interation between 2 visual to filter data

Hi Anonymous Could you try adding a selection for child also 

Control_child_table =
VAR parent_id = SELECTEDVALUE(Parent[id]) -- Parent Table
VAR child_id = SELECTEDVALUE(Child[id]) --  Child Table
RETURN
IF(
    NOT(ISBLANK(parent_id)) && (child_id = parent_id || ISBLANK(child_id)), 
    1, 
    0
)

I tried still when i click on Child visual data it goes blank. i also added screenshot of changed measure and show Interaction of child with parent visual. on child i applied that dax measure.

Could you please provide me the sample data in csv or xlsx 

It won't let me attach file so i added sample data in below tables. Thanks

Parent Table

ID      Name

Child Table

ID       Name

Hi Anonymous 

Control_child_table = 
VAR parent_id = MAXX(ALLSELECTED('Parent Table'), 'Parent Table'[ID]) -- Get Parent ID, ignoring Child selection
VAR child_id = MAX('Child Table'[ID]) -- Current Child ID
RETURN
IF(
    NOT(ISBLANK(parent_id)) &&
    child_id = parent_id,
    1,
    0
)

Hi Akash, i updated with dax you mentioned above now its showing  a value (5, qr) even when no row selected in parent view. I think main concern is when i cick id 1 on parent it filter in 2nd view but as soon as i click inside data in child visual it reset back to(5,qr). we need to preserve selected values based on parent view.
