One question here what value should display in textbox. In your example DS003 is present in both ListBox and DS001 is present in both listbox. And DS003, DS001 are displaying in textbox. What logic you used here - please describe it.

if (item != null)
{
   //found
   ListBox2.Items.Add(item);
}

or

ListItem item = new ListItem(txtUser.Text);

// Checking if listeitem is exist then add to Listbox2
if (ListBox1.Items.Contains(item) ){
   ListBox2.Items.Add(item);
