Body
<p>You can try the following as a demo. Server side DropDownLists are replaced with HTML select elements so that exception "Invalid postback or callback argument" doesn't happen. Drawback in this demo is that the values are not restored on form after postback. You can put this inside a form in Default.aspx:</p> <pre><code><script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script> <script type="text/javascript"> function populate(populateInitial) { $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: '/Default.aspx/populate', data: "{'populateInitial': '" + populateInitial + "'}", dataType: "json", async: false, success: function(result) { var ddlItems = document.getElementById('ddlItems'); ddlItems.options.length = 0; $.each(result.d, function(key, item) { ddlItems.options[key] = new Option(item); }); } }); } </script> <form id="form1" runat="server"> <div> <select id="ddlItems" name="ddlItems"> </select> <br /> <input type="button" onclick="populate('0');" value="Change values" /> <br /> Selected item: <asp:Label ID="lblSelectedItem" runat="server" Text=""> </asp:Label> <br /> <asp:Button ID="Button1" runat="server" Text="Write out selected item text" /> </div> <script type="text/javascript"> populate('1'); </script> </code></pre> <p>And you put these methods inside Default.aspx.cs:</p> <pre><code> protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) { lblSelectedItem.Text = Request["ddlItems"].ToString(); } } [System.Web.Services.WebMethod()] [System.Web.Script.Services.ScriptMethod()] public static List<string> populate(string populateInitial) { if (populateInitial == "1") return (new string[] { "a", "b" }).ToList(); else return (new string[] { "c", "d", "e", "f" }).ToList(); } </code></pre>

Guidance

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.
