string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ]]|#+$ ~

★特别注意:【?id=】 处不能为 【?id =】 ;BuMzG:tmZ
6.表格超连接列传递参数 &en2t=a
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ |kZ!-?9Z
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 8s22VL

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 9Qszr=C0
this.style.color=’buttontext’;this.style.cursor=’default’;"); |ufT)+:

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; 0WzoI2Q

8.关于日期格式 &n,v@
gt
0`zdj
日期格式设定 oi`L ;w|]
DataFormatString="{0:yyyy-MM-dd}" BcQUD?LC`
-W6@[5 c
我觉得应该在itembound事件中 sDs.da#*2
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ac\aH#J_nC
^6# yL6E,~
9.获取错误信息并到指定页面 +6>2= ,?Z
r1F5'?NZ(0
不要使用Response.Redirect,而应该使用Server.Transfer G\tN(%.f
Pz*BuL<
e.g >!Gq[i0
// in global.asax : F3UJ[V
protected void Application_Error(Object sender, EventArgs e) { W/A@q o"
if (Server.GetLastError() is HttpUnhandledException) sT =|"H?
Server.Transfer("MyErrorPage.aspx"); #}fvjJ{
)'jGf;du
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) K'2N:.D:
} E
1`g8Hk'
KT<i%)t2
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 1/1oT
