8.关于日期格式 E9}{1A
8VQ 24r
日期格式设定 yx>_scv,T
DataFormatString="{0:yyyy-MM-dd}" ycAKK?O*
jS<_ )
我觉得应该在itembound事件中 tPfFqqT
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ]zfG~^.

9.获取错误信息并到指定页面 Vj?DA5W`'
+&|S'7&{
不要使用Response.Redirect,而应该使用Server.Transfer Sr_VL:Gg
dy>!KO
e.g -JT/9IQ
// in global.asax 'h1b1,b~
protected void Application_Error(Object sender, EventArgs e) { Uf\nFB? ^
if (Server.GetLastError() is HttpUnhandledException) XfYC7-e9c
Server.Transfer("MyErrorPage.aspx"); j&R+2%
W# US#<9Y
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Te,$M3|
} b)#Oc,
;GGK`V
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 ^U[D4UM
