1. 打开新的窗口并传送参数: #Xi9O.

传送参数: UQBc$`v
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") tR?)C=4,

接收参数: qt.=
string a = Request.QueryString("id"); * YLpC^&
string b = Request.QueryString("id1"); d(, M

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") U@LIw6B!KL

3.删除表格选定记录 T^2o'_:
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; =o[H2o
y
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() {t('`z

日期格式设定 p ^ )iC&*0

9.获取错误信息并到指定页面 bfKF6
=dY!-#yg!
不要使用Response.Redirect,而应该使用Server.Transfer KKNQ+'?
8]l(D
e.g \s,~|0_V
// in global.asax $u::(s}
x<
protected void Application_Error(Object sender, EventArgs e) { 7K
/qu J
if (Server.GetLastError() is HttpUnhandledException) c{})Z=
Server.Transfer("MyErrorPage.aspx"); hfRxZ>O2
SH6T\}X:
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) i:
VMCNH
} IkgRZ{Y
`4a9<bG
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 v}Kj+9h
