1. 打开新的窗口并传送参数: Em.?
$1@{Zz!S
传送参数: ta4<d)nB
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") ,[hJi3xM

接收参数: D 7E^;W)H
string a = Request.QueryString("id"); F^~#D, \
string b = Request.QueryString("id1"); fu&]t8MJC
nW%c95E
2.为按钮添加对话框 1Q$ M/}
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); _1JvA-
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") q.X-2jjpx:
6%xl}z]o
3.删除表格选定记录 QtzHr
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 4%{m7CK}
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() *ZEs5`x

6.表格超连接列传递参数 $ Zr,-

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; *

8.关于日期格式 "lf3hWGw
z_@zMLs
日期格式设定 v!A|n3B]p
DataFormatString="{0:yyyy-MM-dd}" d
A{Jk
{C6;$#7P
我觉得应该在itembound事件中 ot#kU 8f
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) :w%bw\}
/ASI0h
9.获取错误信息并到指定页面 lG>e6[Wc
m?$G(E5
不要使用Response.Redirect,而应该使用Server.Transfer }Xv1KX'
@(fY4]K
e.g Zb;$ZUWQX
// in global.asax C&N4<2b
protected void Application_Error(Object sender, EventArgs e) { [Od9,XBa
if (Server.GetLastError() is HttpUnhandledException) v=1S
Server.Transfer("MyErrorPage.aspx"); >0#q!H,X
bCUh^#]x
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ky$:C,1t
} b2%bgs
Yka&Kkw
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 k+GnF00N^8

10.清空Cookie h_GBx|c
Cookie.Expires=[DateTime]; DeQ'U!?+N
Response.Cookies("UserName").Expires = 0 T)f_W
