Keterangan

Nilai ImageIndex mereferensikan nilai terindeks gambar dalam yang ImageList ditetapkan ke kontrol induk ToolBar .

ImageKey dan ImageIndex saling eksklusif, yang berarti jika satu diatur, yang lain diatur ke nilai yang tidak valid dan diabaikan. Jika Anda mengatur ImageKey properti , ImageIndex properti secara otomatis diatur ke -1. Atau, jika Anda mengatur ImageIndex properti , ImageKey secara otomatis diatur ke string kosong ("").
