aspx页面的怪问题

我做了一个AddIntegration.aspx页面,为何点击"增加记录"数据写到了数据库里了,但是页面变成空白,这是什么原因.
看不到任何东西,在空白地方点击右键,查看源文件.结果如下
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=gb2312"></HEAD>
<BODY></BODY></HTML>怎么解决

是不是使用了 Response.End()?
使用 Response.End()
由于代码太多,所以没有贴出来
下面我把部门贴出来
请大家看看
