Try following..

private void btnMove_Click(object sender, EventArgs e)
    {
        string strValue = (string)listBox1.SelectedItem; //Get Selected Item.
        int nSelected   = listBox1.SelectedIndex;  //Get Selected Item Index.

        //Check if selected item is last index (count - 1) position.
        if ((nSelected == listBox1.Items.Count - 1) &&
             (listBox1.Items.Count > 1) )
        {

            listBox1.SetSelected( (nSelected - 1) , true);
        }

        //else item count is greater than 1.
        else if (listBox1.Items.Count > 1)
        {
            listBox1.SetSelected( (nSelected + 1) , true);
        }

        //Remove Selected Item.
        if (nSelected >= 0)
        {
            listBox1.Items.RemoveAt(nSelected);

            listBox2.Items.Add(strValue);
            listBox2.Update();
        }
    }
