Solution 1

When you select a List Item click on Move Down
That time get the Current Index of the Selected List Item
Then remove the item from the Selected Index
And add the same Item object by Insert with Previous Selected Index + 1

For move up, subtract it by 1 i.e. previous selected index - 1

IIRC, ListView and ListBox behave similarly in this respect.

private void btnUp_Click(object sender, EventArgs e)
{
    this.checkedListBoxAttribute.ItemCheck -= checkedListBoxAttribute_ItemCheck;
    this.checkedListBoxAttribute.SelectedIndexChanged -= checkedListBoxAttribute_SelectedIndexChanged;
    string item = checkedListBoxAttribute.SelectedItem.ToString();
    int selectIndex = checkedListBoxAttribute.SelectedIndex;
    bool state = checkedListBoxAttribute.GetItemChecked(selectIndex);
    checkedListBoxAttribute.Items.RemoveAt(checkedListBoxAttribute.SelectedIndex);
    checkedListBoxAttribute.Items.Insert(selectIndex - 1, item);
    checkedListBoxAttribute.SetItemChecked(selectIndex - 1, state);
    this.checkedListBoxAttribute.ItemCheck +=checkedListBoxAttribute_ItemCheck;
    this.checkedListBoxAttribute.SelectedIndexChanged+=checkedListBoxAttribute_SelectedIndexChanged;
    checkedListBoxAttribute.SelectedIndex = selectIndex - 1;
}
