1. 打开新的窗口并传送参数: 7hc(]8eP

传送参数: ;Mc}If*
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") = 2k+/0ZbP
;4 &~i
接收参数: +1Uw <~
string a = Request.QueryString("id"); >wn&+%i&
string b = Request.QueryString("id1"); &&JMw6

2.为按钮添加对话框 `U1"WcN
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); ;rFa I^
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") ~ M"[FYw[

3.删除表格选定记录 H/b(dbs
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; I|.B-$gH
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() %w@(V([(c

5.点击表格行链接另一页 rsP1?Hxq
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 0uZH H
{ OaEOk57%de
//点击表格打开 EZ$m4:{e
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) Tx!mW-Lt
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); rod{77

双击表格连接到另一页 V8c&2rNa

★特别注意:【?id=】 处不能为 【?id =】 ^hLAMaR
6.表格超连接列传递参数 )p 2kx
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ #pLd';
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ;j S~0R
wU+-;C5e
7.表格点击改变颜色 Bh<)e5lP:
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) p"3_u;cN
{ BlMc<k
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; QF
Vy2 q
this.style.color=’buttontext’;this.style.cursor=’default’;"); 6_rS!X
} &E0P`F,GQA
qE!.C}L+
写在DataGrid的_ItemDataBound里 +O2T%
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) Ar,B7-F!
{ .gzNdSE
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; zq _*)V
this.style.color=’buttontext’;this.style.cursor=’default’;"); DavpjwSn
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); >+LFu?y
} ^1nQDd*

8.关于日期格式 $GB/}$fd&
rzsAnLxo
日期格式设定 vu Vcv
DataFormatString="{0:yyyy-MM-dd}" PS7ta?V
QC
2M1}`H\
我觉得应该在itembound事件中 C5"=%v[gQv
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) kLtm_
Rf9;jwU
9.获取错误信息并到指定页面 o-H\vtOjE
\jH^OXxb
不要使用Response.Redirect,而应该使用Server.Transfer AXFQd@#
qp;eBa
e.g P+K< /i
// in global.asax MROe"Xj
protected void Application_Error(Object sender, EventArgs e) { bh
V.uBH
if (Server.GetLastError() is HttpUnhandledException) 41dB4Td5t
Server.Transfer("MyErrorPage.aspx"); 1g<jr.
Jvac|rN
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) uI lm!*0
} yUd>EnQna
Pr|BhX
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 O1xK\ogv

10.清空Cookie 7\.{O$Q
Cookie.Expires=[DateTime]; zp.-=)D4e
Response.Cookies("UserName").Expires = 0 ZMa@/\pf1
