Body
It's been two weeks since I asked this question, and I am assuming that nobody will answer, so for the record, I will post how I actually solved this problem. <ol> <li>I changed from using an html Table to using an Unordered list. (an option that I had previously ignored because of my perceived difficulty in styling the <code><UL></code>.</li> <li>I added two hidden fields, one to trigger whether or not the event had fired, and one to store the selected value.</li> </ol> <code><asp:HiddenField runat="server" ID="hidSelectionChanged" Value="false"/></code> <code><asp:HiddenField runat="server" ID="hidSelectionValue" Value=""/></code> I created the "change" event as follows: <pre><code>function onchange(param) { var chg = document.getElementById('<%=hidSelectionChanged.ClientID%>'); var val = document.getElementById('<%=hidSelectionValue.ClientID%>'); if (chg) { chg.value = 'true'; } if (val) { val.value = param; } __doPostBack('pnlResults', ''); } </code></pre> Then in each <code>LI</code> of the <code>UL</code> I had this code: <pre><code><li class="ddl_li"><a href="javascript:onchange('Summary_1')">Summary</a></li> </code></pre> The result was a full page post-back, but in the <code>Page_Load</code> event of the Page, I could now check <code>hidSelectionChanged.Value</code> to see if the PostBack was triggered by my dropdown, and I could check <code>hidSelectionValue.Value</code> to get the selected value. In the end, all worked out well.

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.
