1. 打开新的窗口并传送参数: .w `1;o
`/mcjKQ&9y
传送参数: do:3aP'S,
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") /J"U`/
{4
aQK>q. t
接收参数: }I\hOL
string a = Request.QueryString("id"); q!
+?
string b = Request.QueryString("id1"); )NwIEk>Tf
A:3:Cr
2.为按钮添加对话框 /k(KA [bS
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); : _>/Yd7-&
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") EfR3$sp
m};Qng]
3.删除表格选定记录 ?{"_9g9
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
De>'
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Cku&s

4.删除表格记录警告 /OpVr15

5.点击表格行链接另一页 %E95R8SL
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) smpz/1U

//点击表格打开 *TpzX

★特别注意:【?id=】 处不能为 【?id =】 wN [mU
6.表格超连接列传递参数 3/P#2&jt
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ C WJGr:}&
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> \atztC{-L>

7.表格点击改变颜色 {shf\pm!o
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) RbUhLcG5
{ 2s{PE
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; _jV(Gv'
this.style.color=’buttontext’;this.style.cursor=’default’;"); $sDvE~f0n

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; wYtL1D(

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); P q\m8iS,w

8.关于日期格式 V#PT.,Xa.
l'\m'Ioh
日期格式设定 qS[nf>"
DataFormatString="{0:yyyy-MM-dd}" O FlY"OS[
a&`Lfw"
我觉得应该在itembound事件中 eG5xJA^
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 9\R+g5
,HW[l.v
9.获取错误信息并到指定页面 _ Av_jw`m
~,84E [VV
不要使用Response.Redirect,而应该使用Server.Transfer rge/qUr/^
K~\Ocl
e.g H[iR8<rhQ
// in global.asax cfW;gFf
protected void Application_Error(Object sender, EventArgs e) { U#n1N7P|$F
if (Server.GetLastError() is HttpUnhandledException) 2o`L^^
Server.Transfer("MyErrorPage.aspx"); :W1B"T<
ca$K)=cDW
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 0qo:M3
} )L7h:%h#
R-Z)0S'ZR
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 c0:`+>p2

Cookie.Expires=[DateTime]; #;>v,Jo
Response.Cookies("UserName").Expires = 0 "?{=|%mf
