Contoh

Contoh kode berikut mengatur FormattingApplied properti ke untuk true memberi sinyal bahwa pemformatan untuk sel ini selesai.

Keterangan

Saat menangani CellFormatting peristiwa, atur properti ke FormattingAppliedtrue setelah mengatur Value properti jika tidak ada pemformatan nilai lebih lanjut yang diperlukan. FormattingApplied Jika nilai properti adalah false ketika penanganan aktivitas keluar, pemformatan akan diterapkan ke nilai seperti yang ditunjukkan oleh Formatproperti , FormatProvider, NullValue, dan DataSourceNullValue objek yang DataGridViewCellStyle dikembalikan oleh CellStyle properti .
