8.关于日期格式 nLBi}T
!9EbG
日期格式设定 PpR
eqmo
DataFormatString="{0:yyyy-MM-dd}" );fPir?+
Hu$JCB-%
我觉得应该在itembound事件中 RH&}'4JE:
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) BmCBC,j<v>
qim|=
9.获取错误信息并到指定页面 5S&^mj-9
uN(N2m
不要使用Response.Redirect,而应该使用Server.Transfer k:CSH{ s5{
*|)O
e.g 'd9cCQ}
// in global.asax FO?I}G22
protected void Application_Error(Object sender, EventArgs e) { <u2iXH5w
if (Server.GetLastError() is HttpUnhandledException) "Kf4v|6;
Server.Transfer("MyErrorPage.aspx"); Q&?B^[N*Q
GlaZZ,
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #oEq)Vq>g|
} (eO_]<wmky
q4ej7T8
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 @{x+ln1r

10.清空Cookie gEnc;qb

Response.Cookies("UserName").Expires = 0 a,\GOy(q{
