            id:'editToolBar',
            items: [
                    {
                        xtype: 'tbbutton',
                        text: "Zoom",
                        handler: function() {

attribGridPanel.getSelectionModel().each(function(rec) {
                                var feature = rec.get("feature");

mapPanel.map.zoomToExtent(feature.geometry.getBounds());
                                })
                                    }
                        }
                ]
