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. 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. - * - *

The example below binds a DataView to a {@link Ext.data.Store} and renders it into an {@link Ext.Panel}.
