DetailsView的wasn't handled问题
郁闷,baidu不到,只好来问了.
错误提示是The   DetailsView   'DetailsView1 '   fired   event   ModeChanging   which   wasn 't   handled

首先,第一次进入页面没问题,能显示DetailsView   ,但是我一点击Edit   User   Info就出错.
我DetailsView   没有DataSourceID,直接绑到了一个ArrayList上,难道这就是出错的原因??难道是OnItemUpdating事件有错??首先名字什么的绝对是匹配,然后OnItemUpdating事件里的代码我是直接抄的,原代码都没有问题,怎么抄过来就有问题了?只不过原代码DetailsView   是有DataSourceID   而已.

下面这个是DetailsView   的代码
<asp:DetailsView   AutoGenerateRows= "False "   ID= "DetailsView1 "   runat= "server "   OnItemUpdating= "DetailsView1_ItemUpdating1 "   >
