接收参数: T:=ST3#m
string a = Request.QueryString("id"); Jk>!I\
string b = Request.QueryString("id1"); "J"RH:$v

6.表格超连接列传递参数 NInZ~4:
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ YB.@zL0.(
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> UAGh2?q2

8.关于日期格式 WLiF D.
h]/3doP
日期格式设定 `dhBLAt
DataFormatString="{0:yyyy-MM-dd}" 7rG+)kHG
jhJ<JDJ?`
我觉得应该在itembound事件中 FiSx"o
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 53>(2 _/[r
7~);,#[ky
9.获取错误信息并到指定页面 #J t1AV
K"ly\$F
不要使用Response.Redirect,而应该使用Server.Transfer
WJ,? 5#
u8gqWsvruM
e.g yCuLo`
// in global.asax IC1nR
u2I
protected void Application_Error(Object sender, EventArgs e) { M(I%QD
if (Server.GetLastError() is HttpUnhandledException) z]D/Qr
Server.Transfer("MyErrorPage.aspx"); MI-S}Qoe
<$ qT(3w<y
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) '}:(y$9.`
} ia,5=SKJ
'6\ZgOO9
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 wd3OuDrU

10.清空Cookie EMpq+LrN
Cookie.Expires=[DateTime]; *3s-=.U~
Response.Cookies("UserName").Expires = 0
