    <p>I am trying to write a page to host on and the code keeps throwing an exception. I believe that the problem is that the permissions on the server will not let the subclass of XmlUrlResolver get instantiated, but I'd love some help with this please...</p> <p>This code does work on my local dev box, and if I use File.ReadAllText(HostingEnvironment.MapPath("~/xml/home.xml")) it does work, so I am fairly certain it's not IO permissions....</p> <p>Exception:</p> <pre><code> Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

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).
