1. 打开新的窗口并传送参数: vnZC,J `

传送参数: `&c kZiq
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") .5ha}=z
.jWC$SVR
接收参数: zue~ce73J
string a = Request.QueryString("id"); ^ sLdAC
string b = Request.QueryString("id1"); Cd}<a?m,

2.为按钮添加对话框 )

Button1.Attributes.Add("onclick","return confirm(’确认?’)"); nk's_a*Z
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") sN01rtB(UT

3.删除表格选定记录 ou{2@"
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; %^1V4
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() >jc [nk

4.删除表格记录警告 aE$[52

5.点击表格行链接另一页 =wV<hg)C

6.表格超连接列传递参数 ;)z:fToh
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ bSi%2Onj
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> VSI9U3t3w

7.表格点击改变颜色 h#

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) g63(E,;;J
{ tOd&!HYL
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; -4IE]'##
this.style.color=’buttontext’;this.style.cursor=’default’;"); +RM SA^
} +YKi,
;LPfXpR
写在DataGrid的_ItemDataBound里 G3vxjD<DMW
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) CMG&7(MR
{ UapC"XYJ
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; aU "8{

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); JWhdMU

8.关于日期格式 gpvYb7Of0
kY|utoAP
日期格式设定 H.|#c^I
DataFormatString="{0:yyyy-MM-dd}" (Ag16
FF(#]vz '
我觉得应该在itembound事件中 `O!X((
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /hH
lH x^D;m6
9.获取错误信息并到指定页面 RYQR(v
SpLzm A
不要使用Response.Redirect,而应该使用Server.Transfer rv^@, 8vq
n&;85IF1
e.g TA`1U;c{n
// in global.asax ~"&|W'he[
protected void Application_Error(Object sender, EventArgs e) { vkx7paY_
if (Server.GetLastError() is HttpUnhandledException) JHM9
Server.Transfer("MyErrorPage.aspx"); 'qb E=
t~EPn.
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ]7F=u!/`<C
} r4XK{KHn
p;59?
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 y^,1a[U.

10.清空Cookie ^T;*M_
Cookie.Expires=[DateTime]; :bu/^mW[
Response.Cookies("UserName").Expires = 0 V6&!9b
