Filter a form based on Gallery selection

(0) ShareShare
ReportReport
Posted on by Community Power Pla...

I have an app with 3 screens & 2 data sources ("Properties" & "Spaces")

When I switch to screen 3 by clicking "Space Availability" button, I would like to present data from "Spaces" related to selected record.

 

• 1st screen: gallery(BrowseGallery1) which contains all Properties (data source=Properties)

• 2nd screen: form w/details of the selected property (data source=Properties)

• 3rd screen: form w/details on the spaces available in the selected property (data source=Spaces)

 

I am having trouble with the form on the 3rd screen, it will not display any data. 

This is the formula I have which does not work

Filter(Spaces, spacestoprop = BrowseGallery1.Selected.PrimaryId)

•spacestoprop is the lookup on the Spaces entity

 

New to PowerApps, any help would be greatly appreciated.

    Is there one and only one record in Spaces for each Property? Is that record created already?

     

    If you have a form you only want to display one record, so the Item property of the form should be a Lookup, not a Filter (Filter gives many records, Lookup only one).

     

    If you want to show all the records, use a gallery instead of a form; then your formula ought to work.

     

    Can you share some screen shots, showing where it goes wrong?

    Ah I see what you mean. The problem is, there are several Space records for each Property. My mistake, I thought a form would give me a list of all the Spaces available for that specific property. Now I tried creating and filtering the gallery and this is what i get.Capture.PNG Highlighted operation is not supported by column 'spacestoprop'.

    It seems I was missing part of the formula. My new formula looks like this and it's working

    Filter(Spaces, spacestoprop.PrimaryId = BrowseGallery1.Selected.PrimaryId)

     

    Thanks for the info on forms!

    I'm encountering the same issue but I'm unsure where you defined your spacestoprop lookup. I'm very new to PowerApps but I'd like to accomplish the same thing you described.
