6.表格超连接列传递参数 VI`x

<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ xX.Ox
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> Mhw\i&*U

7.表格点击改变颜色 Zb#
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) \:?H_^^d
{ ]H|1quT
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; .*g;2.-qv&
this.style.color=’buttontext’;this.style.cursor=’default’;"); br'/>Un"
} 2'r8#,)
_?2xIo
写在DataGrid的_ItemDataBound里 GS3ydN<v
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 2WOdTM{u
{ 7iKbd
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; XfT6,h7vFL
this.style.color=’buttontext’;this.style.cursor=’default’;"); L3~E*\cV
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); .ODtduURe
} Cst>'g-yB

8.关于日期格式 q 9pcEm4?
!J'xk
日期格式设定 ;SVF"Uo
DataFormatString="{0:yyyy-MM-dd}" i9M6%R1m}E
Ve8`5
我觉得应该在itembound事件中 [P{Xg:0
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 4"j5@bppJ
}H,A

9.获取错误信息并到指定页面 ()>\D
EX&y
!
不要使用Response.Redirect,而应该使用Server.Transfer 8YN+
\
8LwbOR"
e.g 9H3#8T] ;
// in global.asax sEvJ!$Tt?I
protected void Application_Error(Object sender, EventArgs e) { }%R6Su]y
if (Server.GetLastError() is HttpUnhandledException) xt"/e-h}
Server.Transfer("MyErrorPage.aspx"); ^j=_=Km]
r/O(EW#=8
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) tY:-13F
} )-a_,3x%j

)j%]zd2
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 Z?hBn`.
