接收参数: W55kR.X6M
string a = Request.QueryString("id"); lD#

//点击表格打开 ' XOWSx;Y
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) .k,,PuP

6.表格超连接列传递参数 FRsp?i

写在DataGrid的_ItemDataBound里 #L&/o9|

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; bEmzigN[

8.关于日期格式 &}\{qFD;
e7plL^^`
日期格式设定 {`(MK6D8 c
DataFormatString="{0:yyyy-MM-dd}" Q% ^_<u
K#VGG,h7Y
我觉得应该在itembound事件中 x{/-&`F
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ^AERGB\36

9.获取错误信息并到指定页面 9_~9?5PU
3_]QtP3
不要使用Response.Redirect,而应该使用Server.Transfer Y=y
0`?K
T&}KUX~Q/
e.g +RnWeBXAT
// in global.asax FtlJ3fB@
protected void Application_Error(Object sender, EventArgs e) { Xe(]4Ux
if (Server.GetLastError() is HttpUnhandledException) MPF({Pnx7
Server.Transfer("MyErrorPage.aspx");
b`f6(6
AoK;6je`K^
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) dux_v"Xl
} :Y4Sdj
fA=Lb^,M
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 BgY|v
