8.关于日期格式 '`}D+IQ(j
W!el[@
日期格式设定 G:+D1J]
DataFormatString="{0:yyyy-MM-dd}" _@\-`>J
S9:ij1
我觉得应该在itembound事件中 y46sL~HRv
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) IH*G7;

9.获取错误信息并到指定页面 {>9<H]cSP
w,6gnO
不要使用Response.Redirect,而应该使用Server.Transfer g NE"z
uUaDesz~=
e.g a$uDoi
// in global.asax G@rh/b<$
protected void Application_Error(Object sender, EventArgs e) { [D|Uwq
if (Server.GetLastError() is HttpUnhandledException) M&Q&be84
Server.Transfer("MyErrorPage.aspx"); uAYDX<Ja9
0Q>
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) .gNJY7`b

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 Yc[vH=gV}
