★特别注意:【?id=】 处不能为 【?id =】 y=e|W=<D&
6.表格超连接列传递参数 RZ9chTX/
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ G8CM
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> -H](2}

7.表格点击改变颜色 {dNWQE*\c
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) =(as{,j
{ {r[g.@
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; fJOA5(
this.style.color=’buttontext’;this.style.cursor=’default’;"); ,uhOf! |
} pM_oIH'8:

8.关于日期格式 JQ"w{O
>Byxb./*
日期格式设定 0r'<aA`=I
DataFormatString="{0:yyyy-MM-dd}" !:<n]-U
^@AIXBe
我觉得应该在itembound事件中 <lHVch"(^$
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /UPe@

9.获取错误信息并到指定页面 \6c8Lqa
g/e2t=qP
不要使用Response.Redirect,而应该使用Server.Transfer EPGp8VGXp~
IO]%AL(.;
e.g HD{2nZT
// in global.asax tU>?j1
protected void Application_Error(Object sender, EventArgs e) { yM*f}S/
(
if (Server.GetLastError() is HttpUnhandledException) qK12:
Server.Transfer("MyErrorPage.aspx"); 5AO'Ihp L
^Jdji:
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) s^Rig[
} X) xeq
};s8xGW:k3
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 a+ lGN

10.清空Cookie z~O:w'(g
Cookie.Expires=[DateTime]; 3zuYN-;
Response.Cookies("UserName").Expires = 0 S{F'k;x/5
