string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() yKi* 8N"e<

Em6P6D>S>,
日期格式设定 X~+AaI:~K
DataFormatString="{0:yyyy-MM-dd}" bzj9U>eY
8d4:8}
我觉得应该在itembound事件中 f[r?J/;P9
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Qk`ykTS!

9.获取错误信息并到指定页面 ;&iZ{
xbUL./uj
不要使用Response.Redirect,而应该使用Server.Transfer -O&u;kh4g
U-h'a:
K
e.g Q5K<ECoPk
// in global.asax VKGH+j[
protected void Application_Error(Object sender, EventArgs e) { oY
NIJXln
if (Server.GetLastError() is HttpUnhandledException) MawWgd*
Server.Transfer("MyErrorPage.aspx"); SK][UxoHm
WF#3'"I
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) dio<?6ZD9P
} $nf5bo/;
1UHlA8w7Q
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 S2APqRg*

10.清空Cookie owR`Z`^h)
Cookie.Expires=[DateTime]; .@5RoD[o
