1. 打开新的窗口并传送参数: ~,ac{%8x

传送参数: ym-212wl
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") Hd4&"oeY

接收参数: [j&>dE
string a = Request.QueryString("id"); %uQ^mK
string b = Request.QueryString("id1"); #B54p@.}
F> ..eK
2.为按钮添加对话框 WWD\EDnS
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); yfYAA*S!z
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") BHa!jw_~o
G3KiU($V
3.删除表格选定记录 W/fM0=!
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; tk ~7>S
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() V<+d o|@F

private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) cy%^P^M

//点击表格打开 ?;!l-Dy

双击表格连接到另一页 /id(atiF^

在itemDataBind事件中 `UGHk*DL)

★特别注意:【?id=】 处不能为 【?id =】 [r<lAS{ .
6.表格超连接列传递参数 hZU@35~BN
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ <Pg4>
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> xOp8[6Ga'

7.表格点击改变颜色 R^{Ow
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 9YwK1[G6/
{ -[^aWNqyJ
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; wRCGfILw
this.style.color=’buttontext’;this.style.cursor=’default’;"); OxZw;yD
} &Vd,{JU
2*ZB[5_V
写在DataGrid的_ItemDataBound里 \J.PrE'(}
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 7&DhEI ^
{ &>XIK8*
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; eZ8~t/8

8.关于日期格式 NnRR"'
)`, Bt
日期格式设定 0hp*(, L
DataFormatString="{0:yyyy-MM-dd}" j|N;&s`
tg_v\n
我觉得应该在itembound事件中 R/VrBiw
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) TyI"fP
}'U"HHv
9.获取错误信息并到指定页面 /J")S?. [u
WPPz/c|j
不要使用Response.Redirect,而应该使用Server.Transfer MdV-;uf
U ]Ek5p
e.g IV]s!
// in global.asax -|"W|K?nq
protected void Application_Error(Object sender, EventArgs e) { +]
s"* 'V$
if (Server.GetLastError() is HttpUnhandledException) XT~!dq5
Server.Transfer("MyErrorPage.aspx"); qv>?xKSm
h&|q>M3
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) qq9fZZb
} @*`9!K%
]@wee 08
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 6`Zx\bPDm
