5.点击表格行链接另一页 @H7d_S
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) F{~{Lthc
{ _Wq
//点击表格打开 cacr=iX
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) %'7lbpy,f
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); WR yaKM

6.表格超连接列传递参数 dx&'fe*?
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ `YLD`(\
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> D=m9fFz

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; )d1_Wm#B
this.style.color=’buttontext’;this.style.cursor=’default’;"); ,PuL{%PXu

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ,dov<U[ia

8.关于日期格式
1 +qw$T
/!Wu D\B
日期格式设定 }Q?c"H!/
DataFormatString="{0:yyyy-MM-dd}" f3&[#%
iZNts%Y]
我觉得应该在itembound事件中 D 38$`j
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Y/>&0wj)d

9.获取错误信息并到指定页面 ZP*q4:
"B4;,+4kR
不要使用Response.Redirect,而应该使用Server.Transfer 2`>T oWN!
9{}1r2xW
e.g wEE\+3b)
// in global.asax *:t|qgJI#+
protected void Application_Error(Object sender, EventArgs e) { p|jV{P
if (Server.GetLastError() is HttpUnhandledException) Wi2WRJdyu
Server.Transfer("MyErrorPage.aspx"); ,^;)<[
=aA+~/~8%
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) =aj/,Q]
} X*39c
b(b
O-cbX/d
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

10.清空Cookie ,M6Sy]Aj
Cookie.Expires=[DateTime]; #qI= Z0Y
Response.Cookies("UserName").Expires = 0 {u\Mj
