    <p>I built a Menu Bar to my site master in ASP.net:</p> <pre><code>&lt;div class="MenuBar"&gt; &lt;asp:ContentPlaceHolder ID="MainContent" runat="server"&gt; &lt;asp:Menu ID="menuBar" runat="server" Orientation="Vertical" Width="100%"&gt; &lt;DynamicHoverStyle CssClass="DynamicHover" /&gt; &lt;DynamicMenuItemStyle CssClass="DynamicMenuItem" /&gt; &lt;DynamicSelectedStyle CssClass="DynamicHover" /&gt; &lt;StaticHoverStyle CssClass="staticHover" /&gt; &lt;StaticMenuItemStyle CssClass="StaticMenuItem" ItemSpacing="1px" /&gt; &lt;StaticSelectedStyle CssClass="staticHover" /&gt; &lt;/asp:Menu&gt; &lt;/asp:ContentPlaceHolder&gt; &lt;/div&gt; </code></pre> <p>Code behind:</p> <pre><code>public partial class SiteMaster : System.Web.UI.MasterPage { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { getMenu(); } } private void getMenu() { Menu menuBar = new Menu(); SqlConnection con = new SqlConnection(); con.ConnectionString = "server=(local);database=PhilipsMaterials;Integrated Security=SSPI;"; con.Open(); DataSet ds = new DataSet(); DataTable dt = new DataTable(); string sql = "Select [Material Name] from Materials"; SqlDataAdapter da = new SqlDataAdapter(sql, con); da.Fill(ds); dt = ds.Tables[0]; DataRow[] drowpar = dt.Select(); String s = "sss"; foreach (DataRow dr in drowpar) { menuBar.Items.Add(new MenuItem(dr["Material Name"].ToString())); } con.Close(); } </code></pre> <p>}</p> <p>For some reason the menu is not being displayed when I view the site on the browser. Someone knows why? Thanks.</p>

    1. CORemove this - Menu menuBar = new Menu(); you are creating a new Menu rather than using the one in your markup directly

    3. COThen you have a problem with the link between the markup and your code behind - check the definition at the top of your MasterPage (in particular the Inherits and CodeBehind attributes) are correct

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.

SQuiL has stopped working due to an internal error.

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