2.为按钮添加对话框 \vA*dQ-

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") }| DspO

3.删除表格选定记录 !"L.g u-'
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; m{/7)2.
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() C-&ymJC|

6.表格超连接列传递参数 Ca2r<|uA

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; xTHD_?d

8.关于日期格式 ;: ;E|{e
aKI"<%PNn
日期格式设定 y=3 dGOFB
DataFormatString="{0:yyyy-MM-dd}" P>/:dt'GJ}
o@meogkL
我觉得应该在itembound事件中 }d[(kC_
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ^FVdA1~/
i)i>Ulj*i
9.获取错误信息并到指定页面 y{<e4{
!
{[y6qQm
不要使用Response.Redirect,而应该使用Server.Transfer 5!c/J:z
v">?`8V
e.g 1T^WMn:U
// in global.asax -U|c~Cqc
protected void Application_Error(Object sender, EventArgs e) { 9CDei~
if (Server.GetLastError() is HttpUnhandledException) I Xc `Ec
Server.Transfer("MyErrorPage.aspx"); 0z8(9DlTc
Eb3 ZM#
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ]S2rqKB
} )2f#@0SVL
rOJ>lPs
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 u0C:q`;z

10.清空Cookie CK_dEh2c
Cookie.Expires=[DateTime]; j7I=2xnTWu
Response.Cookies("UserName").Expires = 0 R7::f\I
