1. 打开新的窗口并传送参数: Rou$`<{H
8r"$o1!
传送参数: .iK{=L/(y
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") QLNQE 6-

接收参数: {&tbp
Bl#
string a = Request.QueryString("id"); +
3+^J?N
string b = Request.QueryString("id1"); fq*.4s
#
?-"xP'#
2.为按钮添加对话框 "4W@p'
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); RU}
M&&
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") k-5Enbkr
0*?/s\>PS;
3.删除表格选定记录 EW;R^?Z
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; a.P7O!2Lp
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() _-^bAr`z

★特别注意:【?id=】 处不能为 【?id =】 CXqU<a&
6.表格超连接列传递参数 )6?(K"T

<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> dZnAdlJ

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

8.关于日期格式 ?m3,e&pB5
xA|72!zk0P
日期格式设定 Fl,(KSTz
DataFormatString="{0:yyyy-MM-dd}" c}9.Or`?
n(-1vN
我觉得应该在itembound事件中 UEeD Nl$^u
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 3nVdws
96fzSZS,
9.获取错误信息并到指定页面 r|rOIAo
YEGRM$'`
不要使用Response.Redirect,而应该使用Server.Transfer 9I0}:J;7
?#|Y'%a"
e.g M7R.?nk
// in global.asax J!sIxwF
protected void Application_Error(Object sender, EventArgs e) { 'bN\8t\S
if (Server.GetLastError() is HttpUnhandledException) jOs&E^">&B
Server.Transfer("MyErrorPage.aspx"); B%95M|
x:bJ1%
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) o"F=3b~:n
} 1`1U'ibhe
2CX'J8Sy
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 (ly4[G1y

10.清空Cookie $bQ[H[4l
Cookie.Expires=[DateTime]; @d imZsi1
Response.Cookies("UserName").Expires = 0 w}="}Cb
