q_86nvB<
日期格式设定 5gKXe4}\/|
DataFormatString="{0:yyyy-MM-dd}" <[A;i

我觉得应该在itembound事件中 Ti>2N
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ~9Cw5rwH<;

9.获取错误信息并到指定页面 -Ic<.ix
-GZ:}<W6+
不要使用Response.Redirect,而应该使用Server.Transfer 4|h>.^
8SOfX^;o
e.g Wxzh'c#\8
// in global.asax =;{8)m
protected void Application_Error(Object sender, EventArgs e) { D!rD-e
if (Server.GetLastError() is HttpUnhandledException) ge|Cvv
Server.Transfer("MyErrorPage.aspx"); rYO~/N
vRMGNz_P7[
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Nn{/_QG
} )^7- qy
_#y=T20'3
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 m2v'zJd}g
