    It can be done, of course. First, you could control each time a new row is added by DataGridViewhandling the event RowsAddedand then set the cell value of the type DataGridViewCheckBoxColumnlike this:

    private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
    // e.RowIndex proporciona el índice de la fila que se acaba de añadir
    dataGridView1.Rows[e.RowIndex].Cells["NombreDeTuCeldaCheckBox"].Value = true;
}

    But beware, if you DataGridViewhad previous data, you would first save the number of existing records in a variable and check that the new index was greater than that number, or else you would mark all the CheckBoxes.
