button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 'VTLp.~G~

3.删除表格选定记录 &%4*~;o
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; *(sFr E
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() gT~Yn~~b

6.表格超连接列传递参数 igD,|YSK`z
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ nrpxZA
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> cKKl\g@}

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; Lh(`9(tX
this.style.color=’buttontext’;this.style.cursor=’default’;"); cj!Ew}o40D

8.关于日期格式 L/VlmN_v>s
^U`Bj*"2
日期格式设定 [;F%6MPK^
DataFormatString="{0:yyyy-MM-dd}" -W:te7
n!B*n(;!u
我觉得应该在itembound事件中 h!L/ZeRaV
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) AMhHq/Dw
/ ao|v
9.获取错误信息并到指定页面 2V1|b`b#4
BSGC.>$s
不要使用Response.Redirect,而应该使用Server.Transfer wewYlm5@
VNmQ'EuV}2
e.g gJ8+HV
// in global.asax fgW>U*.ar
protected void Application_Error(Object sender, EventArgs e) { vThK@P!s
if (Server.GetLastError() is HttpUnhandledException) v{Rj,Ou
Server.Transfer("MyErrorPage.aspx"); o"Dk`L2
!4(X9}a
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 4[ 7)$
} K6=i\
<=D\Ckmb
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 B3lP#ckh

10.清空Cookie avb'J^}f
Cookie.Expires=[DateTime]; BP6|^Q
Response.Cookies("UserName").Expires = 0 [LQD]#
