如何在asp.net中实现listbox item值上下移动?(转)

全部.net为：

 1     < form  id ="myform"  runat ="server" >
 2     < div >
 3             < asp:ObjectDataSource  ID ="ObjectDataSource1"  runat ="server"  OldValuesParameterFormatString ="original_{0}"
 4            SelectMethod ="GetDepartmentsAll"  TypeName ="Cvv.BLL.Bases.DepartmentBLL" > asp:ObjectDataSource >
 5          < table   border ="0"   width ="300" >
 6            < tr >
 7            < td  colspan ="4"  align =center >
 8               流程名称： < asp:TextBox  ID ="tbProcessName"  runat ="server" > asp:TextBox >
 9                          < asp:RequiredFieldValidator  ID ="rfvProcessName"  runat ="server"  ErrorMessage ="请输入"  ControlToValidate ="tbProcessName"  Display ="Dynamic" > * asp:RequiredFieldValidator >
10                          < asp:RegularExpressionValidator  ID ="revProcessName"  runat ="server"  ErrorMessage ="请不要输入单引号和空白"  ControlToValidate ="tbProcessName"  ValidationExpression ="[^'\s]{1,50}"  Display ="Dynamic" > asp:RegularExpressionValidator >                
11                td >
12            tr >          
13            < tr >   
14            < td  width ="40%" > 部门列表 td >   
15            < td   align ="center"  style ="width: 20%" > 操作 td >   
16            < td  style ="width: 40%" > 流程顺序 td >   
17            < td  style ="width: 43px" > 调整 td >   
18            tr >   
19              < tr >
20                  < td  style ="width: 40%" >

23                      asp:ListBox > td >
24                  < td  align ="center"  style ="width: 20%" >
25                      < asp:Button  ID ="Addbtn"  runat ="server"  OnClick ="Addbtn_Click"  Text ="添加"   />< br >< br >

30                  < td  style ="width: 43px" >
31                      < asp:Button  ID ="Upbtn"  runat ="server"  OnClick ="Upbtn_Click"  Text ="上移"   />< br >< br >
32                      < asp:Button  ID ="Downbtn"  runat ="server"  OnClick ="Downbtn_Click"  Text ="下移"   /> td >
33              tr >
34              < tr >
35                  < td  colspan ="4"  align =center >
36                      < asp:Button  ID ="precessadd"  runat ="server"  Text ="确认并提交"  OnClick ="precessadd_Click"   /> td >
37              tr >
38          table >   
39 < input  id ="ListBox1_Click"  type ="hidden"  value ="false"  name ="ListBox1_Click"  runat ="server" >

42option explicit

在.net中使用obojectdata为:

 1     < form  id ="myform"  runat ="server" >
 2     < div >
 3          < table   border ="0"   width ="300" >   
 4              < tr >   
 5              < td   width ="40%" >
 6             < asp:ObjectDataSource  ID ="ObjectDataSource1"  runat ="server"  OldValuesParameterFormatString ="original_{0}"
 7            SelectMethod ="GetDepartmentsAll"  TypeName ="Cvv.BLL.Bases.DepartmentBLL" > asp:ObjectDataSource >
 8             < asp:ListBox  ID ="list1"  runat ="server"  DataSourceID ="ObjectDataSource1"  DataTextField ="DepartmentName"
 9            DataValueField ="DepartmentID"  Height ="411px"  Width ="235px"  ondblclick ="moveOption(document.myform.list1,document.myform.list2)" > asp:ListBox >              
10            td >   
11            < td   width ="20%"   align ="center" >   
12                 < input   type ="button"   value ="添加"   onclick ="moveOption(document.myform.list1,document.myform.list2)" >< br >< br >
13                 < input   type ="button"   value ="删除"   onclick ="moveOption(document.myform.list2,document.myform.list1)" >  
14            td >   
15            < td   width ="40%" >
16            < asp:ListBox  ID ="list2"  runat ="server"  ondblclick ="moveOption(document.myform.list2,document.myform.list1)"  Height ="411px"  Width ="235px" > asp:ListBox >   
17            td >   
18            < td >   
19                < button   onclick ="changepos(list2,-1)"   type ="button" > 上移 button >< br >   
20                < button   onclick ="changepos(list2,1)"   type ="button" > 下移 button >   
21            td >   
22            tr >   
23          table >   
24 < script   language ="JavaScript" >   
25  
61 script >   
62     div >
63     form >
