8.关于日期格式 @sZ7Ka
X@tA+
日期格式设定 I(7iD. ^:
DataFormatString="{0:yyyy-MM-dd}" RHNAHw9
s[h;9
I1w
我觉得应该在itembound事件中 ftPhE)i
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ^lZ7% 6
pKj:)6t"
9.获取错误信息并到指定页面 ip}%Y6Wj
h?OSmzRLd
不要使用Response.Redirect,而应该使用Server.Transfer biS[GyQ
/<$|tp\Rc
e.g _RxnB?
// in global.asax fS|e{!iI"
protected void Application_Error(Object sender, EventArgs e) { dJnKa]X
if (Server.GetLastError() is HttpUnhandledException) ~aQR_S
Server.Transfer("MyErrorPage.aspx"); C6a-
85[
7lO)[
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ~Y*.cGA
} Ank_;jo
dz/fSA
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 Cu24xP`
