4&%0%
日期格式设定 C{(&Yy"
DataFormatString="{0:yyyy-MM-dd}" n@|5PI"bx

我觉得应该在itembound事件中 D$@5$./
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) qF'lh

9.获取错误信息并到指定页面 c\A

不要使用Response.Redirect,而应该使用Server.Transfer +~xY}
'u@,,FFz[K
e.g K#Ia19au5
// in global.asax yp}J+/PX}
protected void Application_Error(Object sender, EventArgs e) { Buc{dcL/
if (Server.GetLastError() is HttpUnhandledException) NULew]:5
Server.Transfer("MyErrorPage.aspx"); U'~M(9uv:
J5dwd,FQ
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) NxY B)`~
} %8Eu{3
r@")MOGc
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 (;\"
