    <p>I'm working on a website with different pages, but all loaded once, so no rest calls anymore, except for ajax fetching data, not for new pages.</p> <p>I'm not that familiour with dojo, so I guess that this approach is good (please correct me if I'm wrong):</p> <p>Make a menu and a stackContainer containing each page as a contentPane. Since I don't want to put all my code and layout in index.html, I decided to create a custom widget for every page. On one page, I want to put a datagrid, so my customWidget has a declarative container for a datagrid, which is filled up with data by an ajax-call. </p> <p>Problem is: my datagrid is created, but not visible when I go to that contentPane of my stackContainer.</p> <pre><code>&lt;div id="menu" data-dojo-type="dijit/Menu"&gt; &lt;div id="first_page_menu" data-dojo-type="dijit/MenuItem"&gt;First page&lt;/div&gt; &lt;div id="second_page_menu" data-dojo-type="dijit/MenuItem"&gt;Second page&lt;/div&gt; &lt;/div&gt; &lt;div data-dojo-type="dijit/layout/StackContainer" id="stackContainer"&gt; &lt;div data-dojo-type="dijit/layout/ContentPane" title="first page" id="first_page_cp"&gt; content &lt;/div&gt; &lt;div data-dojo-type="dijit/layout/ContentPane" title="second page" id="second_page_cp"&gt; &lt;div data-dojo-type='myWidget/pageWithDatagrid'&gt;&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;script&gt; require([ "dojo/dom", "dijit/registry", "dijit/Menu", "dijit/MenuItem", "dojo/parser", "dojo/ready", "dijit/form/Button", "dijit/form/TextBox", "myWidget/pageWithDatagrid", "dijit/form/DateTextBox", "dojo/date/locale", "dijit/layout/StackContainer", "dijit/layout/StackController", "dijit/layout/ContentPane" ], function(dom, registry, Menu, MenuItem, parser, ready, Button, TextBox, pageWithDatagrid){ var showPage = function(event){ var cpId = event.target.id.replace('menu_text','cp'); var stackContainer = registry.byId('stackContainer'); stackContainer.selectChild(cpId); }; // Register click on menu to show corresponding page in stackcontainer var registerMenuHandlers = function(){ var stackContainer = registry.byId('stackContainer'); dojo.forEach(stackContainer.getChildren(), function(menu){ registry.byId(menu.id.replace('contentpane','menu')).on('click', showPage); }); }; parser.parse(); ready(function(){ registerMenuHandlers(); }); }); </code></pre> <p>This is my pageWithDatagrid.js:</p> <pre><code>define([ "dojo/_base/declare", "dijit/_WidgetBase", "dijit/_TemplatedMixin", "dijit/_OnDijitClickMixin", "dijit/_WidgetsInTemplateMixin", "dojox/grid/DataGrid", "dojo/store/Memory", "dojo/data/ObjectStore", "dijit/form/Button", "dijit/form/TextBox", "dijit/form/DateTextBox", "dojo/date/locale" ], function(declare, _WidgetBase, _TemplatedMixin, _OnDijitClickMixin, _WidgetsInTemplateMixin, template, DataGrid, Memory, ObjectStore) { return declare([_WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin, _OnDijitClickMixin], { templateString: "&lt;div class='${baseClass}'&gt;&lt;div id='the_grid' data-dojo-attach-point='theGrid'/&gt;&lt;/div&gt;", startup: function(){ var target = this.theGrid; dwrAjaxDao.all(function(result){ var dataStore = new ObjectStore({ objectStore:new Memory({ data: result }) }); var grid = new DataGrid({ store: dataStore, items:result, structure: [ {name:"ID", field:"id", width:"20%"}, {name:"Name", field:"name", width:"80%"} ] }, target); // using 'the_grid' also does not work grid.startup(); }); } }); } ); </code></pre> <p>I renamed and skipped parts of my code so it can be that I removed too much of the code.</p> <p>Problem is: when clicking on the menuItem 'second page', I don't see my datagrid. Although, it's present in the dom, but not visible. If it's done on the first page, which is visible at start up, it works.</p> <p>General questions: - is this the way to use dojo for this purpose? (using widgets to represent different pages) - Is there a way to create the widget when you select a child of the stackContainer? That way, I could first show the page, then make my datagrid.</p>

    1. COIs there any error in console / firebug? Also instead of using custom widget you can directly place datagrid in stackContainer.

    2. COno, no errors logged. I will switch to putting grid as widget in stackcontainer. Probably not a solution, but it's cleaner. If it solves something, I'll let you know. Thanks

    3. COStill not solved. If I give a dom-id of something that already exists, so that is not part of my template-body, than it works. when I create the grid from firebug after the whole page is rendered, with the div[id=thegrid] then it shows up too. Seems that I try to put the datagrid on the page too early, but I don't find the proper hook in _WidgetBase to put it in.

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).
