2.为按钮添加对话框 y#4f^J!V
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); l(EDe
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") F__j]}?

5.点击表格行链接另一页 cR/-FR
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) K,uTO7Mk[
{ wT;3>%Mtr
//点击表格打开 DAZzc :1Aj
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) g_kR5Wxpt

双击表格连接到另一页 {u3eel

在itemDataBind事件中 8VbHZ9Q

★特别注意:【?id=】 处不能为 【?id =】 wv.FL$f[@
6.表格超连接列传递参数 !ke_?+8sY
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ l>l)m-;O
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> aNZJs<3;'D

7.表格点击改变颜色 yv.Y-c=
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) eBZa9X$
{ cY%[UK $l
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; c\X0*GX
this.style.color=’buttontext’;this.style.cursor=’default’;"); 'dE G\?v9
} q+A^JjzT
?vHow$
写在DataGrid的_ItemDataBound里 q4].C|7
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) KmuE#Ia
{ ~Wh}W((L
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; qo1eHn4

8.关于日期格式 bU`Ih# q
Vb${Oy+
日期格式设定 +&LzLF.bK
DataFormatString="{0:yyyy-MM-dd}" Va^AEuzF
Sq9I]A
我觉得应该在itembound事件中 VieX5
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) O>zPWVwa

9.获取错误信息并到指定页面 F-!,U)
7qfo%n"
不要使用Response.Redirect,而应该使用Server.Transfer w28!Yj1Q
,2Y PD4
e.g 4@,d{qp~
// in global.asax GCN(
protected void Application_Error(Object sender, EventArgs e) {
Vf:w.G A
if (Server.GetLastError() is HttpUnhandledException) JCjQR`)
Server.Transfer("MyErrorPage.aspx"); ]+1?T)<!
ENlqoj1
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) IR*g>q
} goYRA_%cX
U.7;:W}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 X~/hv_@

10.清空Cookie n^8LF9r
Cookie.Expires=[DateTime]; #;Yn8'a~
Response.Cookies("UserName").Expires = 0 u{0'"jVJ
