AutomationProperty

Contoh

Dalam contoh berikut, elemen akar diteruskan ke fungsi yang mengembalikan kumpulan AutomationElement objek yang merupakan keturunan akar dan memenuhi serangkaian kondisi properti. Contoh ini mengambil AutomationElements yang mendukung TablePattern dan di mana RowOrColumnMajorProperty adalah Indeterminate atau ColumnMajor.
