1. 打开新的窗口并传送参数: Bl=tYp|a
xf|mlHS+
传送参数: (O0Urm
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") oK 6(HF'&
sz9L8f2
接收参数: NcY608C
string a = Request.QueryString("id"); AT5aDEb^^
string b = Request.QueryString("id1"); &89oO@5
/x3/Ubmz~x
2.为按钮添加对话框 q^6 +!&"
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); eh"3NRrN
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") N!*_La=TuH

3.删除表格选定记录 LM2TZ
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; Bn>8&w/P
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() SNY~9:;]f

4.删除表格记录警告 L~ s3b

private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) >CkjUZu]&

//点击表格打开 h&kZjQ&
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) A19;1#$=
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); vVE7fq3

双击表格连接到另一页 3"{.37Q

★特别注意:【?id=】 处不能为 【?id =】 CXCpqcC
6.表格超连接列传递参数 $t/x;<.H
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ yOvm`9
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> <`0h|m'U

7.表格点击改变颜色 d,by/.2
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) F9*g=
{ 5?Wto4j
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; $u/E\l
this.style.color=’buttontext’;this.style.cursor=’default’;"); [ib P%xb
} C4NTh}6tT
P<fnLQ9
写在DataGrid的_ItemDataBound里 =!Q7}z1QI
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) >*wtbkU
{ hTbI -u7BF
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; y?SyInt
this.style.color=’buttontext’;this.style.cursor=’default’;"); lHV[Ln`\x
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); $fgf

} Iz[@^IUx=

8.关于日期格式 FaBqj1O1
|T{C,"9y
日期格式设定 c`fG1s
DataFormatString="{0:yyyy-MM-dd}" rcGb[=B f
xTGxvGv8
我觉得应该在itembound事件中 2On_'^O
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) "YB**Y
C.kxQ<
9.获取错误信息并到指定页面 s{w[b\rA
ai*f
F
不要使用Response.Redirect,而应该使用Server.Transfer O 1oxZj
<
iZZ (4
e.g }za[E>z
// in global.asax
+D1 d=4
protected void Application_Error(Object sender, EventArgs e) { +1~Z#^{&
if (Server.GetLastError() is HttpUnhandledException) <x\7L2#p
Server.Transfer("MyErrorPage.aspx"); Gy[O)PEEh
&
/4k7X}y
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) V)P&Zw
} <94_@3
r",]Voibd
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 "z<azs
r&Ca"dI
10.清空Cookie ?:Y#Tbi3
Cookie.Expires=[DateTime]; mm5$>
[%U
Response.Cookies("UserName").Expires = 0 H_?o-L?+
E\u#t$
