gridview不能及时刷新

Question

就是  在添加之后不能即时的显示刚添加的数据 ，删除也是，必须要重新生成下项目之后才能看，下面是代码，请各位大大帮忙看看，是不是哪里出错了， protected void Page_Load(object sender, EventArgs e)

Answer 1

设断点试一下在你执行完你要的操作之后，重新databind()了吗？

Answer 2

我们这样很难看出问题的，
你把GetList(5, this.AspNetPager1.CurrentPageIndex, strWhere, "id", "id,title,typeid");
和Add函数贴出来
还有重复的哪行是你添加的哪行吗？？

Answer 3

一语惊醒梦中人啊，我的bll里，加了个缓存，大爷的，我给忘记了
谢两位捧场，分给两位平分了哈
