. El valor predeterminado es false
.
Ejemplos
En el ejemplo de código siguiente se establece la FormattingApplied propiedad en para true
indicar que finaliza el formato de esta celda.

// value.

Comentarios
Al controlar el CellFormatting evento, establezca la FormattingApplied propiedad true
en después de establecer la Value propiedad si no se requiere ningún formato de valor adicional. Si el valor de la FormattingApplied propiedad es false
cuando sale el controlador de eventos, el formato se aplicará al valor indicado por las Formatpropiedades , FormatProvider, NullValuey DataSourceNullValue del DataGridViewCellStyle objeto devuelto por la CellStyle propiedad .
