    <p>On the master page add the following controls: the hfMsg hidden field will hold the message that will be displayed and the hfCtrl will hold the name of the html control that will display this message which will be in this example lblMsg.</p> <pre><code>&lt;label id="lblMsg" style="background-color:Yellow; border:solid 1px; width:200px;height:100px;display:none;"&gt;&lt;/label&gt; &lt;asp:HiddenField ID="hfMsg" runat="server" /&gt; &lt;asp:HiddenField ID="hfCtrl" runat="server" /&gt; </code></pre> <p>NOTE:you can add another html control with a different id on an ASCX control and use it to display the message instead of the lblMsg.</p> <p>and the following script:</p> <pre><code>&lt;script language="javascript" type="text/javascript"&gt; var msg = $('#&lt;%= hfMsg.ClientID %&gt;').attr("value"); var ctrl = $('#&lt;%= hfCtrl.ClientID %&gt;').attr("value"); if (msg != undefined &amp;&amp; msg != "") { $("#" + ctrl).html(msg); $("#" + ctrl).show(); } else { $("#" + ctrl).hide(); } &lt;/script&gt; </code></pre> <p>NOTE:the script simply checks to see if the hfMsg control has a message to display or not.</p> <p>and add the following two methods to the master page:</p> <pre><code>public void ShowMessage(string control, string message) { this.hfCtrl.Value = control; this.hfMsg.Value = message; } public void ClearMessage() { this.hfMsg.Value = string.Empty; } </code></pre> <p>finally you can call the ShowMessage method from any page like this to display a message on the master page:</p> <pre><code>Master.ShowMessage("lblMsg","hello world!"); </code></pre> <p>and if you have a user control that holds an html label (e.g lblUserMsg) to display the message you can simply call ShowMessage and pass it the name of the label:</p> <pre><code>Master.ShowMessage("lblUserMsg","hello world!"); </code></pre>

    1. COThis is clever, but how can I access **Master** from a user control? I tried this.Page.Master and the VirtualPath line that works for pages, but they don't work on user controls (.ascx.cs).

    2. COyou can create a utility class and add this method to it: public static void ShowMessage(Page p, string msg, string ctrl) { (p.Master.FindControl("hfCtrl") as HiddenField).Value = ctrl; (p.Master.FindControl("hfMsg") as HiddenField).Value = msg; } and call it anywhere. and in the user control call it this way: Util.ShowMessage(this.Page,"message","control");

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).
