    <p>I solved my issue.</p> <p>I added an event to handle the sorting. The event grabs the command name (Data column) and passes it and the sorting direction into a function which will make another call to the database sort the returned results and rebind to the List View.</p> <p>I had to create a view state to hold the List View Sort Direction because for some reason, the onsorting event handler kept saying that the sort direction was ascending.</p> <p><strong>Front End</strong></p> <pre><code>&lt;asp:ListView ID="ContactsListView" OnSorting="ContactsListView_Sorting" runat="server"&gt; &lt;LayoutTemplate&gt; &lt;table width="640px" runat="server"&gt; &lt;tr class="header" align="center" runat="server"&gt; &lt;td&gt; &lt;asp:LinkButton runat="server" ID="SortByFirstNameButton" CommandName="Sort" Text="First Name" CommandArgument="FirstName" /&gt; &lt;/LayoutTemplate&gt; .... &lt;/asp:ListView&gt; </code></pre> <p><strong>Back End</strong></p> <pre><code>protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { BindContacts(string.Empty); } } protected SortDirection ListViewSortDirection { get { if (ViewState["sortDirection"] == null) ViewState["sortDirection"] = SortDirection.Ascending; return (SortDirection)ViewState["sortDirection"]; } set { ViewState["sortDirection"] = value; } } protected void ContactsListView_Sorting(Object sender, ListViewSortEventArgs e) { BindContacts(e.SortExpression + " " + ListViewSortDirection.ToString()); // Check the sort direction to set the image URL accordingly. string imgUrl; if (ListViewSortDirection == SortDirection.Ascending) ListViewSortDirection = SortDirection.Descending; else ListViewSortDirection = SortDirection.Ascending; } private void BindContacts(string sortExpression) { sortExpression = sortExpression.Replace("Ascending", "ASC"); sortExpression = sortExpression.Replace("Descending", "DESC"); using (SqlConnection conn = new SqlConnection(_connStr)) { conn.Open(); using (SqlDataAdapter dAd = new SqlDataAdapter("SELECT * FROM Customer", conn)) { DataTable dTable = new DataTable(); dAd.Fill(dTable); // Sort now dTable.DefaultView.Sort = sortExpression; // Bind data now ContactsListView.DataSource = dTable; ContactsListView.DataBind(); } conn.Close(); } } </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.

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