePopup();", behaviorID);
            img.Attributes.Add("onmouseover", OnMouseOverScript);
            img.Attributes.Add("onmouseout", OnMouseOutScript);

            //e.Row.Attributes.Add("onmouseover", OnMouseOverScript);
            //e.Row.Attributes.Add("onmouseout", OnMouseOutScript);

    [System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
    public static string GetDynamicContent(string contextKey)
        string constr = "Data Source=.;Initial Catalog=Northwind;Integrated Security=True";
        string query = "SELECT UnitPrice, UnitsInStock,UnitsOnOrder FROM Products WHERE ProductID = " + contextKey;
        SqlDataAdapter da = new SqlDataAdapter(query, constr);
        DataTable table = new DataTable();
        StringBuilder b = new StringBuilder();
        b.Append("<table style='background-color:#f3f3f3; border: #336699 3px solid; ");
        b.Append("width:350px; font-size:10pt; font-family:Verdana;' cellspacing='0' cellpadding='3'>");
        b.Append("<tr><td colspan='3' style='background-color:#336699; color:white;'>");
        b.Append("<b>Product Details</b>"); b.Append("</td></tr>");
        b.Append("<tr><td style='width:80px;'><b>Unit Price</b></td>");
        b.Append("<td style='width:80px;'><b>Stock</b></td>");
        b.Append("<td><b>Units On Order</b></td></tr>");
        b.Append("<td>$" + table.Rows[0]["UnitPrice"].ToString() + "</td>");
        b.Append("<td>" + table.Rows[0]["UnitsInStock"].ToString() + "</td>");
        b.Append("<td>" + table.Rows[0]["UnitsOnOrder"].ToString() + "</td>");
        return b.ToString();

Hope this helps

Good Luck

    I am also getting web service call failed 500 error. I have tested the webservice in browser and it works by itself. When I replace the: string.Format(“$find(‘{0}’).showPopup();”, behaviorID); with a simple alert – the error is gone – although it does not show popup obviously. Can you explain what $find does and anything else it needs to work which I might have left out?
