重写的GridView，支持CheckBox选择，DataTable和List排序,SQL分页等

重新封装了一个 GridView，支持如下功能：

1. CheckBox选择记录，指定CheckBox的位置
2. 支持List，DataSet,Datatable 排序
3. 排序时在Header部分出现图标
4. 封装了PageIndexChanged 和DataBind，不用每页都写。
5. 支持SQL分页和ApsNetPager等分页控件。

注： 没有加入很多的功能，因为本身需要的就是一个轻量级的GridView，产生近可能少的代码。

另：选择高亮功能是用JQuery实现的，因此使用时需要JQuery的运行库。

代码1 ： 辅助对象，实现Sort排序。（其实这部分功能可以用LINQ来做，会简单很多，当这个类已经用了很久了，懒得改了）

重新封装了一个 GridView，支持如下功能：

1. CheckBox选择记录，指定CheckBox的位置
2. 支持List，DataSet,Datatable 排序
3. 排序时在Header部分出现图标
4. 封装了PageIndexChanged 和DataBind，不用每页都写。
