8.关于日期格式 (V+iJ_1g{
+D+Rf,D
日期格式设定 :E9 @9>3S
DataFormatString="{0:yyyy-MM-dd}" k<NEauQ
baM@HpMhM
我觉得应该在itembound事件中 /3v`2=b
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) L[:b\O/p,
j%s:d(H`
9.获取错误信息并到指定页面 Kkds^v6
6oLq2Z8uP
不要使用Response.Redirect,而应该使用Server.Transfer y{\K:
?qjlWCV|e
e.g !+I!J
s"
// in global.asax q]o^Y
protected void Application_Error(Object sender, EventArgs e) { |b:91l
if (Server.GetLastError() is HttpUnhandledException) , 8F(R%v
Server.Transfer("MyErrorPage.aspx"); ZzuWN&
z@em1W0?Z
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) d_}q.%*
} >NN&j#;x~
Tj*Vk $}0
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 t1tZ:4
