1. 打开新的窗口并传送参数: Yq
Fzbm{\
lC4By,1*
传送参数: Q|1bF!#(1
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") yJL"uleRT
p)jxqg
接收参数: AFFLnLA<L
string a = Request.QueryString("id"); }M7kApb>Y
string b = Request.QueryString("id1"); Sy'>JHx
dJ!o/y6
2.为按钮添加对话框 -Fdi,\e
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); CIDL{i8
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 4eEs_R

3.删除表格选定记录 =z/F=1^<
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; D1n2Z:9
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 2|=_kN8;

5.点击表格行链接另一页 %p9bl ,x
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) c6HU'%v
{ zK 2wLX
//点击表格打开 UW*aSZ/?
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) O0~d6Ba
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); bIArAS9%
} 8w&rj-

双击表格连接到另一页 s=TjM?)

在itemDataBind事件中 //Gvk|O1

string OrderItemID =e.item.cells[1].Text; j''Iai_

★特别注意:【?id=】 处不能为 【?id =】 EaD@clJS
6.表格超连接列传递参数 =%\6}xPEl<
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ EKPTDKut
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ;J(,F:N
+q/h:q.TV
7.表格点击改变颜色 Qu,k
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) jw[BtRW
{ XKX,7
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 4Aew
)
this.style.color=’buttontext’;this.style.cursor=’default’;"); $ rYS
} &=Zg0Q
/>Vx*^u8Hz
写在DataGrid的_ItemDataBound里 HY4E
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) F2$bUY
{
<%D"eD
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; X`n0b<
this.style.color=’buttontext’;this.style.cursor=’default’;"); b0b9#9x
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); s[q4K
} U"+ ry.3`

8.关于日期格式 !><
%\K
r`&|)Hx
日期格式设定 mRH]'dlD7
DataFormatString="{0:yyyy-MM-dd}" WKl'
kqW<e[
我觉得应该在itembound事件中 6b70w @P!
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) huJq#5?

9.获取错误信息并到指定页面 +.]}f}Y
G}#/`]o!K
不要使用Response.Redirect,而应该使用Server.Transfer +MZO%4
X8
)>}#:
e.g cIvYfgIo9
// in global.asax e=l5j"gq
protected void Application_Error(Object sender, EventArgs e) { ~H|LWCU)K8
if (Server.GetLastError() is HttpUnhandledException) AC:s4iacC
Server.Transfer("MyErrorPage.aspx"); RzRvu]]8
p=+*g.,O
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) d?M!acB
} Tn0l|GRuZA
n&m?BuG
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 (}X?v`Y^W

10.清空Cookie / =m9s
Cookie.Expires=[DateTime]; 'e>sHL
Response.Cookies("UserName").Expires = 0 cNo4UZvr
