Business rules Execution

[Chicagoan2016]

I think I have asked a similar question before : )

Today I am working on a simple object with seven properties. All of them are required.
When all the properties are present, a final business rule needs to run that does calculations based on all the properties.
However, when I test the business object with, say, three properties missing, it still tries to run the final 'calculation' business rule.

Kind Regards

You can create a rule with a lower priority than the calculation rule that checks if the object is valid and stops processing if not.

  public class StopIfNotValid : PropertyRule
{
    public StopIfNotValid(IPropertyInfo primaryProperty) : base(primaryProperty)
    {
    }

    protected override void Execute(IRuleContext context)
    {
        if (!((BusinessBase)context.Target).IsValid)
        {
            context.AddSuccessResult(true);
        }
    }
}

Thank you @danielmartind .
Since my 'calculation' rule requires multiple properties. I slightly modified your rule so that no business rules would be run for the 'whole' object in cases where the object is invalid but no luck : (
Although the 'StopIfNotValid' is getting called but it's causing short circuiting for the 'whole' object.

Here is my version, I just removed the primary property

  public class StopIfNotValid : PropertyRule
{
    public StopIfNotValid() : base()
    {
    }

    protected override void Execute(IRuleContext context)
    {
        if (!((BusinessBase)context.Target).IsValid)
        {
            context.AddSuccessResult(true);
        }
    }
}

Not sure of the details of your scenario.
I have 3 numbers and a total property with a rule that calulates the property.

        BusinessRules.AddRule(new MinValue<int>(Num1Property, 5));
        BusinessRules.AddRule(new MinValue<int>(Num2Property, 10));
        BusinessRules.AddRule(new MinValue<int>(Num3Property, 15));

        BusinessRules.AddRule(new StopIfNotValid(TotalProperty));
        BusinessRules.AddRule(new CalcSum(TotalProperty, Num1Property, Num2Property, Num3Property) { Priority = 10 });

CalcSum only works when the three number properties are valid

@danielmartind I wonder if you try to set Num1 or Num2 from 'UI', will it trigger CalcSum?
In my case invalid dependent properties like Num1, Num2 are triggering the CalcSum

I've just set this up in a console app. Total doesn't change until all number properties are valid. You can see here
