8.关于日期格式 t: ,lz8Y~
EiDpy#f}
日期格式设定 4(Y-TFaf
DataFormatString="{0:yyyy-MM-dd}" [iyhrc:@
:9q|<[Y^
我觉得应该在itembound事件中 '~z`kah
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) P8w56

9.获取错误信息并到指定页面 .#K\u![@N
RaymSh
不要使用Response.Redirect,而应该使用Server.Transfer ymR AQVv
s%m?Yh3
e.g =NPo<^Lae
// in global.asax /nt%VLms%
protected void Application_Error(Object sender, EventArgs e) { nn">
if (Server.GetLastError() is HttpUnhandledException) \9sJ`,T?
Server.Transfer("MyErrorPage.aspx"); a",
8N"'
YW8Odm
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Tv%
Z|%*
} uhwCC
?fpI,WFu
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 +<f+kh2L
