gridview自定义分页 aspNetPager用法

这几天做gridview分页，自带的分页不好用。从网上搜刚开始搜了一个aspNetPager.dll，替换原来的一个dll，自己设置了一些，比如这个控件不显示中文，后来我改成中文的“上一页”、“下一页”、“首页”“尾页”，把ShowPageIndexBox设置为默认true，这样当前页也显示了，还能跳转。

还设置了 显示自定义区域，默认是不显示了，我改成left，然后再设置下自定义的html，结果就可以显示了，我显示的是 一共有多少行。

作为这个可有成就感了，虽然只是在别人的基础上修改了下。

今天我又想实现自定义每页多少行，在网上搜了搜，网上说7.1以上版本才能用，我又下载个7.2版本，真是感谢大家。我按照百度文库中一篇文章说的设置了下，这个文章说的properties.cs文件其实不存在，对应的AspNetPager.cs文件，一步步设置，还添加了一个.xml文件，设置值为true，又改了ShowPageSizeBox，让它永远返回true，哇塞，大功告成。

下载dll文件，使用反编译工具解码后，双击工程文件，改AspNetPager.cs就可以了，然后重新生成。

最后在意感谢大家分享资源。

附上我改后的代码。
