1. 打开新的窗口并传送参数: @h(!<Ux_
WW6yFriuW
传送参数: H%C\Uz"o
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") yQwVQUW8B
V{GXc:=
接收参数: rhoeZ
string a = Request.QueryString("id"); HamEIL-l.
string b = Request.QueryString("id1"); 4#h?Wga
;
8E;
2.为按钮添加对话框 G_+Ph^
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); :'Xr/| s
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") S.hC$0vrj

3.删除表格选定记录 e?=elN
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; n;qz^HXEJ
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() L=m:/qQL

5.点击表格行链接另一页 ?[|hGR2L
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) `#U ]iwW!
{ 4,zvFH*AH
//点击表格打开 ^9'$Oa,*
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) avBu a6i'
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); C#$6O8O

双击表格连接到另一页 gLx/w\l6

★特别注意:【?id=】 处不能为 【?id =】 <N-=fad]
6.表格超连接列传递参数 QXB|!'
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ gWi{\x8dt

7.表格点击改变颜色 zv@bI~3~
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) K9*IA@xL
{ u{P~zyx
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; #!L%J<MX
this.style.color=’buttontext’;this.style.cursor=’default’;"); fa yKM
} [G=:?J,P
U$%|0@`~
写在DataGrid的_ItemDataBound里 AI~9m-,mE

{ on_H6Y@B52
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; Wz5=(<{S

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); j9>TTgy@

8.关于日期格式 '{CWanTPi
B#:E?a;{
日期格式设定 L&'l3|
DataFormatString="{0:yyyy-MM-dd}" ]K*GSU
}biCQ*{'
我觉得应该在itembound事件中 MISE C[/
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) @sdS0pC
19) !$Hl
9.获取错误信息并到指定页面 R|-j]Ne
V pH|R
不要使用Response.Redirect,而应该使用Server.Transfer dxntGH< O
EZ `}*Yrd
e.g mV%h[~-
// in global.asax ]Ly8s#<g]N
protected void Application_Error(Object sender, EventArgs e) { D Kq-C%
if (Server.GetLastError() is HttpUnhandledException) N"K\ick6J
Server.Transfer("MyErrorPage.aspx"); QheDF7'z
p&uCp7]U
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) a-:pJE.'p
} La]4/=a

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 q}e]*]dJZ
