D
ah(k!0PV
日期格式设定 ($8!r|g5#
DataFormatString="{0:yyyy-MM-dd}" U'~]^F%eyu

我觉得应该在itembound事件中 +D[C.is>]}
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Mhb~wDQl

9.获取错误信息并到指定页面 tO D}&

不要使用Response.Redirect,而应该使用Server.Transfer L)S

g706*o)h
e.g glkH??S
// in global.asax 1=z\,~b
protected void Application_Error(Object sender, EventArgs e) { r^ '
if (Server.GetLastError() is HttpUnhandledException) Fiw^twz5
Server.Transfer("MyErrorPage.aspx"); 5d# 73)x$
U'Y,T$Q
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 79k+R9m
} (h[.

y@AUSh;
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 W@%g_V}C*
