Items moving from one list to another

Hi Jagjit,

Here is your solution.

For DropDownList below code

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>





   


   

   

   
   
  
               onclick="btn_leftall_Click"  />
               onclick="btn_rightall_Click"  />
  
   

   

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            DropDownList1.Items.Add("Raj");
            DropDownList1.Items.Add("Ravi");
            DropDownList1.Items.Add("Rahul");
            DropDownList1.Items.Add("Raju");
            DropDownList1.Items.Add("Rohit");
            DropDownList1.Items.Add("Rajesh");
        }
    }
   
    protected void btn_left_Click(object sender, EventArgs e)
    {
        DropDownList1.Items.Add(DropDownList2.SelectedItem.Text);
        int i = 0;
        i = DropDownList2.SelectedIndex;
        DropDownList2.Items.RemoveAt(i);
    }
    protected void btn_right_Click(object sender, EventArgs e)
    {
        DropDownList2.Items.Add(DropDownList1.SelectedItem.Text);
        int i = 0;
        i = DropDownList1.SelectedIndex;
        DropDownList1.Items.RemoveAt(i);
    }
    protected void btn_leftall_Click(object sender, EventArgs e)
    {
        int j = 0;
        for (j = 0; j <= DropDownList2.Items.Count - 1; j++)
        {
            DropDownList1.Items.Add(DropDownList2.Items[j]);
        }
        DropDownList2.Items.Clear();
    }
    protected void btn_rightall_Click(object sender, EventArgs e)
    {
        int j = 0;
        for (j = 0; j <= DropDownList1.Items.Count - 1; j++)
        {
            DropDownList2.Items.Add(DropDownList1.Items[j]);
        }
        DropDownList1.Items.Clear();
    }
}


For Listbox below code

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>





 


 

 

 
 
 
 
 
 
 

 

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack)
  {
  ListBox1.Items.Add("Raj");
  ListBox1.Items.Add("Ravi");
  ListBox1.Items.Add("Rahul");
  ListBox1.Items.Add("Raju");
  ListBox1.Items.Add("Rohit");
  ListBox1.Items.Add("Rajesh");
  }

  }
  protected void Button1_Click(object sender, EventArgs e)
  {
  ListBox1.Items.Add(ListBox2.SelectedItem.Text);
  int i = 0;
  i = ListBox2.SelectedIndex;
  ListBox2.Items.RemoveAt(i);

  }
  protected void Button2_Click(object sender, EventArgs e)
  {
  ListBox2.Items.Add(ListBox1.SelectedItem.Text);
  int i = 0;
  i = ListBox1.SelectedIndex;
  ListBox1.Items.RemoveAt(i);

  }
  protected void Button3_Click(object sender, EventArgs e)
  {
  int j = 0;
  for (j = 0; j <= ListBox2.Items.Count - 1; j++)
  {
  ListBox1.Items.Add(ListBox2.Items[j]);
  }
  ListBox2.Items.Clear();

  }
  protected void Button4_Click(object sender, EventArgs e)
  {
  int j = 0;
  for (j = 0; j <= ListBox1.Items.Count - 1; j++)
  {
  ListBox2.Items.Add(ListBox1.Items[j]);
  }
  ListBox1.Items.Clear();

  }
}
