1. 打开新的窗口并传送参数: &yH#s

传送参数: 0yof u
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") i8V0Ty4~N

接收参数: CKARg8o
string a = Request.QueryString("id"); 6i@ub%qq
string b = Request.QueryString("id1"); 4 9w=kzo

2.为按钮添加对话框 -oBI+v&
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); AfWl6a?T8:
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") rFag@Z"["

3.删除表格选定记录 K, (65>86;
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 993d/z|DX
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Y4~vC[$x'
3\!F\tqD \
4.删除表格记录警告 oo'w-\2]p

5.点击表格行链接另一页 Z*bC#s?
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) me. /o(!?
{ 2,AaP*,
//点击表格打开 D3?N<9g
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) Qyj(L[K J
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); .w'vD/q;
} R`He^
&tBA^igXK
双击表格连接到另一页 R<&FhT]
$Xt;A&l2?
在itemDataBind事件中 A^pW]r=Xtk
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) W(k:Pl#
{ k/#M<z
string OrderItemID =e.item.cells[1].Text; aW`dFitpM
... nYov>x]
e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’"); P0#`anUr1
} ;QidDi_s>
IxP^i{/1?
双击表格打开新一页 v' 0!= r
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) :VFTVmr
{ b?k4InXh
string OrderItemID =e.item.cells[1].Text; #{>uC&jD
... I<`V_
e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)"); px
[~=$F
} )VY10R)$
}N| \
★特别注意:【?id=】 处不能为 【?id =】 5Bd(>'ig_
6.表格超连接列传递参数 WD;)VsP
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ R92R}=G!
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> K`gc 4:A
l:z};
7.表格点击改变颜色 FQ## 397
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) U?EG6t
{ j)Lo'&Y~=
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ;@!;1KDy
this.style.color=’buttontext’;this.style.cursor=’default’;"); VKf6|ae
} BvI 0v:
CXa Ld7nMX
写在DataGrid的_ItemDataBound里 Oo/8Y
E@
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) "3ug}k
{ =AzOnXW:S
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; j]4,6`b\
this.style.color=’buttontext’;this.style.cursor=’default’;"); S~|tfJpL
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); D2?S,9+E_
} iPkT*Cl8

t[j9R#02?
8.关于日期格式 2$DSBQEx
5*XH6g F
日期格式设定 _Ff".t<"
DataFormatString="{0:yyyy-MM-dd}" 7?"9J`*
]0YDb~UB
我觉得应该在itembound事件中 9/Wn!Ld
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) hOn
h{H]xe[Q
9.获取错误信息并到指定页面 5C65v:Q`N
@|'Z@>!/pV
不要使用Response.Redirect,而应该使用Server.Transfer wNR=?Z~
/gX%ABmS
e.g 'F<Sf:?.p
// in global.asax %\l0-RA@<
protected void Application_Error(Object sender, EventArgs e) { &&*wmnWCS{
if (Server.GetLastError() is HttpUnhandledException) [[$Mh_MD
Server.Transfer("MyErrorPage.aspx"); Y)v%
Hq-v@@0 *
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) i2U/RXu
} E]?2!)mgce
d~,n_E$q;
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 1V\1]J/

10.清空Cookie klo^K9!
Cookie.Expires=[DateTime]; S}O5l}E
Response.Cookies("UserName").Expires = 0 0O^U{#*$I
