response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") FYs)MO
!8 &=y
接收参数: gOgps:
string a = Request.QueryString("id"); 0CSv10Tg
string b = Request.QueryString("id1"); jq'!UN{

2.为按钮添加对话框 dd2[yKC`
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); f= >OJ!:
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") "5cM54Z0

3.删除表格选定记录 }QZQ3@

8.关于日期格式 bwl|0"f+`
S.a%
日期格式设定 |n] d34E
DataFormatString="{0:yyyy-MM-dd}" \7*`}&
y\x+
我觉得应该在itembound事件中 iya"ky~H
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) +[tP_%/r'^
*Aa?yg:=
9.获取错误信息并到指定页面 5+wAzVA
[VWUqlNt>
不要使用Response.Redirect,而应该使用Server.Transfer `Ry]y"K
Kde9
$
e.g x|5k<CiA
// in global.asax 9WR6!.y#f
protected void Application_Error(Object sender, EventArgs e) { &:7ZQ1
if (Server.GetLastError() is HttpUnhandledException) gatB QwJb9
Server.Transfer("MyErrorPage.aspx"); Tq~=TSD
>&U,co$>
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 2j&AiD
} R`~z0d.
fX|Y;S-@+
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 tq|hPd<C
