Listbox selections

Hi, I have this listbox1 populated by a database and next to it another empty one (listbox2). Between the two, 2 buttons "-->" & "<--". You guessed it I need those buttons to add and remove items from listbox1 to listbox2. One they have been removed from listbox1, I do not want those values to still be in it, it's really to move items between the two listboxes. What would be code to achieve this ?
Thanks

Try this code.

Hope it's clear enough for u.

protected void btnAdd_Click(object sender, EventArgs e)
    {
        for (int i = lstFrom.Items.Count - 1; i >= 0; i--)
        {
            if (lstFrom.Items[i].Selected)
            {
                if (lstTo.Items.FindByValue(lstFrom.Items[i].Value) != null)
                {
                    continue;
                }
                else
                {
                    lstTo.Items.Add(lstFrom.Items[i]);
                    lstFrom.Items.Remove(lstFrom.Items[i]);
                }
            }
        }
 
    }
        
 
   
    protected void btnRemove_Click(object sender, EventArgs e)
    {
        try
        {
            for (int i = lstTo.Items.Count - 1; i >= 0; i--)
            {
                if (lstTo.Items[i].Selected)
                {
                    lstFrom.Items.Add(lstTo.Items[i]);
                    lstTo.Items.Remove(lstTo.Items[i]);
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

2 things if I may, if you do a batch add, it adds the items but in reverse order ie. I select 1,2,3,4 but it adds in this order; 4,3,2,1. Also, when I remove an item from the 2nd listbox, how can I make it so that re-appears where it was before ? Thanks
