8.关于日期格式 ywp_,j9F
fSbLkd 9
日期格式设定 j:cu;6|
DataFormatString="{0:yyyy-MM-dd}" E9\"@wu[d

我觉得应该在itembound事件中 neu+h6#H
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) vy~6]hH

9.获取错误信息并到指定页面 "J,|),Yd
8)8~c@
不要使用Response.Redirect,而应该使用Server.Transfer y0p=E^QM
M@es8\&S.
e.g X >7Pqn'
// in global.asax N-2#-poDe
protected void Application_Error(Object sender, EventArgs e) { {oY"CZ2
if (Server.GetLastError() is HttpUnhandledException) >Y4^<!\v
Server.Transfer("MyErrorPage.aspx"); YA@?L!F
PJZ;wqTD_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) l\
dPfJ
} }K 'A/]'
oA5Qk3b:
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 5b rM..
