button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") a*;b^Ze`v

3.删除表格选定记录 /reX{Y
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; u2I Cl
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() @HW*09TG

6.表格超连接列传递参数 D0Cy^_
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ IB<d
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> t

7.表格点击改变颜色 q;U,s)Uz^
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) sGb{9.WK

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; GL JMP^p
this.style.color=’buttontext’;this.style.cursor=’default’;"); &{RDM~

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; .o8t+X'G

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); eq" ]%s

8.关于日期格式 bfO=;S]b!
`kr?j:g
日期格式设定 a>)f=uS
DataFormatString="{0:yyyy-MM-dd}" w:l"\Tm
<or2
我觉得应该在itembound事件中 W l16`9
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) -DCbko
yBRC*0+Vy
9.获取错误信息并到指定页面 m3ff;,
{^'HL
不要使用Response.Redirect,而应该使用Server.Transfer 4~=l}H>&
0ksa
e.g ?}7p"3j'z
// in global.asax <| &Npd'
protected void Application_Error(Object sender, EventArgs e) { ,
dp0;nkr
if (Server.GetLastError() is HttpUnhandledException) 5coZ|O&f8
Server.Transfer("MyErrorPage.aspx"); rH>)oThA#
875od
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) zT[!o
j7
} smLQS+UE
*j-aXN/ $
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 &0f,~ /%Z

10.清空Cookie 2JFpZU"1
Cookie.Expires=[DateTime]; 2-b6gc7
Response.Cookies("UserName").Expires = 0 =mGez )T5\
