1. 打开新的窗口并传送参数: :5@7z9 >
`{tykYwCLc
传送参数: -Ca.:zX
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") RZ?>>Ll6

接收参数: _>3GNvS
string a = Request.QueryString("id"); G?jY>;P)
string b = Request.QueryString("id1"); FVF:1DT

e?6
2.为按钮添加对话框 frGUT#9?n
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); (S9"(\A
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") XV+BSW7}
i<=@7W
3.删除表格选定记录 X

int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; _$Z46wHmB
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() r>osa3N'

8.关于日期格式 O#k?c }
hcN$p2-
日期格式设定 `qfVgT=2
DataFormatString="{0:yyyy-MM-dd}" jj.yB#T
g5T~%t5lo
我觉得应该在itembound事件中 67n1s
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) c)$/Uu
'nCBLc8
9.获取错误信息并到指定页面 .Qi`5C:U
D/{-
不要使用Response.Redirect,而应该使用Server.Transfer R'9TD=qEK
Gt 2rJ<>
e.g }. ,xhF[
// in global.asax .t~I[J\<
protected void Application_Error(Object sender, EventArgs e) { f'#7i@Je
if (Server.GetLastError() is HttpUnhandledException) n
P 69W
Server.Transfer("MyErrorPage.aspx"); wefQmRK
@&2T0UB
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) !(o)*S
} !\"C<*5
!CsoTW9C:
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 SJy? ^
