1. 打开新的窗口并传送参数: `p|{(g'
<=W;z=$!Bb
传送参数: 2E9Cp
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") #tRLvOR:
t5\~Z}G8
接收参数: <w}YD @(f
string a = Request.QueryString("id"); MRMswNQ
string b = Request.QueryString("id1"); E=_M=5]
Mm;kB/1
2.为按钮添加对话框 Jlj=FA`
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); %oJ_,m_(
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") se:]F/

3.删除表格选定记录 5Q;Fwtm
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; e23}'qb
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() {0 IEizQ|i
h# c.HtVE
4.删除表格记录警告 %AwR 4"M

5.点击表格行链接另一页 .Zv@iL5
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) `dO)}}| y
{ Xxhzzm-B
//点击表格打开 00X~/'!
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) Wnm?a!j5
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); a NhI<.v

双击表格连接到另一页 Y3KKskhLx

★特别注意:【?id=】 处不能为 【?id =】 *S ,5
6.表格超连接列传递参数 mux_S2x9m\
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ nW#UBtZ
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> *-0tj~)>

7.表格点击改变颜色 4&]Sb}
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) `L n,qiA
{ .;nU"

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; I.#V/{J
this.style.color=’buttontext’;this.style.cursor=’default’;"); n3Uw6gLD

写在DataGrid的_ItemDataBound里 ^~\cx75D

{ Ldqn<wNnI
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; j_YpkKhen

8.关于日期格式 9C9>V]
3Ov? kWFO
日期格式设定 tgeX~.
DataFormatString="{0:yyyy-MM-dd}" #( G>J4E,
aLa{zB
我觉得应该在itembound事件中 +$_.${uwV
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) }e[;~g\&
W\f u0^
9.获取错误信息并到指定页面 N1dv}!/*.+
B'sgCU
不要使用Response.Redirect,而应该使用Server.Transfer R)}ab{A
pgNyLgN
e.g oZVq}}R
// in global.asax nKxu8YAJe
protected void Application_Error(Object sender, EventArgs e) { YKCd:^u
if (Server.GetLastError() is HttpUnhandledException) :g@H=W
Server.Transfer("MyErrorPage.aspx"); ,gY bi-E
NHI(}Ea|]
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Js{X33^Ju
} y$-;6zk\]
0_\@!#-sml
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 m3Ma2jLWC

10.清空Cookie 1dsMmD[O
Cookie.Expires=[DateTime]; $Sg5xkV,a
Response.Cookies("UserName").Expires = 0 E(%_aFx>/
