1. 打开新的窗口并传送参数: w)S 4Xi=
dL4VcUS.
传送参数: |Tmug X7
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") J&h59dm-
}*9F `=%F
接收参数: PtUS7[]
string a = Request.QueryString("id"); a'Cny((
string b = Request.QueryString("id1"); $H3C/|
dkEbP*yXg
2.为按钮添加对话框 8g{Mv#b%
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); Ygg+=@].@
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") ;8vB7|54.

3.删除表格选定记录 UGM:'xa<T
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 9=iMP~?xF
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Q`J U[nY

6.表格超连接列传递参数 mDwuJf8}
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ 8EiS\$O-

{ Vfq-H /+
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 3M[d6@a

8.关于日期格式 :=quCzG
Y.52`s6F
日期格式设定 8*VQw?{Uee
DataFormatString="{0:yyyy-MM-dd}" c2gZ<[~
NSx-~)
我觉得应该在itembound事件中 )TNG0[
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) qMO(j%N5
0yUn~'+(Sp
9.获取错误信息并到指定页面 iy8Ln,4z(
>"zN`
不要使用Response.Redirect,而应该使用Server.Transfer 7|ACJv6%9
lYm00v6y
e.g 0|\A5
eG
// in global.asax nGJ+.z
protected void Application_Error(Object sender, EventArgs e) { c;
1f$$>b
if (Server.GetLastError() is HttpUnhandledException) 'vZWkeo
Server.Transfer("MyErrorPage.aspx"); [w FK!?
_lH:%E*
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) JsX}PVuL
} (c3O> *M
,k:>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 mX@xV*

10.清空Cookie FYg{IKg
Cookie.Expires=[DateTime]; 77]Fp(uI
Response.Cookies("UserName").Expires = 0 6%c]{eTd9

11.自定义异常处理 ?%>S5,f_
