string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() "z*:'8;E

8.关于日期格式 ~DLIz g7p!
oj}"H>tTp
日期格式设定 _eLVBG35z
DataFormatString="{0:yyyy-MM-dd}" HBLWOQab
zzvlI66e
我觉得应该在itembound事件中 AV @\ +0
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) %B EC]

9.获取错误信息并到指定页面 ][Y^-Ak1
7SI)1_%G
不要使用Response.Redirect,而应该使用Server.Transfer ke/_k/
ew#T8F[
e.g GoE#Mxh xo
// in global.asax >kdM:MK
protected void Application_Error(Object sender, EventArgs e) { OR+A_:c.D
if (Server.GetLastError() is HttpUnhandledException) oTOfK}
Server.Transfer("MyErrorPage.aspx"); bdV3v`
t ,qul4y}
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
"7?js $
} }sMW3'V
{U
<tc4^
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 Q:S\0cI0

10.清空Cookie 8.I9}_
