日期格式设定 }PD?x4

我觉得应该在itembound事件中 LNtBYdB`pK
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) iCnKQG

9.获取错误信息并到指定页面 p1q"[)WVn^
Bi9 S1p
不要使用Response.Redirect,而应该使用Server.Transfer ,..&j+m
a?_N8|k[
e.g }O-|b#Q
// in global.asax `J#(ffo-
protected void Application_Error(Object sender, EventArgs e) { DR;rK[f
if (Server.GetLastError() is HttpUnhandledException) NZ7g}+GTG
Server.Transfer("MyErrorPage.aspx"); m\RU|Z
s7[du_)
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) GG-7YJ
} Ru`&>E
>:WnCkbp
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 ycTX\.KV
