Keterangan
ButtonType Ketika properti diatur ke ButtonType.Image dan ShowPreviousPageButton properti diatur ke true, gunakan PreviousPageImageUrl properti untuk menentukan URL ke gambar yang ditampilkan untuk tombol halaman sebelumnya. Gambar ini dapat dalam format file apa pun (.jpg, .gif, .bmp, dan sebagainya) yang didukung di browser.
ButtonType Ketika properti diatur ke nilai selain ButtonType.Image, pengaturan PreviousPageImageUrl properti tidak berpengaruh.
Nilai properti ini disimpan dalam viewstate.
