public bool _blnLeftSideButtons = false;
        public bool LeftSideButtons
        {
            get { return _blnLeftSideButtons; }
            set {
                _blnLeftSideButtons = value;

                if (_blnLeftSideButtons)
                {
                    lstList.Dock = DockStyle.None;
                    flowLayoutPanel1.Dock = DockStyle.Left;
                    lstList.Dock = DockStyle.Fill;
                    Invalidate();
                }
                else
                {
                    lstList.Dock = DockStyle.None;
                    flowLayoutPanel1.Dock = DockStyle.Right;
                    lstList.Dock = DockStyle.Fill;
                    Invalidate();
                }

                }
        }

Add Button Coding

private void btnAdd_Click(object sender, EventArgs e)
        {
            ofD = new OpenFileDialog();
            ofD.Multiselect = true;
            ofD.Filter = "Image Files(*.gif,*.jpg,*.jpeg,*.bmp,*.png,*.wmf)|*.gif;*.jpg;*.jpeg;*.bmp;*.png;*.wmf";

            if (ofD.ShowDialog() == DialogResult.OK)
            {
                if (ofD.FileNames.Length > 0)
                {
                    for (int i = 0; i < ofD.FileNames.Length; i++)
                    {
                        lstList.Items.Add(Path.GetFileName( ofD.FileNames[i].ToString()));
                    }

                if (lstList.SelectedItems.Count == 0) { return; }

                int index = lstList.Items.IndexOf(lstList.SelectedItems[0]);

                if ((index - 1) < 0) { return; }

                object[] obj = new object[lstList.SelectedItems.Count];

                for (int i = 0; i < lstList.SelectedItems.Count; i++)
                {

                lstList.SelectedIndices.Clear();

                for (int j = 0; j < obj.Length; j++)
                {

                    int temp_I = lstList.Items.IndexOf(obj[j]);
                    lstList.Items.RemoveAt(temp_I);
                    lstList.Items.Insert(temp_I - 1, obj[j]);

                    lstList.SelectedIndices.Add(temp_I - 1);

                }
