3.删除表格选定记录 RZV1:hNN
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 8Snq75Q<
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ;GSFQ:m[

{ |e-+xX|;
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; SSsQu^A
this.style.color=’buttontext’;this.style.cursor=’default’;"); :Ye#NPOI

8.关于日期格式 s)DNLx
m6Cd^'J9^
日期格式设定 E~@HC 5.M
DataFormatString="{0:yyyy-MM-dd}" l0_E9qh-i
[U7,\o4w
我觉得应该在itembound事件中 OTHd1PSOu
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ^xNe Eb
A&lgiR*ObT
9.获取错误信息并到指定页面 ,N|R/Vk$+E
;7`um
不要使用Response.Redirect,而应该使用Server.Transfer rRG\:<a
K#C56k q&
e.g D*r Zaqy
// in global.asax f}ij=Y9
protected void Application_Error(Object sender, EventArgs e) { pB7Z;&9
if (Server.GetLastError() is HttpUnhandledException) 8YLZ)k'
Server.Transfer("MyErrorPage.aspx"); t5v)6|
GH+FZ (F
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;s
B:s9M
} U W)&Eky
A8Z?[,Mq!
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 *2C79hi1

10.清空Cookie % m5 ^p
Cookie.Expires=[DateTime]; jc~*#\N
Response.Cookies("UserName").Expires = 0 K2o0L5Lke
