1. 打开新的窗口并传送参数: 0q-lyVZ^X

传送参数: >L4F'#I
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") l$9k:#\FD

接收参数: FVrB#Hw~
string a = Request.QueryString("id"); +<F3}]]
string b = Request.QueryString("id1"); PLs`Ci|`

2.为按钮添加对话框 E\s1p:%
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); y _"V=:
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") Q}lCQK/g

3.删除表格选定记录 >(igVaZ>
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; q 9xA.*
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ^#Q-?O

4.删除表格记录警告 )/)u.$pi

5.点击表格行链接另一页 [=jZP,b&),
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) q%kCTw
{ Sj(>G;
//点击表格打开 N^[
F+y
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) mm:TR?^
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); }'x)e

6.表格超连接列传递参数 m"Mj3Z:
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ r4iNX+h?V
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> V||b%Cb1g

7.表格点击改变颜色 =

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) \ [[xyd
{ )JTQZ,f3]
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ZJ2

this.style.color=’buttontext’;this.style.cursor=’default’;"); Het"x
} oA-,>:}g{

写在DataGrid的_ItemDataBound里 ,iao56`E

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; U'" #jT

8.关于日期格式 ?C fQwY#N
AeEdqX)
日期格式设定 71[?AmxV
DataFormatString="{0:yyyy-MM-dd}" 2=K|kp5
sHBTB6)lx
我觉得应该在itembound事件中 d]sqj\Q57
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) -n|>U:
AzJ;EtR
9.获取错误信息并到指定页面 o[Qb/ 7
*l
=f=
不要使用Response.Redirect,而应该使用Server.Transfer \f4rA?+f
(kY0<
e.g S"G(_%
// in global.asax PA
ZjA0d
protected void Application_Error(Object sender, EventArgs e) { g4,ldr"D
if (Server.GetLastError() is HttpUnhandledException) 8=Oym~
Server.Transfer("MyErrorPage.aspx"); "!vY{9,
n!Y_SPg
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 80Hi v
} g!_#$az3
%JSRC<,a
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 O(%6/r`L,k

10.清空Cookie Gu$J;bXVj
Cookie.Expires=[DateTime]; e6_8f*o|s
Response.Cookies("UserName").Expires = 0 %"(HjanH
