    <p>So on my ASP.NET solution's default page, I have a SlideShowExtender object, linked to a WebMethod which retrieves slides from an MSSQL database. Through debugging I can confirm that Slide objects are successfully created from said database, but once the page has loaded the SlideShow element does nothing.</p> <p>Below is my code; I appreciate in advance any responses received. Thank you.</p> <p><strong>Edit:</strong> I forgot to mention that I've have verified the integrity of the Image URLs; they're correct.</p> <p><strong>Default.aspx (Default.aspx.cs is just a standard code-behind with an empty Page_Load method):</strong></p> <pre><code>&lt;%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Dissertation._Default" %&gt; &lt;%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %&gt; &lt;asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"&gt; &lt;/asp:Content&gt; &lt;asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"&gt; &lt;asp:ToolkitScriptManager ID="scrptman" runat="server"&gt;&lt;/asp:ToolkitScriptManager&gt; &lt;asp:Image ID="imgBanner" Width="800" Height="300" runat="server"/&gt; &lt;br /&gt; &lt;asp:Label ID="lblDesc" runat="server"&gt;&lt;/asp:Label&gt; &lt;asp:SlideShowExtender ID="sldShow" runat="server" TargetControlID="imgBanner" SlideShowServicePath="~/BannerImages.asmx" SlideShowServiceMethod="GetPhotos" AutoPlay="true" ImageDescriptionLabelID="lblDesc" Loop="true" /&gt; &lt;/asp:Content&gt; </code></pre> <p><strong>BannerImages.asmx.cs</strong></p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; using System.Data.SqlClient; using System.Configuration; using AjaxControlToolkit; namespace Dissertation { /// &lt;summary&gt; /// Summary description for BannerImages /// &lt;/summary&gt; /// [System.Web.Script.Services.ScriptService] [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] public class BannerImages : System.Web.Services.WebService { [WebMethod] [System.Web.Script.Services.ScriptMethod] public Slide[] GetPhotos() { List&lt;Slide&gt; images = new List&lt;Slide&gt;(); ConnectionStringSettings settings = System.Configuration.ConfigurationManager.ConnectionStrings["Database"]; SqlConnection conn = new SqlConnection(settings.ConnectionString); SqlCommand cmd = new SqlCommand("Select * from sol_bannerData", conn); SqlDataReader read = null; try { conn.Open(); read = cmd.ExecuteReader(); while(read.Read()) { images.Add(new Slide(Server.MapPath("~/cms/uploads/banners/" + read["ImageURL"].ToString()), "", read["Description"].ToString())); } } catch(SqlException err) { images.Clear(); images.Add(new Slide("", "", "Images could not be loaded: " + err.Message)); return images.ToArray(); } finally { if(read != null) read.Close(); if(conn != null) conn.Close(); } Slide[] toReturn = images.ToArray(); return toReturn; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
