    <p>I am having trouble filtering an array store.</p> <p><strong>Situation</strong></p> <p>I have 2 comboboxes with an array store. combobox 1 and combobox 2, both are in mode 'local' and have a predefined array store. when i click and select a row in the first combobox, I apply a filter on the second combobox (which was not yet cliked upon). The thing is that the second combobox did not render it's data (or html) yet so the filter wasn't applied. </p> <p>when i click on the second combobox, and then clicking on the first, the filter is applied and working.</p> <p>my question is, how to pre-render an array_store/combobox?</p> <p>I did try to expand the combobox first, but also didn't work for me. (see commented code)</p> <pre><code>var store1 = new Ext.data.ArrayStore({ fields: ['id','name'], data:somedata //array of some data }); var store2 = new Ext.data.ArrayStore({ fields: ['id','name'], data:somedata //array of some data }); var combobox1 = { name: 'combobox_1', xtype: 'combo', hiddenName: 'combobox_1', store: store1, displayField:'name', valueField:'id', mode:'local', triggerAction: 'all', allowBlank:true, emptyText:'Select...', listeners:{ select: function(st, r){ var selected = r.get('name'); var combobox2 = Ext.getCmp('combobox2'); //combobox2.expand(); combobox2.store.filter([ { property : 'name', value : selected, anyMatch : true, caseSensitive: false } ]); }, scope:this } } var combobox2 = { name: 'combobox_2', xtype: 'combo', hiddenName: 'combobox_2', store: store2, id: 'combobox2' displayField:'name', valueField:'id', mode:'local', triggerAction: 'all', allowBlank:true, emptyText:'Select...', } </code></pre>

    3. CONo. You don't have to render drop down list to filter the store. You just bind the store to the combobox and filter it. If the combobox is rendered itself by then everything should be fine.

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.
