我用的吴旗娃的分页控件AspNetPager，我能够实现在初始化页面的时候能显示显示总的记录数、共多少页、当前是第几页，而且还能分页。但是在按照查询功能的时候AspNetPager不能够按照查询出的结果显示总的记录数、共多少页、当前是第几页，而还是第一次初始化的页面。
举个例子：我的表中一共有30条记录。在页面初始化时DataGrid显示30条记录 当显示第1/3页（其中DataGrid每页显示10条记录）.按照名称查询出应该是15条记录，那么AspNetPager就应该显示15条记录 当显示第1/2页.
不知道我说清楚了没有，怎么实现。谢谢啦。

可以参考一下
重新获取符合条件的记录总数绑定到aspnetpager的RecordCount属性
然后把文本框的条件放到viewstate里面
绑定gridview多加一个判断就行了
if(viewstste["title"]==null)
{
模糊查询
}
else
{
正常查询
}
不明白的话加我QQ393559600
