button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") R*0]*\C z

3.删除表格选定记录 "`Q&s
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; Ui?iMtDr
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ~(*2:9*0

e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); fn#qcZv?

★特别注意:【?id=】 处不能为 【?id =】 5^D094J|^
6.表格超连接列传递参数 ,eGguNA9
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ GKc?
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 7KesfH?

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; C7O8B;
this.style.color=’buttontext’;this.style.cursor=’default’;"); S B~opN
} zLgc j(;

写在DataGrid的_ItemDataBound里 +e^CL#Gs

{ Qr\eT}
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; +BeA4d8b

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); 0W0GSDx

8.关于日期格式 "cyRzQ6EH
iX o(
日期格式设定 -AD@wn!wCJ
DataFormatString="{0:yyyy-MM-dd}" K@<*m!%<2
_TLspqi
我觉得应该在itembound事件中 Nw9@E R
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ~s-bA#0S
7]} I
9.获取错误信息并到指定页面 R?zlZS.~
idB1%?<
不要使用Response.Redirect,而应该使用Server.Transfer oi
m7=I0
wmww7
e.g \q?^DI:`
// in global.asax el U %Z9
protected void Application_Error(Object sender, EventArgs e) { w$IUm_~waa
if (Server.GetLastError() is HttpUnhandledException) 4#{f8
Server.Transfer("MyErrorPage.aspx"); t{g@z3
L(bDk'zi
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) v4Wq0>o
} ]
)iP?2{
>fMzUTJ4
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 d5NE:%K

10.清空Cookie tA^+RO4
Cookie.Expires=[DateTime]; T$`m!mQ4
Response.Cookies("UserName").Expires = 0 S{?l/*Il*_
