    <p>I have a little problem here with Sencha Touch 2:</p> <p>My App has 2 views/lists: news and events. Both have detail views. On the news list Iam showing an filter and sort button and on the events list Iam want to show only the filter button.</p> <p>When I click on an item, the nav controller automatically adds an back button.</p> <p>What I do atm is: - when the user clicks an item in the list: hide all buttons - when the user clicks the back button: show all buttons</p> <p>And thats the problem... I cannot see if it was the back button on the news detail view or the events detail view.</p> <p>In my controller I have:</p> <pre><code>"mainnav[id=mainNav]": { back: 'showButtons', }, </code></pre> <p>when I try:</p> <pre><code>"panel[id=newsDetail]": { back: 'showButtons', }, </code></pre> <p>the event gets not triggered. So how can I know is it was the news or events back button?</p> <p>Thanks!</p> <p>Edit: Its not easy to explain... here is some more information: The "mainNav" is a navigation view and the back button gets added to its toolbar.</p> <pre><code>Ext.define('MyApp.view.MainNav', { extend: 'Ext.navigation.View', alias: 'widget.mainnav', config: { id: 'mainNav', maxWidth: '350px', items: [ { xtype: 'tabpanel', layout : { type : 'card' }, ... items: [ { xtype: 'list', title: 'News', id: 'newsList', store: 'newsStore', grouped: true, onItemDisclosure: true, ... { xtype: 'list', title: 'Events', iconCls: 'team', id: 'eventList', store: 'eventStore', onItemDisclosure: true, ... tabBar: { docked: 'bottom' } ... and the navigation bar with its buttons: navigationBar: { minWidth: '', width: '', id: 'navBar', layout: { align: 'center', type: 'hbox' }, items: [ { xtype: 'button', id: 'settingsButton', align: 'left', iconCls: 'settings6', iconMask: true }, { xtype: 'button', id: 'filterbutton', align: 'right', iconCls: 'list', iconMask: true } ] }, </code></pre> <p>What iam trying to do now:</p> <pre><code>"mainnav[id=mainNav]": { back: 'showButtons', }, </code></pre> <p>get triggered when the user hits the back button (doesnt matter if he id in newsDetail or eventsDetail) but I want to know which view the user sees after he taps the back button.</p> <p>If he sees the news list then I want to show both buttons (filter and seetings) but is he sees the events list I only want to show one button. I need something like:</p> <pre><code>showButtons: function(component, options) { if(Ext.getCmp(backButton).down().getId() == 'newsList'){ //show 2 buttons }else{ //show one button } } </code></pre> <p>Sorry if the answer is confusing... I dont know how I could explain it better. Anyway, I would appreciate any help/idea!</p>

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.
