    ' Create a new DataRow.
    row = table.NewRow()
    ' Detached row.

Comentarios

Al invocar AcceptChangesa EndEdit , se llama implícitamente al método para finalizar cualquier edición.When invoking AcceptChanges, the EndEdit method is implicitly called to end any edits. Si se RowState ha agregado o modificado el de la fila RowState , se convierte en inalterado.If the RowState of the row was Added or Modified, the RowState becomes Unchanged. RowState Si se eliminó, se quita la fila.If the RowState was Deleted, the row is removed.

Vea el método BeginEdit para más información.See the BeginEdit method for more information.

La DataTable clase también tiene un AcceptChanges método que afecta a los cambios realizados en la tabla completa.The DataTable class also has an AcceptChanges method which affects changes made to the whole table. Para obtener más información y un ejemplo de código que muestre cómo aceptar y rechazar cambios en filas de datos individuales, vea AcceptChanges y RejectChanges.For more information and a code example that demonstrates how to accept and reject changes to individual data rows, see AcceptChanges and RejectChanges.
