Expression to group components?

ndamgaard — Thu, 06 Jan 2022 09:39:34 GMT

In Ilogic rules, is it possible to create and expression that groups a selection of components, so that all these components can be referenced with one expression (e.g. Component.Isactive(group)=True or False)?

To give an idea of what I am trying t

--------
component_group=List("Assembly1", "Assembly2", "Assembly3", "Assembly4",..., "Assembly99")


If statement1=True Then
	Component.IsActive(component_group)=True

If statement1=False Then
        Component.IsActive(component_group)=False

EndIf
--------
I hope it is apparent what I am trying to achieve. Otherwise, let me know.

You can use this idea, but you need to add a loop in you code to suppress each component. Here's a small sample:

Dim MyGroup = New String(){"P144-00030:1", "P144-00029:2","P133-00210:1"}

For Each oVal In MyGroup
		Component.IsActive(oVal) = False
Next

Thanks for the response.

It works!

Hello Theo,

A follow up question: Can I reference MyGroup in another rule?

I wish to keep my categories in its own rule, if possible.

In your main rule you can create a SharedVariable. In other rules you can use this sharedVariable.

so rule1:

Dim MyGroup = New String(){"P144-00030:1", "P144-00029:2","P133-00210:1"}

SharedVariable("MyGroup") = MyGroup

Rule2:

For Each oVal In SharedVariable("MyGroup")
		Component.IsActive(oVal) = False
Next
