string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() =r`>tWs

8.关于日期格式 nOTe 3?i>
T$!Pkdh
日期格式设定 L+K,Y:D!W
DataFormatString="{0:yyyy-MM-dd}" yi.GD~69
L5DeLF+
我觉得应该在itembound事件中 (! a;}V<7
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) tXfXuHa

9.获取错误信息并到指定页面 kltorlH
/`s{!t#Y
不要使用Response.Redirect,而应该使用Server.Transfer ,,8'29yEq
Mh"iyDGA
e.g
{c}n."`
// in global.asax br;~}GR_h
protected void Application_Error(Object sender, EventArgs e) { |Ml~_m
if (Server.GetLastError() is HttpUnhandledException) #b,!N
Server.Transfer("MyErrorPage.aspx"); l3N '@GO
j4%\'xj:
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Uc<BLu;
} y/Ui6D
,8[R0wsBaz
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 B,b^_4XX$
