How can I write a C# winforms code like this?

CheckedListBox items don't have 'Tag' and 'ValueMember' properties.

I know there are many alternatives to this. But I need to work it this way.

private void LoadPermissionsToCheckedListBox()
        {
            Role selctedRole = (Role)comboBox1.SelectedItem;

            int i = 0;
            foreach (Permission p in selctedRole.PermissionItems)
            {
                checkedListBox1.Items.Add(p);
                checkedListBox1.Items[i].Tag = p;
            }

            checkedListBox1.DisplayMember = "PermissionKey";
            checkedListBox1.ValueMember = "PermissionID";
        }
