接收参数: zp4ru\
string a = Request.QueryString("id"); CI{]o&Tf
string b = Request.QueryString("id1"); MVt#n\_BZV

2.为按钮添加对话框 .?I!/;=[
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); iZMsN*9[
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") #-'}r}1ZT

8.关于日期格式 s Y6'y'a95
5rWRE-
日期格式设定 =
]@xXVf/
DataFormatString="{0:yyyy-MM-dd}" )/ZSb1!
ZF
t^q/pw
我觉得应该在itembound事件中 ..T(9]h
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) |X.z|wKT6
q#a21~S<
9.获取错误信息并到指定页面 ,9pi9\S
v8@dvT<
不要使用Response.Redirect,而应该使用Server.Transfer :RQ[(zD]
7_3O]e[8
e.g "J.jmR;
// in global.asax Tk!b`9
protected void Application_Error(Object sender, EventArgs e) { `o3d@Vc
if (Server.GetLastError() is HttpUnhandledException) \k,bz0
Server.Transfer("MyErrorPage.aspx"); M/DTD98'N
:3t])mL#
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) h0eo:Ahi
} j41:]6
z
K(5&u
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 "EHc&,B`

10.清空Cookie bn`zI~WS
