8.关于日期格式 Boj R"
m{oe|UVcmr
日期格式设定 z/#,L!Z3
DataFormatString="{0:yyyy-MM-dd}" iKq_s5|sW
.QY>@b\
我觉得应该在itembound事件中 A":=-$)
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) OcB&6!1u

9.获取错误信息并到指定页面 tk0m[HN@eV
2fdN@iruB
不要使用Response.Redirect,而应该使用Server.Transfer y/@Bhzc
PE.UNo>o
e.g :E{)yT
// in global.asax .BjWZj
protected void Application_Error(Object sender, EventArgs e) { 7!qeIz
if (Server.GetLastError() is HttpUnhandledException) |keU+De
Server.Transfer("MyErrorPage.aspx"); :@p]~{m :G
aP (~l_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) [`|t( E'
} JQLQS
qo:Zc`t(R
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 iwIn3R,
