问题描述:EnableEventValidation="true"
Event validation is a feature designed to help prevent injection attacks (of course it can't prevent attacks all by itself).
如果我们往服务器端生成的代码加入了客户端生成的数据,如果参考页面中提出的,下拉菜单的问题。
这样会提示出错信息

我是在做GridView的分页时,出现的问题。我把代码贴出来,大家看看。
这是.SKIN文件下的设置
这是加到GridView后面的分页代码
解决方案:
在.CS页面中加了一个事件注册处理:
protected override void Render(HtmlTextWriter writer)
{
ClientScript.RegisterForEventValidation(gvDB.UniqueID, "Page$First");
base.Render(writer);
}
关于分页的做法,网上有很多做法。
我的任务是在原来的基础上加上分页的功能,这次改动不算太多。
欢迎大家讨论。
