Y{y #us1
日期格式设定 ^EU&6M2
DataFormatString="{0:yyyy-MM-dd}" 'R6D+Vk/

我觉得应该在itembound事件中 }i_[wq{E&
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) lv9Ss-c4

9.获取错误信息并到指定页面 E&0A W{
:4$Ex2
不要使用Response.Redirect,而应该使用Server.Transfer p}uTqI
J)(H-xvV
e.g &rj6<b1A
// in global.asax Ne/jvWWN
protected void Application_Error(Object sender, EventArgs e) { /:dVW"A|
if (Server.GetLastError() is HttpUnhandledException) Y.rHl4
Server.Transfer("MyErrorPage.aspx"); (\FjbY9&
}|f\'S
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) (_]{[dFr%
} 9Vk61x6
R7T"fN
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 %kD WUJZ
