    <p>I have a Dojo Grid with a date column. Despite using a custom formatter, it always does a string sort. Note that my incoming dates will be formatted as 02/17/2005 and I cannot change that.</p> <pre><code>formatDate = function(d){ return dojo.date.locale.format(new Date(d), {datePattern: "M/dd/yyyy", formatLength: 'short', selector: "date"}); } var myData= [ {field: "transactionDate", name: "Transaction Date", width: "115px", datatype: "date", formatter: formatDate }, {field: "description", name: "Transaction Description", width: "170px" }, ]]; var storeData = { items: [ { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"02/15/2010", description:"A description of the transaction" } , { transactionDate:"01/15/2011", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"09/15/2009", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } , { transactionDate:"04/15/2011", description:"A description of the transaction" } ]}; </code></pre> <hr> <pre><code> &lt;div class="claro" style="width: 835px; height: 300px;"&gt; &lt;div dojotype="dojo.data.ItemFileReadStore" jsID="dataStoreForGrid" data="storeData"&gt;&lt;/div&gt; &lt;div id="grid" dojotype="dojox.grid.DataGrid" store="transferStoreForGrid" clientSort="true" jsID="SomeId" structure="myData" rowsperpage="40" &gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <hr> <p>Per Peller's suggestion, I tried formatting as ISO date. Thais had no affect on sorting:</p> <pre><code> formatDate = function(d){ var d2 = dojo.date.stamp.fromISOString(ISODateString(new Date(d))); return dojo.date.locale.format(d2, {selector: 'date', formatLength: 'long'}); } function ISODateString(d) { function pad(n){ return n&amp;lt;10 ? '0'+n : n } return d.getUTCFullYear()+'-' + pad(d.getUTCMonth()+1)+'-' + pad(d.getUTCDate())+'T' + pad(d.getUTCHours())+':' + pad(d.getUTCMinutes())+':' + pad(d.getUTCSeconds())+'Z' } </code></pre>

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.
