1. 打开新的窗口并传送参数: -hd@<+;E

传送参数: Jy^.L$bt
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") ey/{Z<D

接收参数: 9~7s*3zI
string a = Request.QueryString("id"); 8]@$7hy8
string b = Request.QueryString("id1"); 19h@fA[:

2.为按钮添加对话框 Ji#eA[
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); ax)>rP,V
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") T]_]{%z

3.删除表格选定记录 ]z77hcjB1
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; cFD3
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() _O,k0O

8.关于日期格式 D}`MY\H
NY6;\ 7!n
日期格式设定 T/PmT:Qg`
DataFormatString="{0:yyyy-MM-dd}" ?3%r:g4
y>X(GF^
我觉得应该在itembound事件中 VHi'~B#'*
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) *P/DDRq(2

9.获取错误信息并到指定页面 >K<cc#Aa
B7wzF"
不要使用Response.Redirect,而应该使用Server.Transfer 29^(weT"]
e'sS",o*
e.g i#aKW'
// in global.asax o)GesgxFa5
protected void Application_Error(Object sender, EventArgs e) { +Ks 3
if (Server.GetLastError() is HttpUnhandledException) "rrw~
Server.Transfer("MyErrorPage.aspx"); ]9-iEQ
PXG@]$~3
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) z(u,$vZ_
} r>}z|I'
v|KGzQx$.*
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 nvCp-Z$

10.清空Cookie &;bey4_J
Cookie.Expires=[DateTime]; ,9M2'6=
