    <p>Well, the first compiler error I get is that it complains that:</p> <blockquote> <p>Using the generic type 'System.Collections.Generic.IEnumerator' requires '1' type arguments</p> </blockquote> <p>This is on line 16, this one:</p> <pre><code>IEnumerator IEnumerable.GetEnumerator() </code></pre> <p>Fixing that by adding a using directive for the <code>System.Collections</code> namespace (tip: place the cursor just after IEnumerator, on the <em>r</em> at the end of the word, and hit Ctrl+. (ctrl + the dot-key), it should suggest you add a "using System.Collections;" directive, do that).</p> <p>Then it compiles, and runs. Does that match what you expect?</p> <p>Also, note that you should always post the actual error messages you're getting, this way we're not barking up the wrong tree if there's something else wrong with your code that we're not seeing at first glance.</p> <p>Additionally, you can simplify this very common implementation of <code>IEnumerable&lt;T&gt;</code> by calling one of the methods from the other, hence I would simplify the implementation of the second methods like this:</p> <pre><code>IEnumerator IEnumerable.GetEnumerator() { return GetEnumerator(); // this will return the one // available through the object reference // ie. "IEnumerator&lt;int&gt; GetEnumerator" } </code></pre> <p>this way you only implement the actual enumerator code once.</p> <p>And finally see <a href="https://stackoverflow.com/users/27423/earwicker">Earwicker</a>'s <a href="https://stackoverflow.com/questions/1174713/ienumerablet-in-c/1174736#1174736">answer</a> as well, it shows a better (in my opinion at least) way to write this whole code.</p>

    1. CO+1. The last part about reusing one implementation of the enumerator on the other is the icing on the cake.

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).
