    <p>Ideally you would use an ashx to send XML although I do allow code in an ASPX to intercept normal execution.</p> <pre><code>Response.Clear() </code></pre> <p>I don't use this if you not sure you've dumped anything in the response already the go find it and get rid of it.</p> <pre><code>Response.ContentType = "text/xml" </code></pre> <p>Definitely, a common client will not accept the content as XML without this content type present.</p> <pre><code> Response.Charset = "UTF-8"; </code></pre> <p>Let the response class handle building the content type header properly. Use UTF-8 unless you have a really, really good reason not to.</p> <pre><code>Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetAllowResponseInBrowserHistory(true); </code></pre> <p>If you don't send cache headers some browsers (namely IE) will cache the response, subsequent requests will not necessarily come to the server. You also need to AllowResponseInBrowser if you want this to work over HTTPS (due to yet another bug in IE).</p> <p>To send content of an XmlDocument simply use:</p> <p><strike></p> <pre><code>dom.Save(Response.OutputStream); </code></pre> <p></strike></p> <pre><code>dom.Save(Response.Output); </code></pre> <p>Just be sure the encodings match, (another good reason to use UTF-8).</p> <p>The <code>XmlDocument</code> object will automatically adjust its embedded <code>encoding="..."</code> encoding to that of the <code>Response</code> (e.g. <code>UTF-8</code>)</p> <pre><code>Response.End() </code></pre> <p>If you really have to in an ASPX but its a bit drastic, in an ASHX don't do it.</p>

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).
