1. 打开新的窗口并传送参数: @WIcH:_w-

传送参数: _%G)Uz{3
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") # 4E@y<l$

接收参数: HJl$v#]#+
string a = Request.QueryString("id"); (P;z*

string b = Request.QueryString("id1"); e%VJ:Dj

2.为按钮添加对话框 FC.d]XA%/d
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); j{,3!
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") oY@4G)5

3.删除表格选定记录 >Lo 0,b$
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; (g2?&b
iuz
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() K5U=%z

5.点击表格行链接另一页 ?c)PBJ+]
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) V6l*!R
{ Ojj:YLlY>
//点击表格打开 4HlOv%8

e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); ;+]9KIa_Pq

6.表格超连接列传递参数 \&\_[y8U
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ BQVpp,]
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> Mw!?2G[|

7.表格点击改变颜色 EqzS={Olj
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) J{'

{ 5VIpA
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; |D)NPN&

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

8.关于日期格式 v'*
m`C(y$8fU
日期格式设定 V x1C4
DataFormatString="{0:yyyy-MM-dd}" j &)Xi^^
:P`sK&b_
我觉得应该在itembound事件中 RC Fb&,51
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) GL&ri!,
f9H;e(D9]
9.获取错误信息并到指定页面 ]d?`3{h9LD
\{J gjd
不要使用Response.Redirect,而应该使用Server.Transfer vC~];!^
8r / ]Q
e.g xdp!'1n."g
// in global.asax |RwpIe8~
protected void Application_Error(Object sender, EventArgs e) { p,}-8#K[
if (Server.GetLastError() is HttpUnhandledException) ^_3idLE
Server.Transfer("MyErrorPage.aspx"); x!bFbi#!"
9)l-5o:D
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) X>OO4SV
} Acr\2!))
dA>t
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 e:{v.C0ez

10.清空Cookie <uNBsYMuC
Cookie.Expires=[DateTime]; 4xhV

Response.Cookies("UserName").Expires = 0 )hj77~{+
