1. 打开新的窗口并传送参数: ]Jz=.F sO

接收参数: n l5+#e*\
string a = Request.QueryString("id"); %\it4 r3
string b = Request.QueryString("id1"); $I5|rB/4?
&Hw:65O
2.为按钮添加对话框 ^aaj=p:cV
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); *42KLns
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") `_ ^I 2

3.删除表格选定记录 @#wG)TA
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; y95
#t
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() eHx {[J?

5.点击表格行链接另一页 S?DMeZ{:
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 89[/UxM)

6.表格超连接列传递参数 Mt4`~`6
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ *{fZA;<R
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> }Ej^"T:H_;

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 7vqE@;:dt
{ yrzyus
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 'mU\X!-

this.style.color=’buttontext’;this.style.cursor=’default’;"); =+e;BYD#!
} 9dg+@FS}=

8.关于日期格式 Dk~
JH9#
`C:J {`
日期格式设定 )q7!CG'oY
DataFormatString="{0:yyyy-MM-dd}" ZYl*-i&~?
QswFISch
我觉得应该在itembound事件中 !&8B8jHqA
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) !;PKx]/&
0@!-+}i
9.获取错误信息并到指定页面 =rNI&K_<
LZPLz@=&]
不要使用Response.Redirect,而应该使用Server.Transfer c5Hm94,p
w="
e.g K?wo AuY
// in global.asax 6K.0dhl>`B
protected void Application_Error(Object sender, EventArgs e) { H|N,nkhH}
if (Server.GetLastError() is HttpUnhandledException) ~:A=o?V2
Server.Transfer("MyErrorPage.aspx"); ~RM_c
jW|M)[KJN
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 9&4z4@on
} %tz foiJ%P
orF8%
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 |>p?Cm
