8.关于日期格式 GqMB^Ad
L^x5&CCwk
日期格式设定 FXxN>\76.
DataFormatString="{0:yyyy-MM-dd}" UtPwWB_YV
L,
#Byao
我觉得应该在itembound事件中 S<9gyW
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ;xI0\a7
_^-D _y
9.获取错误信息并到指定页面 df yrn%^Ia
#XfT1
不要使用Response.Redirect,而应该使用Server.Transfer Yq{jEatY{/
CMFC"e Se
e.g
<irpmRQr
// in global.asax _trpXkQp
protected void Application_Error(Object sender, EventArgs e) { "H@Fe
if (Server.GetLastError() is HttpUnhandledException) Eny!R@u7q
Server.Transfer("MyErrorPage.aspx"); z:?:
{H'X)n$
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 5DUi4 Cbgy
} qNy-o\;XN
`}Eh[EOHJ
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 lj
