Changing the SelectedIndex will change which item is selected, it will not move the selected item up or down in the list. Here's some code to show you how to do that:

        private void btnUp_Click(object sender, EventArgs e) {
            int index = clbItems.SelectedIndex;
            if(index > 0) {
                MoveItem(-1);
            }
        }

        private void btnDown_Click(object sender, EventArgs e) {
            int index = clbItems.SelectedIndex;
            if(index < clbItems.Items.Count - 1) {
                MoveItem(1);
            }
        }

        private void MoveItem(int step) {
            int index = clbItems.SelectedIndex;
            object item = clbItems.SelectedItem;
            // Checked state is lost when you remove and re-insert the item
            bool isChecked = clbItems.GetItemChecked(index);
            clbItems.Items.Remove(item);
            clbItems.Items.Insert(index + step, item);
            clbItems.SetItemChecked(index + step, isChecked);
        }
