1、devexpress.xtraeditors.datanavigator刚拖到winform窗体上的样子：
设置datanavigator控件属性dock=bottom;textlocation=end;textstringformat=第 {0}页 ,共 {1}页;
如果想显示tooltip，需把showtooltips设置为true.设置button的hint为自己想要显示的内容即可。
比如：
在运行时会有下面效果：
上图中的首页、前一页、后一页、尾页的图片是自定义的，那么怎么使用自定义图片呢？
拖拽一个imagelist控件，然后在imagelist中选择要使用的自定义图片
然后在buttons选项卡下将imagelist设置为刚才选择过图片的imagelist1控件，然后在datanavigator控件
buttons下选择荼盘即可，比如下图的first
按钮事件处理：
