Hi Inge! Thank you for response :)
I added to my childTable property:
LookupPageId = [pageId]
and to my parentPage on field "Parent No." property:
LookupPageId = [childPageId]
After I click on "Parent No." value i get small box, with related lines (i don't need this at all). I can click "Open full list" to open childPage with full data. The problem is that when the entire page is opened, all the records contained in the childTable appear, not just those with the corresponding Parent No.

How to fix this? Can I set range on 'Parent No.'? In addition, disabling the appearance of this small window would also be useful. I want to show only full childPage with corresponding "Parent No.".
Best Regards!

That should not be nessesary if you have designed the correct relations between your tables.
Maybe you can share more of your code so it is easier to assist you. If you do not want to share your code here then you can send me an e-mail or an message.
