button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") X@x:

3.删除表格选定记录 X~GZI*P
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; FjiLc=RXXz
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() }}t"^m s

5.点击表格行链接另一页 :Oq!.uO

8.关于日期格式 p(Qm\g<
)}u.b-Nt.
日期格式设定 +(|T\%$DT
DataFormatString="{0:yyyy-MM-dd}" nHT2M{R
FirmzB Il5
我觉得应该在itembound事件中 SrHRpxy
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ?J<4IvL/
X0U{9zP
9.获取错误信息并到指定页面 cm7aL%D$c
vhhsOga
不要使用Response.Redirect,而应该使用Server.Transfer uOW9FAW
umls=iz
e.g _/MKU!\l
// in global.asax `7N[rs9|S
protected void Application_Error(Object sender, EventArgs e) { C@Wm+E~;8
if (Server.GetLastError() is HttpUnhandledException) Q>Q$BCD5
Server.Transfer("MyErrorPage.aspx"); \".3x
PkE
a_x|PbD
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) RqcX_x(p
} gCwg ;c-
Z,u:g c+*
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 M>T#MDK\(

10.清空Cookie %W`pTvF
Cookie.Expires=[DateTime]; x%x[5.CT
Response.Cookies("UserName").Expires = 0 40q8,M
