1. 打开新的窗口并传送参数: %HpTQ

传送参数: <{JHFU`^
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") !Yz~HO,u+
'cu(
Sd}
接收参数: Gmf.lHr$%
string a = Request.QueryString("id"); y/'2WO[
string b = Request.QueryString("id1"); It!PP1$

2.为按钮添加对话框 p3 qlVE
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); 4hr;k0sD
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") #swzZyM$

3.删除表格选定记录 .TSj8,
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; n'U*8ID
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() "9>~O`l,

★特别注意:【?id=】 处不能为 【?id =】 F #Uxl%h
6.表格超连接列传递参数 >eQ;\j
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ (YVl5}V

7.表格点击改变颜色 `C%,Nj
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) : ~"^st_[!
{ =QHW>v
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; }QU9+<Z[r
this.style.color=’buttontext’;this.style.cursor=’default’;"); }L^Yoq]
} IsxPm9P2<
(cAv :EKpo
写在DataGrid的_ItemDataBound里 +Pd&YfU9
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) _A|1_^[G(
{ z6#N f,
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; eS8tsI

8.关于日期格式 O&.^67\|
M7-piRnd4
日期格式设定 <"{Lv)4
DataFormatString="{0:yyyy-MM-dd}" aR6?+`6<
O@{ JB
我觉得应该在itembound事件中 :0$(umW@I"
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) yw^t6E
_v{,vLH
9.获取错误信息并到指定页面 6^F"np{w
;2q;RT`h
不要使用Response.Redirect,而应该使用Server.Transfer M p:c.
M8X*fYn
e.g / tM<ois*
// in global.asax K++pH~o
protected void Application_Error(Object sender, EventArgs e) { $,otW2:)
if (Server.GetLastError() is HttpUnhandledException) t_6sDr'.
Server.Transfer("MyErrorPage.aspx"); EGO;g^,
)_"Cz".|9
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;X<#y2`
} 7Oe |:Z
w~y+Pv@
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 rVowHP

10.清空Cookie fIN8::Cs[
Cookie.Expires=[DateTime]; rpu9
Response.Cookies("UserName").Expires = 0 M >P-0IC
