Display Parent and All Child Records when Value from a Child Record is Selected

[MTOnet]

I am having difficulty with a problem that I am trying to solve.  I am trying to display the Parent and all Child records, when a value from one of the child records is selected from a filter, that is seperate from the data.

I have been able to display all child records when the selected value matches the parent record as well as the parent when a child record is selected, but I am having difficulty getting all the child records.

Here is my Data

ID	Parent ID	Type	Assigned
1		Type1	PersonA
2		Type1	PersonB
3		Type1	PersonC
4	1	Type2	PersonB
5	2	Type2	Person A
6	3	Type2	PersonD
7	2	Type3	PersonC
8	1	Type3	PersonB
9	3	Type3	PersonA

Desired Result - If PersonD is selected from the Filter, then display the following

ID	Parent ID	Type	Assigned
3		Type1	PersonC
6	3	Type2	PersonD
9	3	Type3	PersonA

I've tried taking the parent ID of a row and then creating a filtered table to see if the the selected Assigned value exists in that filterd table, but I can't seem to quite get the logic right.  Is there a different way I should approach this.  Thanks for any assistance.

So I solved my issue. and it was such an easy fix.  There was a filter being applied on my data, which resulted in me not getting what I wanted.  Once I added All(Table) to my filter, I got the results i was looking for.  For anybody else looking for this, here is my solution.

RelatedtoAssigned = 
var result = switch(max('Table'[Type]),
    "Type1",if(CONTAINS( Filter(all('Table'),'Table'[ParentID]=max('Table'[Id])),'Table'[Assigned],[SelectionAssignedTo]),1,0),
    "Type2",if(CONTAINS( Filter(all('Table'),'Table'[ParentID]=max('Table'[ParentID])),'Table'[Assigned],[SelectionAssignedTo]),1,0),
    "Type3",if(CONTAINS( Filter(all('Table'),'Table'[ParentID]=max('Table'[ParentID])),'Table'[Assigned],[SelectionAssignedTo]),1,0))
return
    result
    
Where [SelectionAssignedTo] is a measure that gets the value selected in the filter
