SqlPager的再次改进(带数字翻页以及翻页样式设置功能)

         使用MSDNSqlPager这么久以来，对SqlPager已经有了比较深入的了解了，总的说来，SqlPager是一个不错的分页控件。对于一般的需求已经能够很好的满足，而且性能比较好；但是美中不足的地方是：它只能对不重复的列进行排序，一旦你用于排序的列的数据有重复现象那么就将出现漏掉数据的情况；对于这个情况我目前也没有好的解决方法，唯一的办法就是先在查询中进行排序，然后再生成该查询结果的自动编号列，不过这个功能在SqlServer2000下不好做，在SQL2005中到自带该功能！闲话就到此，下面转入正题！
         以前也对SqlPager进行过一些小的修改，不过还是感觉功能上欠缺了一些！由于一个小项目的需要以及我对SqlPager分页的热爱，所以我又对其进行了修改！主要新增功能如下：1.带类似于百度那种数字翻页功能  2.可以为翻页的数字设置样式表中的样式。
如图所示：
