1. 打开新的窗口并传送参数:
M$-(4 0
bMK'J
传送参数: MdTd$ 4J3
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") m#}{"d&J
GT`<jzAi Q
接收参数: 0T{Y_IG
string a = Request.QueryString("id"); 9[]"%6
string b = Request.QueryString("id1"); gQzJ2LU(
0_xcrM
2.为按钮添加对话框 bU +eJU_%
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); J;]@?(
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") NB6h/0*v
#L*@~M^]
3.删除表格选定记录 H f mMf^c
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; BrH`:Dw
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() }Us$y0W\
@snLE?g j
4.删除表格记录警告 x`|tT%q@l

5.点击表格行链接另一页 '!L1z45
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) ob5nk^y

} /<pQ!'/G

★特别注意:【?id=】 处不能为 【?id =】 |VEAzY|[#
6.表格超连接列传递参数 2/q=l?
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ ]<z(Rmn`Q
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ffd3QQ

7.表格点击改变颜色 0BD((oNg
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) (SVr>|Db
{ 9+Hb`
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ~*]`XL.-
this.style.color=’buttontext’;this.style.cursor=’default’;"); 0lh6b3tdP
} yC*B OJS
1)r _h(
写在DataGrid的_ItemDataBound里 ^TuEp$Z=
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) !#s7 F
{ Rw8m5U
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; !T(Omve)
this.style.color=’buttontext’;this.style.cursor=’default’;"); <5vB{)Tq
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); ;!sGfrs0$
}

8.关于日期格式 s""8V_,;
~o5iCt;w
日期格式设定 PzkXrDlB7
DataFormatString="{0:yyyy-MM-dd}" fsuvg jlE
m6<0 hP
我觉得应该在itembound事件中 ZU'^%)6~o~
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) fOervo
K8c#/o
9.获取错误信息并到指定页面 ,X6j$YLWp
x^skoz
不要使用Response.Redirect,而应该使用Server.Transfer oF^hq-xcP
,lM2BXz%
e.g cBf{R^>Fd
// in global.asax ^C|9K>M
protected void Application_Error(Object sender, EventArgs e) { 8{t&8Ql n
if (Server.GetLastError() is HttpUnhandledException) 6^u(PzlA|~
Server.Transfer("MyErrorPage.aspx"); 5)<jPyC
(.+n1)L?
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) YcZ4y@6"
} MX\-)e#
W/Q%%)J
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 Ls*=mh~IY

10.清空Cookie EIm\!'R]
Cookie.Expires=[DateTime]; XnOl*#P
Response.Cookies("UserName").Expires = 0 M3`A&*\;
