5.点击表格行链接另一页 [~J4:yDd=
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) N9i>81tY

//点击表格打开 .{Xi&[jw

★特别注意:【?id=】 处不能为 【?id =】 4Fnr8 r8W
6.表格超连接列传递参数 ^@N@gB
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ fQv^=DI#
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> L:S[QwQu8

7.表格点击改变颜色 O=yUAAD$
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) Ly^r8I
{ z- ()7WY
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; k:c)|2
this.style.color=’buttontext’;this.style.cursor=’default’;"); Oh|Hy/&6W
} j/9'L^]
M[X& Q
写在DataGrid的_ItemDataBound里 8&3G|m1-2
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) m:'fk;khN
{ @P%&Dha
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; wL}=$DN

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); M*t{?o/t;
} [1N*mY;

8.关于日期格式 chxO*G
<Q%\pAP}b
日期格式设定 (pAGS{{
DataFormatString="{0:yyyy-MM-dd}" lwa
Peb;XI
我觉得应该在itembound事件中 IAg#YFI
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) GUMO;rZs

9.获取错误信息并到指定页面 z0c_&@uj*
8)T.[AP
不要使用Response.Redirect,而应该使用Server.Transfer >R
:Bkf-
O[$&]>x]]
e.g 8E|S`I
// in global.asax (A?/D!y
protected void Application_Error(Object sender, EventArgs e) { wVp
if (Server.GetLastError() is HttpUnhandledException) edA.Va|0
Server.Transfer("MyErrorPage.aspx"); :dB6/@fW
x%0Q W
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 40mgB4I
} m&fm<?|
U"/":w ~
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 ?&"-y)FG
