How to showing data in 2 different Galleries from different SharePoint Lists?

[Alan78]

Hi,

I am hoping someone can help me solve an issue I am having when trying to relate 2 different Gallery Controls to each other.

The idea is that I have 2 Screens on a mobile App that both have Gallery Controls.

When you select an item on Screen 1 in Gallery 1 you navigate to Screen 2 and see all the items in Gallery 2 that relate to the item you selected on Screen 1. This would be straight forward if all my data was in the same Sharepoint list but it's not.

I currently 1 SharePoint List and 1 SharePoint Document Library.

Screen1/Gallery1 shows data from the SharePoint List and has a PrimaryKeyID

Screen2/Gallery2 should show all items related to the item in Screen1 within a SharePoint Document Library which contains a ForeignKeyID.

I have tried creating a Lookup on the Gallery2 Item propery but I just can't get it to work.

How do I create a function to do this in PowerApps?

This was my poor effort: 😞

LookUp(SharePointDocLib, varPropID=BrowseGallery1.Selected.PropertyID);

Hope someone can help.

Thanks...

Hi @Alan78
Not a poor effort - you were almost there - the Items property of your gallery (I am assuming all your other control and field names are valid)

Filter(
   SharePointDocLib, 
   varPropID=BrowseGallery1.Selected.PropertyID
)
