Keterangan

Properti Position harus diatur setelah ListViewItem dan yang berisi ListView dibangun. Mengubah Position properti saat penampung ListView berada di dalam Details atau List tampilan tidak akan berpengaruh pada posisi item. Selain itu Position , properti akan secara otomatis berubah ketika View properti yang berisi ListView diubah dari SmallIcon, , LargeIconatau Tile lihat ke List atau Details. ListView Saat berada dalam SmallIcontampilan , , LargeIconatau Tile , mengatur Position properti untuk item akan menyebabkan item lain yang terkandung dalam ListView diatur ulang.
