接收参数: >B!E 6ah
string a = Request.QueryString("id"); ,.A@U*j
string b = Request.QueryString("id1"); >-*rtiE

8.关于日期格式 <a&w$Zc/
@;G%7&ps
日期格式设定 q`VkA
\
DataFormatString="{0:yyyy-MM-dd}" {%_D>y
:qc?FQ
;
我觉得应该在itembound事件中 j[Jwa*GQP
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) +B[XTn,Cru
:q >)c]
9.获取错误信息并到指定页面 }uwZS=pw
2g~W})e
不要使用Response.Redirect,而应该使用Server.Transfer f?r{Q
TNDp{!<|L;
e.g :-_"[:t 5Z
// in global.asax l)e6*sDZ,
protected void Application_Error(Object sender, EventArgs e) { $O&N
if (Server.GetLastError() is HttpUnhandledException) :IX,mDO
Server.Transfer("MyErrorPage.aspx"); T/0cPn0>
riF-9
%i
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) j u&v4]
} d}aMdIF!e
{Hie%2V
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 ZA&bp{}D
