Comentarios

Cuando la AutoGenerateColumns propiedad se establece trueen , cada columna establece automáticamente su DataPropertyName propiedad en el nombre de una propiedad o columna de base de datos en el origen de datos especificado por la DataSource propiedad . Este enlace también se puede realizar manualmente, lo que resulta útil cuando desea mostrar solo un subconjunto de las propiedades o columnas de base de datos disponibles en el origen de datos. En tales casos, establezca la AutoGenerateColumns propiedad falseen y, a continuación, agregue manualmente cada DataGridViewColumn, estableciendo el valor de cada DataPropertyName propiedad en las propiedades o columnas de base de datos del origen de datos que desea mostrar.
