+</span> * @class Ext.view.View
+ * @extends Ext.view.AbstractView
+ *
+ * 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>
+ *
+ * The example below binds a DataView to a {@link Ext.data.Store} and renders it into an {@link Ext.panel.Panel}.
+ *
+ * {@img Ext.DataView/Ext.DataView.png Ext.DataView component}
