Keterangan

Peristiwa ServerClick dimunculkan saat HtmlButton kontrol diklik. Peristiwa server ini menyebabkan perjalanan pulang pergi terjadi dari klien ke server dan kembali. Ini sengaja berbeda dari peristiwa sisi OnClick klien. Jika ada konflik antara kode yang dijalankan dengan peristiwa dan kode yang ServerClick dijalankan oleh peristiwa sisi OnClick klien, instruksi peristiwa sisi server akan mengambil alih kode sisi klien.
