    <p>Hi I'm new to javascript and dojo. I'm trying to use two dijit DateTextBoxes with the drop-down calendars to establish a date range for a query on a database. I want to restrict the dates available, once the begin or end date has been selected, so that its impossible to pick an end date that is chronologically before the begin date, and vice versa. I'm trying to apply the example called 'changing constraints on the fly' (about half way down the page) from the dojo reference here: <a href="http://dojotoolkit.org/reference-guide/dijit/form/DateTextBox.html" rel="nofollow">http://dojotoolkit.org/reference-guide/dijit/form/DateTextBox.html</a> However, the constraints aren't working in my code. The only thing I'm really doing differently is using the<code>tundra</code> theme. Any suggestions would be greatly appreciated. </p> <p><div class="snippet" data-lang="js" data-hide="false"> <div class="snippet-code"> <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;&lt;/title&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt; &lt;link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.6/dojo/resources/dojo.css"&gt; &lt;link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.6.0/dijit/themes/tundra/tundra.css" media="screen" /&gt; &lt;script src="http://ajax.googleapis.com/ajax/libs/dojo/1.6.0/dojo/dojo.xd.js" data-dojo-config="isDebug: true, parseOnLoad: true"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; dojo.require("dijit.form.DateTextBox"); &lt;/script&gt; &lt;/head&gt; &lt;body class="tundra"&gt; &lt;div&gt; &lt;label for="fromDate"&gt;From:&lt;/label&gt; &lt;input id="fromDate" type="text" name="fromDate" data-dojo-type="dijit.form.DateTextBox" required="true" onChange="dijit.byId('toDate').constraints.min = arguments[0];" /&gt; &lt;label for="toDate"&gt;To:&lt;/label&gt; &lt;input id="toDate" type="text" name="toDate" data-dojo-type="dijit.form.DateTextBox" required="true" onChange="dijit.byId('fromDate').constraints.max = arguments[0];" /&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt;</code></pre> </div> </div> </p>

    1. COThe only other thing I can think of is that each DateTextBox is operating within its own execution context, so they don't 'see' each other.

    2. COThanks for your response Michael! I tried your suggestion, but without any luck. And I don't understand why the constraint isn't being set, even when I hard-code a date like you suggested. Also, my guess is that 'arguments[0]' is the first value in the arguments property of each DateTextBox object, which is updated if the user selects a date; which then would be a valid js date.

Querying!

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.
