8.关于日期格式 o)h_H;
P@Hs`=
日期格式设定 "i
nd$Z`c
DataFormatString="{0:yyyy-MM-dd}" CNih6R
U_Vs.M.p
我觉得应该在itembound事件中 |t^E~HLm,
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) .k#U]M
O9G[j=U
9.获取错误信息并到指定页面 }u\])I3
VrHv)lUr
不要使用Response.Redirect,而应该使用Server.Transfer m}C>ti`VD
B;M?,<%FRU
e.g rA3$3GLQ-
// in global.asax vq0Vq(V=
protected void Application_Error(Object sender, EventArgs e) { q8FTi^=Kb
if (Server.GetLastError() is HttpUnhandledException) ? E1<!~
Server.Transfer("MyErrorPage.aspx"); 7S-ys+
MDnKX?Y
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) G/k2Pe{SL
} vleS2-]|
Nkjza:f{
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 6g2a[6G5
