1. 打开新的窗口并传送参数: -!1=S: S

接收参数: ?Te#lp;`~
string a = Request.QueryString("id"); 8Re[]bE
string b = Request.QueryString("id1"); IRm}?hHf

2.为按钮添加对话框

Button1.Attributes.Add("onclick","return confirm(’确认?’)"); >S7t
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") k;+TN9

3.删除表格选定记录 l&+O*=#Hh
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; BJux5Nh
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() r{R<J?Y

日期格式设定 9iG&9tB@
DataFormatString="{0:yyyy-MM-dd}" C})Dvh

我觉得应该在itembound事件中 R)66qRf
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ^Ye(b7Gd

9.获取错误信息并到指定页面 m&gd<rt/
3l<qcKKc
不要使用Response.Redirect,而应该使用Server.Transfer ?\8aT"o
kaCN^yQ
e.g Ge`7`D>L
// in global.asax jlP*RX
protected void Application_Error(Object sender, EventArgs e) {
$L= Dky7
if (Server.GetLastError() is HttpUnhandledException) `*vO8v
Server.Transfer("MyErrorPage.aspx"); l48$8Mgrr
'UsR/h5T
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `TJhH<z"%
} ^nPy(Q0
O(W"QY
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 /.0K#J:

10.清空Cookie D-/6RVq0m
Cookie.Expires=[DateTime]; ;F258/J
Response.Cookies("UserName").Expires = 0 A8&@Vxdz

11.自定义异常处理 k";dK*hD,
