Hi,

I am trying to add the new Power Apps grid control in a model-driven app for a custom table (type Standard), and trying to add child items from another custom table (type Activity), but in run time the related child records do not show up...

I tested for custom tables where they are both (type Standard) and it worked just fine!

I am not sure if there is anything else needed from my side, but appreciate if someone could confirm this behavior.

regards,

Mohammad

Which field did you choose in Child Items Parent Id parameter of the grid control? As far as I understand, you cannot choose the regardingobjectid (Regarding) column from your activity table because it only allows Lookup.Simple columns and not Lookup.Regarding.
I created a custom lookup column from the Activity table to the Standard table (lzw_test and not RegardingObjectId). Then, it seems to show the activity table as the child item as in the screenshot below.

@malkhawaja and @donalmc

Have you raised a ticket with Microsoft Support and screen share about it?

Hi @LinnZawWin - not yet - the feature is still 'in preview' so I did not think it worthwhile.
Here is what I have observed though - I was trying to get the child feature to work in the context of the same table and this does not appear to be a valid configuration. The relationships and context I was using were valid (Tasks - with Parent Task as the relationship) but I can see how same table could not be supported, as a record could lookup to itself.
I was able to get it working in the context of two distinct tables.

Anyone tried if it supports multi level, I tried but I was not able to get it to work, so it seems to be a limitation to 1 level only?
