1. 打开新的窗口并传送参数: fXF=F,!t
E !Oz|q
传送参数: :>tF_6
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") S|{Yvyp
{UX"Epd);n
接收参数: KD,^*FkkL
string a = Request.QueryString("id"); AMh37Xo
string b = Request.QueryString("id1"); r%Q8)nEo
.\ ;l-U
2.为按钮添加对话框 f7_\).T
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); ="5k\1W1M
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") r/N[7*i
|aI|yq)
3.删除表格选定记录 IL+#ynC
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; XI%RneuDr:
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() +X* F<6mZ
' D)1ka.
4.删除表格记录警告 ; d, JN
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e) 6o[0sM_];

case ListItemType.Item :

TableCell myTableCell; 3JlC/v#0
myTableCell = e.Item.Cells[14]; 4f{[*6 GX
LinkButton myDeleteButton ; k8InbX[
myDeleteButton = (LinkButton)myTableCell.Controls[0]; [Vrc:%Jk
myDeleteButton.Attributes.Add("onclick","return confirm(’您是否确定要删除这条信息’);"); wq:b j=j
break; M(;y~|e

5.点击表格行链接另一页 l1-4n*fU
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) -vv
{ ".~MmF
//点击表格打开 5z9r S<
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) T!m42EvIvE
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); ^Ei*M0fF
} ~I8v5 H

双击表格连接到另一页 ,X9hl J

} pj!k|F9
W@:^aH
★特别注意:【?id=】 处不能为 【?id =】 tpv?`(DDU
6.表格超连接列传递参数 oS[W*\7'!
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ 2LCc
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> Nbgp_:{
pd=7^"[};
7.表格点击改变颜色 N; rXl8
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) Nhjle@J<
{ C$KaT3I
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; N+*(Y5TU
this.style.color=’buttontext’;this.style.cursor=’default’;"); c_~XL^B@
} =ied}a

8.关于日期格式 V[#6yMU @
II.<S C
日期格式设定 kFS0i%Sr
DataFormatString="{0:yyyy-MM-dd}" j FgZ}Xp
]a78tTi
我觉得应该在itembound事件中 Sv.KI{;v$
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) M#=Y~PU
]MC/t5vC u
9.获取错误信息并到指定页面 6o$Z0mG
xg(<oDn+\
不要使用Response.Redirect,而应该使用Server.Transfer ;
qO@A1Hq
60~v
t04
e.g "\NF
// in global.asax OpYmTep#T\
protected void Application_Error(Object sender, EventArgs e) { .?A'6
if (Server.GetLastError() is HttpUnhandledException) ^/G?QR
Server.Transfer("MyErrorPage.aspx"); lTn;3'
5fU!'ajaN7
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) cL6 6gOEL
} wG_4$kyj
Sq?,C&LsA
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 EJO.'vQ

10.清空Cookie Y3D3.T6Q
Cookie.Expires=[DateTime]; D 5=C^`$2
Response.Cookies("UserName").Expires = 0 |p;4dL
