3.删除表格选定记录 aj+zmk~-
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; :

6.表格超连接列传递参数 .F=<r-0

{ o>QFdx
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; DT1i2!
this.style.color=’buttontext’;this.style.cursor=’default’;"); Gff[c%I
} 8=u+BDG

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); hc31+TL

8.关于日期格式 )e <! =S
r5fz6"
日期格式设定 eO[Cb]Dy:
DataFormatString="{0:yyyy-MM-dd}" bo?3E +B
]CtoK%k
我觉得应该在itembound事件中 d"e%tsj
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Q'%5"&XFD

9.获取错误信息并到指定页面 nP3;<*T P0
/d]V{I~6
不要使用Response.Redirect,而应该使用Server.Transfer bl!f5RO S(
GhfUCW%
e.g N4JqW
// in global.asax Q,`2DHhK
protected void Application_Error(Object sender, EventArgs e) { v1tN
DyM6
if (Server.GetLastError() is HttpUnhandledException) 6{,K7FL
Server.Transfer("MyErrorPage.aspx"); dp%pbn6w
G\aLg
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) y:|Xg0Kp
} J,77pf!B
]oWZ{#r2
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 :6Pc m3

10.清空Cookie Q i'WV9ke
