接收参数: E_KCNn-f
string a = Request.QueryString("id"); {t};-q!v$j
string b = Request.QueryString("id1"); qE'9QQ>:b

2.为按钮添加对话框 hTP:[w)

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}")

3.删除表格选定记录 1ygpp0IGJ

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() "V{yi!D{<

8.关于日期格式 vX ] Gf4,
@?"h
!fyu
日期格式设定 KN-avu_Ix
DataFormatString="{0:yyyy-MM-dd}" ~)(\6^&=|
vOg#Dqn-
我觉得应该在itembound事件中 Hr$QLtr
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) "Ky; a?Y
<id}<H
9.获取错误信息并到指定页面 1{P'7IEj
tnLAJ+-M
不要使用Response.Redirect,而应该使用Server.Transfer GRY2?'`
$/nY5[
e.g 9uWY@zu
// in global.asax /> 4"~q)
protected void Application_Error(Object sender, EventArgs e) { "O(9 m.CZ
if (Server.GetLastError() is HttpUnhandledException) Zdn~`Q{
Server.Transfer("MyErrorPage.aspx"); "1,pHR-+R
|g*XK6
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;qBu4'C)T
} 4 {9B9={
awz;z?~
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 %Z*sU/^

10.清空Cookie n[(Qr9
Cookie.Expires=[DateTime]; $v Z$'(
Response.Cookies("UserName").Expires = 0 } CfqG?)
