VS中的DataPager分页

微软的DataPager分页功能很强大，不要设置数据库存储过程，只要添加个DataPager控件，关联下要分页的控件，简单设置就可以有不错的分页效果。当然要有更理想的效果还是要前台和后台处理下。

winform下的DataPager 显示模式:

webForm下的样式由TemplatePagerField，NextPReviousPagerField和NumericPagerField控制

通过设置上面几个控件的配合也可以达到winForm下的效果，这3个控件中最重要的是TemplatePagerField控件。

下面简单看看TemplatePagerField控件可以怎么设置：
