    <p>C# did not support exception filters like VB does until C# 6. As for how they work, see Eric Lippert's <a href="http://blogs.msdn.com/b/ericlippert/archive/2004/09/01/224064.aspx" rel="nofollow">"Finally" Does Not Mean "Immediately"</a></p> <p>Starting in C# 6, exception filters are supported, as <a href="https://blogs.msdn.microsoft.com/csharpfaq/2014/11/20/new-features-in-c-6/" rel="nofollow">the C# FAQ demonstrates</a>:</p> <pre><code>try { … } catch (MyException e) when (myfilter(e)) { … } </code></pre> <blockquote> <p>If the parenthesized expression after ‘if’ [now <code>when</code>] evaluates to true, the catch block is run, otherwise the exception keeps going.</p> <p>Exception filters are preferable to catching and rethrowing because they leave the stack unharmed. If the exception later causes the stack to be dumped, you can see where it originally came from, rather than just the last place it was rethrown.</p> <p>It is also a common and accepted form of “abuse” to use exception filters for side effects; e.g. logging. They can inspect an exception “flying by” without intercepting its course. In those cases, the filter will often be a call to a false-returning helper function which executes the side effects:</p> </blockquote> <pre><code>private static bool Log(Exception e) { /* log it */ ; return false; } … try { … } catch (Exception e) when (Log(e)) {} </code></pre> <p>Thanks to <a href="https://stackoverflow.com/users/5962841/mafii">Mafii</a> for the link to the C# 6 documentation.</p>

    1. COOkay, so filter is basically just an if statement and if it is not met it rethrows it?

    2. CONo it's subtly different since a real filter doesn't even catch it if it decides to handle the exception, whereas a workaround with an if catches and re-throws it. This has slightly different semantics related to stack-unrolling.

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.

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