Extjs导入Excel文件之后grid自动刷新显示刚插入的数据

var winUpload = new Ext.Window({
            title: '导入excel文件',
             400,
            height:200,
            listeners: {
                close: function () {
                    store.load();
                    grid.getView().refresh();
                }
            },
            minWidth: 300,
            closeAction:'hide' ,
            minHeight: 100,
            layout: 'fit',
            plain:true,
            bodyStyle:'padding:5px;',
            buttonAlign:'center',
            items: formUpload,
        });

Ext创建window窗体，添加监听listeners，当窗体关闭时执行store.load();grid.getView().refresh(); 加载数据源，刷新grid表格。
