K1[(%<Gp
日期格式设定 k#pNk7;MZ
DataFormatString="{0:yyyy-MM-dd}" t6a$ZN;

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) mZ}C)&,m2

9.获取错误信息并到指定页面 lko

不要使用Response.Redirect,而应该使用Server.Transfer rhA>;9\
@86?!0bt
e.g { K*
// in global.asax ;}E$>]*Yn
protected void Application_Error(Object sender, EventArgs e) { YB3?Ftgw
if (Server.GetLastError() is HttpUnhandledException) RLr^6+v)U
Server.Transfer("MyErrorPage.aspx"); a5@XD_b
56T{ JTo
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) [3fmhc
} 5;Q9Z1

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 ]gG&X3jaKq
