6.表格超连接列传递参数 b`x7%?Qn
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ P3w]PG@
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 2C9wOO

{ ;aZ$qgN*Y
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ,@+7(W
this.style.color=’buttontext’;this.style.cursor=’default’;"); MQL1 />j;
} ,2Y PD4

写在DataGrid的_ItemDataBound里 f tVA

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ;]ojfR=?%

8.关于日期格式 T [mo
PD5
!PN;XZ~{
日期格式设定 *? /9lAm
DataFormatString="{0:yyyy-MM-dd}" ^i3~i?\,P
owClnp9K
我觉得应该在itembound事件中 _dCsYI%
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) n@pm5f

9.获取错误信息并到指定页面 .&:GOD
m'Jk!eo
不要使用Response.Redirect,而应该使用Server.Transfer +xqPyR
hFORs.L&G
e.g #UR4I2t*
// in global.asax %9z N U
protected void Application_Error(Object sender, EventArgs e) { |meo
if (Server.GetLastError() is HttpUnhandledException) &3x
\wH/_
Server.Transfer("MyErrorPage.aspx"); cY+vnQm
wGd4:W
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) V K/;ohTTP
} "Aw|

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 Lod$&k@@
