Adding more values by choose in the list

Hi Enrico,

We are not clear about your question.But instead of textbox use listbox.



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
   
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            listBox1.Items.Add("Raj");
            listBox1.Items.Add("Raj");
            listBox1.Items.Add("Raju");
            listBox1.Items.Add("Rahul");
            listBox1.Items.Add("Harry");
            listBox1.Items.Add("Ben");
            listBox1.Items.Add("Ian");

        }

     
        private void btn_right_Click(object sender, EventArgs e)
        {
            if (listBox2.Items.Contains(listBox1.SelectedItem) == true)
            {
                MessageBox.Show(listBox1.SelectedItem + ":::Item Exits");
            }
            else
            {
                listBox2.Items.Add(listBox1.SelectedItem);
                MessageBox.Show(listBox1.SelectedItem + ":::Item Added");
                int i = 0;
                i = listBox1.SelectedIndex;
                listBox1.Items.RemoveAt(i);
               
            }
        }

        private void btnleft_Click(object sender, EventArgs e)
        {
            listBox1.Items.Add(listBox2.SelectedItem);
            int i = 0;
            i = listBox2.SelectedIndex;
            listBox2.Items.RemoveAt(i);
        }
    }
}



Thanks
