8.关于日期格式 -+#QZ7b
.{pc5eUf
日期格式设定 I2U/\
DataFormatString="{0:yyyy-MM-dd}" ^#^\@jLm
rD7L==Ld
我觉得应该在itembound事件中 ]z^*1^u^ig
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) _{d0Nm

9.获取错误信息并到指定页面 x*p>l !
q4'Vb
不要使用Response.Redirect,而应该使用Server.Transfer ,5tW|=0@
Q
db~I#}m'
e.g y@\R$`0J
// in global.asax zcn> 4E)
protected void Application_Error(Object sender, EventArgs e) { #n9:8BKf
if (Server.GetLastError() is HttpUnhandledException) .BaU}-5
Server.Transfer("MyErrorPage.aspx"); W,\LdQ
QX1rnVzg0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) dI[hQxU
} %Ls5:Z=
L?WF[nFR
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 L)0j&
