  8 * @class Ext.DataView
  9 * @extends Ext.BoxComponent
 10 * A mechanism for displaying data using custom layout templates and formatting. DataView uses an {@link Ext.XTemplate}
 11 * as its internal templating mechanism, and is bound to an {@link Ext.data.Store}
 12 * so that as the data in the store changes the view is automatically updated to reflect the changes.  The view also
 13 * provides built-in behavior for many common events that can occur for its contained items including click, doubleclick,
 14 * mouseover, mouseout, etc. as well as a built-in selection model. <b>In order to use these features, an {@link #itemSelector}
 15 * config must be provided for the DataView to determine what nodes it will be working with.</b>
 16 *
 17 * <p>The example below binds a DataView to a {@link Ext.data.Store} and renders it into an {@link Ext.Panel}.</p>
 18 * <pre><code>

 26    ]
 27});
 28store.load();
