8.关于日期格式 <B8!.|19
Q^txVUL
日期格式设定 001FmiV
DataFormatString="{0:yyyy-MM-dd}" 5(HG|
x{/g(r={}
我觉得应该在itembound事件中 5iydZ
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))
zi`o#+
SQt4v"
9.获取错误信息并到指定页面 -5QZJF2~
A
'];`
不要使用Response.Redirect,而应该使用Server.Transfer !H>R%g#28_
M?uC%x+S$_
e.g [-oc>;`=l
// in global.asax AX/m25x
protected void Application_Error(Object sender, EventArgs e) { w!clI8v/
if (Server.GetLastError() is HttpUnhandledException) H\tUpan6fy
Server.Transfer("MyErrorPage.aspx"); PdtvU-(
\7'{g@C(
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ?"g2v-jTK
} &m:uO^-D
/{--+
C
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 =^ 50FI|
