Adding more values by choose in the list

Question

Hi all!
Normally with TextBox control, when I choose an item from the list, the Text property value assume the value of the item choosed.
How can I modify this behaviour by adding the value of the item choosed to the existing value (if exist)?
So I would choose many items and see they in the TextBox.
Can I do this?

Thanks and sorry for my english!
Enrico.

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
