接收参数: Iyyo3awc
string a = Request.QueryString("id"); 0/Z

string b = Request.QueryString("id1"); IE;\7r+h
Qs l80~n_7
2.为按钮添加对话框 Q_]~0PoH
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); Ux}W&K/?'
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") |gv{z"

3.删除表格选定记录 FaY_0G;y
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; \0?$wIH?
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 3+>OGwfQ

6.表格超连接列传递参数 I ~$1Lu`~

8.关于日期格式 Or0O/\D)
M.[rLJZ4
日期格式设定 ,S&z<S_
DataFormatString="{0:yyyy-MM-dd}" rwf^,r"r
6b=q-0yj
我觉得应该在itembound事件中 L'Q<>{;Ig
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) =,V|OfW
v=?2S
9.获取错误信息并到指定页面 5@!st
-e]7n*}H$
不要使用Response.Redirect,而应该使用Server.Transfer z#6?8y2-
IV `%V+
f
e.g D(]E/k@;~
// in global.asax &
,hr8
protected void Application_Error(Object sender, EventArgs e) { \6!W05[ Q
if (Server.GetLastError() is HttpUnhandledException) A1i!F?X
Server.Transfer("MyErrorPage.aspx"); DAO]uh{6
Jn&7C
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Mps5Vv
} pv,45z0
5h{`<W
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 +-$Ko fnM

10.清空Cookie 19UN*g3(
Cookie.Expires=[DateTime]; u bW]-U=T
Response.Cookies("UserName").Expires = 0 xTz%nx
