    <p>First of all you uses <a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow noreferrer">$.ajax</a> which don't know the <code>dataType: 'xmlstring'</code>. You means <code>dataType: 'xml'</code>.</p> <p>Second You misunderstood the <code>datatype: 'xmlstring'</code>. Instead of the usage of separate <code>$.ajax</code> call you can use</p> <pre><code>datatype: 'xml', url: 'register.php', postData: {uID: uID}, </code></pre> <p>options of jqGrid. You can consider to implement <code>uID</code> property of the <code>postData</code> as method (see <a href="https://stackoverflow.com/a/2928819/315935">here</a> for details). The body of <code>setInterval</code> can be reduced to the call of <code>$("#tasks").trigger('reloadGrid', [{current: true}]);</code> (see <a href="https://stackoverflow.com/a/5297156/315935">here</a> and <a href="https://stackoverflow.com/a/3808014/315935">here</a>).</p> <p>If you need don't load the grid body at the first and do loading only inside of <code>setInterval</code> you can set <code>datatype: 'local'</code> and change <code>datatype</code> to <code>'xml'</code> with respect of <code>setGridParam</code> like you do already.</p> <p>Moreover I don't use PHP myself, but nevertheless I would recommend you to use <code>DOMDocument</code> from <a href="http://www.php.net/manual/en/book.dom.php" rel="nofollow noreferrer">PHP DOM</a> (see for example <a href="http://www.tonymarston.net/php-mysql/dom.html" rel="nofollow noreferrer">here</a> or <a href="http://www.ibm.com/developerworks/library/os-xmldomphp/" rel="nofollow noreferrer">here</a> for details) instead of writing the XML manually. Direct construction of XML text can produce many errors. For example you can't place characters like <code>&lt;</code> directly as the content of XML elements without its encoding. At least <a href="http://www.w3schools.com/xml/xml_cdata.asp" rel="nofollow noreferrer">CDATA</a> sections should be used.</p>

    1. COwow ok thanks a lot for all the info but after following most of that(except php to XML) ...I am still stuck with the original problem, the grid does not refresh every x seconds with the new records. I will post the code if you need it.

    2. CO@user1160022: You are welcome! To be able to help you to localize the problem I need of course the current code which you use. Moreover if could be important to know where you defines (or assign) the `uID`. If would be good if you post the XML response which will be produced by the server.

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).
