Validation Rule Groups

xAvailx posted on Wednesday, October 21, 2009

Is there a way to specify a set of validations to be validated together?

The scenario I have is I have about 8 validation rules that need to be triggered based on the state of an object. I would like to do something like

CheckRules.Validate("MyGroup") and it would validate only those 8 rules.

You should probably use ValidationRules.AddDependantProperty to tie different properties's validation together. You could also just call ValidationRules.CheckRules() to run all the rules in your class.

Thanks Sergey, I guess the issue I saw with using a dependent property is the state that triggers these changes come from the parent class.

Is there a way to create a dependent property with no related object property? I think that would solve my issue.

My question is related to this post:

Hi,

I agreee with Sergey that you should look at AddDependentProperty and I 'd prefer to define these as DependentProperties as depedent between properties in your BO.

However - a DependentProperty can also be what you described as a Group that does not have to be an actual implemented property in the BusinessObject.

Ex:
ValidationRules.AddDependentProperty("property1", "group1", true);
ValidationRules.AddDependentProperty("property2", "group1", true);
ValidationRules.AddDependentProperty("property3", "group1", true);

And you could then call:
ValidationRules.CheckRules("group1");

I think this is what I am looking for. See my reply to Sergey regarding further explanation of my scenario. I will give this a shot. Thx!
