Keterangan

MergeWith Gunakan metode untuk menggabungkan properti gaya objek yang ditentukan Style dengan properti TreeNodeStyle gaya objek tempat metode ini dipanggil.

Catatan

Metode MergeWith ini menggabungkan properti gaya dengan mengatur setiap properti yang tidak diatur dalam objek saat ini TreeNodeStyle dengan nilai yang sesuai dalam objek yang ditentukan Style . Hanya properti yang belum disetel yang diperbarui. Jika properti dalam objek yang ditentukan Style tidak diatur, properti terkait dalam objek saat ini TreeNodeStyle tidak berubah.
