8.关于日期格式
[g/g(RL
H<q:+
日期格式设定 ,JjTzO
DataFormatString="{0:yyyy-MM-dd}" J0x)m2
Lh0<A%

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))

9.获取错误信息并到指定页面 <vAg\Tv:S
p'R}z|d)
不要使用Response.Redirect,而应该使用Server.Transfer 6Y=$7%z
r+U-l#Q
e.g KUp
lN1Sy
// in global.asax K4
>d
protected void Application_Error(Object sender, EventArgs e) { ?2i``-|Wa
if (Server.GetLastError() is HttpUnhandledException) 6dNo!$C^
Server.Transfer("MyErrorPage.aspx"); ;+5eE`]a/L
7[K$os5al
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) %8v?dB;>x`
} ,,6e }o6
/1^%32c
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 dtnAMa5$T
