Checks the business rules on the current row returned error.

private void TbCadastroBO_CheckRulesOnCurrentRow(CheckRulesEventArgs e)
{
    if (this.Foto.Width > 110 || this.Foto.Height > 150)
        this.AddBrokenRule(TbCadastroBOFieldNames.Foto, "Foto com dimensão inválida");
    if (this.Foto.HorizontalResolution > 210 || this.Foto.HorizontalResolution < 80
        || this.Foto.VerticalResolution > 210 || this.Foto.VerticalResolution < 80)
        this.AddBrokenRule(TbCadastroBOFieldNames.Foto, "Foto com resolução inválida");
}

Please. To cancel this occurrence, therefore I already identified the code that was causing the error.
Invalid verify business rules in BusinessRulesChecked was returning error.

private void tbCadastroBO1_BusinessRulesChecked(MicroFour.StrataFrame.Business.BusinessRulesCheckedEventArgs e)
{
    ClearErrorProvider();
    //-- Verify Business Rules
    if (!tbCadastroBO1.CheckRulesOnRow())
    {
        foreach (BrokenRule loRule in tbCadastroBO1.BrokenRules.ToArray())
        {
            if (loRule.FieldName.EndsWith("Foto", StringComparison.OrdinalIgnoreCase))
                SetErrorProvider(picFoto, loRule.Description);
        }
    }
}

This is OK.
private void tbCadastroBO1_BusinessRulesChecked(MicroFour.StrataFrame.Business.BusinessRulesCheckedEventArgs e)
{
    foreach (BrokenRule loRule in tbCadastroBO1.BrokenRules.ToArray())
    {
        if (loRule.FieldName.EndsWith("Foto", StringComparison.OrdinalIgnoreCase))
            SetErrorProvider(picFoto, loRule.Description);
    }
}
