1. 打开新的窗口并传送参数: 1EC;t1.7
+'MO$&6
传送参数: ;Oqf{em];
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") ']+!i a
CmBgay
接收参数: >P\eHR,{-
string a = Request.QueryString("id"); c_M[>#`
string b = Request.QueryString("id1"); jWi~Q o+
BmccSC;o4
2.为按钮添加对话框 :
xggo
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); "e8EA!Ipte
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") qBh@^GxY),
oSkQ/5hg.
3.删除表格选定记录 bR~(Ry`
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; _;Xlw{FN^
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Nq8 3 6HL

5.点击表格行链接另一页 CrL9|78
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) ]BbV\#

//点击表格打开 CLVT5pj='
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) _|0#
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); &dmIv[LU

6.表格超连接列传递参数 0[%{YmI{W
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ ||pOiR5
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> W$SV+q(rT

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) Ea<\a1Tl43
{ 9=]HOUn
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; [qRww]g;P|
this.style.color=’buttontext’;this.style.cursor=’default’;"); H7&y79mB

写在DataGrid的_ItemDataBound里 ^"

8.关于日期格式 :6t73\O
h;+O96V4.
日期格式设定 >TCit1yD
DataFormatString="{0:yyyy-MM-dd}" dO1m
PDA9.b<q0
我觉得应该在itembound事件中 E.NfVeq
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) RxJbQs$Ph

9.获取错误信息并到指定页面 UMd.=HC L
fcF| m5
不要使用Response.Redirect,而应该使用Server.Transfer S>(x x"Ia
FO^6c
e.g Oi: Hs
// in global.asax 8Y RT0/V
protected void Application_Error(Object sender, EventArgs e) { WR#h~N
9c
if (Server.GetLastError() is HttpUnhandledException) &(,&mE
Server.Transfer("MyErrorPage.aspx"); 2D"my]FnF
`V V>AA5
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) J9NuqV3
} #'%ii,;wQ
NwYQ6VEA
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 M\CzV$\y

10.清空Cookie Y1sK sdV
Cookie.Expires=[DateTime]; ,#,K_oz
Response.Cookies("UserName").Expires = 0 ?87\_wL/j

11.自定义异常处理 F3!@|/<w
