string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() BWz7m9T

8.关于日期格式 , C88%k
3,8>\yf`
日期格式设定 5MH\Gqe7
DataFormatString="{0:yyyy-MM-dd}" ^+zF;Q'
_2V L%
我觉得应该在itembound事件中 3_W1)vd{
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) %aU4d
e^

9.获取错误信息并到指定页面 x8Rmap@L.
3T$gT
不要使用Response.Redirect,而应该使用Server.Transfer i0ax`37
p4;A[2Ot`:
e.g he0KzwBF
// in global.asax +B$o8V
protected void Application_Error(Object sender, EventArgs e) { CPVR
if (Server.GetLastError() is HttpUnhandledException) 48CLnyYiF
Server.Transfer("MyErrorPage.aspx"); H/>86GG
;E/:_DWPD
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) k=j--`$8k
} <@9p|[!
=PiDZS^"
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 HTK79
