z( wXs&z;
日期格式设定 {/ta1&xyG
DataFormatString="{0:yyyy-MM-dd}" '' 6

我觉得应该在itembound事件中 F~1R.r_Lu
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) yWzTHW`)Mr

9.获取错误信息并到指定页面 *D,T}N
E'Bt1u
不要使用Response.Redirect,而应该使用Server.Transfer .
fIodk
a;K:~R+@,
e.g isjkfl-!
// in global.asax o&]qjFo\m
protected void Application_Error(Object sender, EventArgs e) { k;sUD mrO
if (Server.GetLastError() is HttpUnhandledException) S~T[*Z/m
Server.Transfer("MyErrorPage.aspx"); X6)LpMm
yFSL7`p+
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ^|Y!NHYH$Z
} -LyIu#
z?PF9QL1
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 B !XT:.+
