Hi Riccardo,<br>
<br>
here a code snippet I have in use:<br>
<br>
<tt>myStore.setDefaultSort('magnitudo', 'DESC'); // just after
instanciating the store</tt><br>
<br>
Best regards,<br>

<div>I have a problem: I'm not able to set correctly the sortInfo
to have my data ordered in my GridPanel by a column.</div>
<div>I've spent lot of time by forum but I was not able to find a
solution for me.</div>
<div>I load a WFS layer from MapServer/Postgis, then I like order
the data (like 20-30 records) by date field.</div>
<div>My date field originally come from Postgres "timestamp", but
here I translate it as string.</div>
<div>Anyway I don't know why Ext order my records with this column
"full_date", in ascending order, and I'm not able to reverse
this order, or better change the field to use for order my data
(like "magnitudo", that is a double field).</div>
<div><br>
</div>
<div>I use Ext 3.4.0, and I try my page on Chrome.</div>
