+/**
+ * @class Ext.DataView
+ * @extends Ext.BoxComponent
+ * A mechanism for displaying data using custom layout templates and formatting. DataView uses an {@link Ext.XTemplate}
+ * as its internal templating mechanism, and is bound to an {@link Ext.data.Store}
+ * so that as the data in the store changes the view is automatically updated to reflect the changes. The view also
+ * provides built-in behavior for many common events that can occur for its contained items including click, doubleclick,
+ * mouseover, mouseout, etc. as well as a built-in selection model. <b>In order to use these features, an {@link #itemSelector}
+ * config must be provided for the DataView to determine what nodes it will be working with.</b>
+ *
+ * <p>The example below binds a DataView to a {@link Ext.data.Store} and renders it into an {@link Ext.Panel}.</p>
+ * <pre><code>
+var store = new Ext.data.JsonStore({
+ url: 'get-images.php',
+ root: 'images',
+ fields: [
+ 'name', 'url',
+ {name:'size', type: 'float'},
+ {name:'lastmod', type:'date', dateFormat:'timestamp'}
+ ]
+});
+store.load();
+
+var tpl = new Ext.XTemplate(
+ '<tpl for=".">',
+ '<div class="thumb-wrap" id="{name}">',
+ '<div class="thumb"><img src="{url}" title="{name}"></div>',
+ '<span class="x-editable">{shortName}</span></div>',
+ '</tpl>',

+);
