1. 打开新的窗口并传送参数: -G|?Kl

接收参数: Lo{g0~?x*
string a = Request.QueryString("id"); ORdS|y;:
string b = Request.QueryString("id1"); a7~%( L@r

2.为按钮添加对话框 9P7^*f:E

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") ;"R1>tw3)

3.删除表格选定记录 1+Z@4;fk
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; cOa){&u
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() x 8_nLZ

8.关于日期格式 z>A;|iL
WCL#3uYk"
日期格式设定 0o]T6
DataFormatString="{0:yyyy-MM-dd}" n>L24rL
3ahbv%y
我觉得应该在itembound事件中 i0g/'ZP
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) I2^@>/p8\(
qL2Sv(A Z!
9.获取错误信息并到指定页面 kj]m@mS[
du>d ?
不要使用Response.Redirect,而应该使用Server.Transfer 2"pFAQBw~i
tBtmqxx
e.g #V U>Z|$@N
// in global.asax D`hg+64}
protected void Application_Error(Object sender, EventArgs e) { 8\BYm|%aa
if (Server.GetLastError() is HttpUnhandledException) ^CfWLL&
c
Server.Transfer("MyErrorPage.aspx"); #'fQx`LV
Tr$37suF
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 3hPp1wZd
} K0^Tg+U($p
?!;i/h*{
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 f=kt0
