    <p>I'm quite new to ASP.NET and C# and I'm having some issues with my routing. Was hoping someone would be so kind to help me out.</p> <p>A user is supposed to give 3 parameters (<code>string</code>, <code>bool</code>, <code>bool</code>). So I have a small form on my index page:</p> <pre><code> &lt;% using (Html.BeginForm("search", "Home")) { %&gt; &lt;label &gt;Name: &lt;/label&gt;&lt;br /&gt; &lt;input type="text" id='ml' name='ml' /&gt;&lt;br /&gt; &lt;label &gt;Sort members alphabethic? &lt;/label&gt; &lt;input type="checkbox" id='sortalph' name='sortalph' /&gt;&lt;br /&gt; &lt;label &gt;Number the list? &lt;/label&gt;&lt;input type="checkbox" id='number' name='number' /&gt;&lt;br /&gt; &lt;input type="submit" value='Submit'/&gt; &lt;% } %&gt; </code></pre> <p><code>Global.asax.cs</code> is set up like this:</p> <pre><code> routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index"} // Parameter defaults ); routes.MapRoute( "Search", // Route name "{controller}/{action}/{ml}/{sortalph}/{number}", // URL with parameters new { controller = "Docent", action = "Search" } // Parameter defaults ); </code></pre> <p>The start of the <code>Search</code> method in my <code>HomeController</code> looks like this:</p> <pre><code>public ActionResult Search(string ml, bool? sortalph, bool? number) { if (sortalph == null) { sortalph = false; } if (number == null) { number = false; } </code></pre> <p>When I debug <strong><code>sortalph</code> and <code>number</code> are always <code>null</code></strong>. I'm not sure why.</p>

    1. COJust curious: why do you use nullables?

    2. CO@dan, I use nullables frequently too, so that I can distinguish between a clean url/post with the parameter missing (and thus use a default that could be 'true') and when it was actually passed deliberately 'false' or '0' without having to consult the valueprovider

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).
