8opd0'SNaB
日期格式设定 @TQzF-%#7
DataFormatString="{0:yyyy-MM-dd}" o]@Mg5(8Q

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) r6b;v2!8

9.获取错误信息并到指定页面 {^T_m)|n
j; MQ_?"iN
不要使用Response.Redirect,而应该使用Server.Transfer L0Ycf|[s,
+W%3VV$
e.g *el~sor;S
// in global.asax {!L25
protected void Application_Error(Object sender, EventArgs e) { N^TE
;BM
if (Server.GetLastError() is HttpUnhandledException) @Y&UP
Server.Transfer("MyErrorPage.aspx"); XkEJ_;:
joRrsxFU
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) +%~/~1
} q:/3uC7
pBxyq"z
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 W5^<4Ya!
