1. 打开新的窗口并传送参数: 42J{aJVH

传送参数: RTh`ENCKR
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") <r#eL39I

接收参数: m,UGWR
string a = Request.QueryString("id"); :a

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") , EGQ@:3/

3.删除表格选定记录 w-wV3Q6X
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; PYbVy<xc
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() i0$Bx>

8.关于日期格式
OX\A|$GS
I}1NB3>^
日期格式设定 59h)-^!
DataFormatString="{0:yyyy-MM-dd}" f|\onHI)>
C{U?0!^
我觉得应该在itembound事件中 &5yVxL:
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) H{Wu]C<@p
E=nIRG|g
9.获取错误信息并到指定页面 vSEuk}pk
y*qVc E
不要使用Response.Redirect,而应该使用Server.Transfer As'=tIro
YNQY4\(
e.g <0Xf9a8>
// in global.asax _h{C_;a[_
protected void Application_Error(Object sender, EventArgs e) { sB7#
~pA
if (Server.GetLastError() is HttpUnhandledException) Zy`m!]G]80
Server.Transfer("MyErrorPage.aspx"); h2G$@8t}I
3 2&;`]C
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) M/b Sud?@%
} a<^ v(r
~E17L]ete
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 6 (]Dh;gC
