P~>nlm82]
日期格式设定 wO
NQlt
DataFormatString="{0:yyyy-MM-dd}" l]cQ7g5

我觉得应该在itembound事件中 ga%77t|jm3
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Q"uu&JC

9.获取错误信息并到指定页面 izA3 INT
ZH:X4!
不要使用Response.Redirect,而应该使用Server.Transfer UQr+\ u
I!~Omr@P
e.g roQIP%h!
// in global.asax a)b@en;v
protected void Application_Error(Object sender, EventArgs e) { <{j9|mt
if (Server.GetLastError() is HttpUnhandledException) L1K_|X
Server.Transfer("MyErrorPage.aspx"); > xw+2<
]B[Qdn
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /2I("x]
} EQ-~e
7G2N&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 ZrBxEf$f
