Movie Directory Part 2: Gallery and Filters

In Movie Directory Part 1, I described what I was aiming to achieve with this personal project, as well as the Dataverse structure.

In this post, I’ll describe at a high level the design of the Power App and the gallery view and filters. Most of it I’ll keep at a high-level, not step-by-step, as I used a lot of the out-of-the-box functionality.


There are four screens involved in the app:

  • Gallery view that shows all of the movies, with the cover art behind the title, year, and last time we watched it
  • Filters screen that allows you to specify filters that apply on the gallery view
  • View details screen of a single movie
  • Edit details screen of a single movie, including a new movie

All Movies

Gallery view. We own all the Alien movies.

The majority of this screen is a Gallery component, with some minor changes to show exact details I wanted to show. The biggest change is incorporating the filters from the filters screen, which required this in the OnVisible field to handle whether there are filters set or not:

Set(MoviesFilter2,If(!IsBlank(varOwned),Filter(MoviesFilter1,varOwned in Owned),MoviesFilter1));
Set(MoviesFilter3,If(!IsBlank(varLastWatched),Filter(MoviesFilter2,'Last Watched'>=varLastWatched||IsBlank('Last Watched')),MoviesFilter2));

And this in the Items field to only show those with the right filters:

    If(IsBlank(TextSearchBox1.Text),MoviesFilter3, Filter(Movies,TextSearchBox1.Text in Text(Name))),
        If(SortDescending1, SortOrder.Descending, SortOrder.Ascending)

The OnSelect field of the Overlay on the gallery has this, to navigate to viewing that specific movie:


Setting the background image was a bit simpler, putting this into the Image field of the Image component in the Gallery:


Another minor tweak included adding the Filters icon, which navigates to the filters screen with this formula in the OnSelect:



Filters screen

The filters screen is nothing flashy, but functional. The watchlist field is a simple dropdown, where the items field comes from the Dataverse tables:


Similar for the Owned Platform field:


Hide Movies Watched Since is a standard date picker field, but those are hard to blank out if you had that set and then wanted to turn it off, so I had to add an accompanying button with this OnSelect value:


The hardest part is the Save button, which needed to update the filter variables and navigate back to the gallery view, so this goes into the OnSelect for that button:


That’s it for the gallery view and filtering. The next post in this series will describe viewing and editing of a single movie.
