K)oN^
日期格式设定
BgG+
DataFormatString="{0:yyyy-MM-dd}" 6? (8KsaN
m+'X8}GC#O
我觉得应该在itembound事件中 9;c]_zt
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Z Q9's
#`Et{6WS
9.获取错误信息并到指定页面 "_&HM4%!
=>h~<88#5
不要使用Response.Redirect,而应该使用Server.Transfer I."4u~[
v3jx2Z
e.g y+[wlo&WC
// in global.asax (au7wI{
protected void Application_Error(Object sender, EventArgs e) { b+}*@xhl
if (Server.GetLastError() is HttpUnhandledException) q}R"
Server.Transfer("MyErrorPage.aspx"); w3IU'(|G
uRNc9
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ph1veD<ZZ
} My'6yQL
cE=v566
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 0ID
