Paging is used to reduce the amount of data exchanged with the client. * Note: if there are more records/rows than can be viewed in the available screen area, vertical * scrollbars will be added.</p> * <p>Paging is typically handled on the server side (see exception below). The client sends * parameters to the server side, which the server needs to interpret and then respond with the * approprate data.</p> * <p><b>Ext.PagingToolbar</b> is a specialized toolbar that is bound to a {@link Ext.data.Store} * and provides automatic paging control.
