ClearCollect & Filter

Posted on by MR-14011956-0

I'm new to PowerApps. I had someone in my company who was very capable recently leave, so my source of review/corrections has also left. ChatGPT is not helping me solve this issue either as I've exhausted the troubleshooting and everything checks, so looking to you for help as I'm not getting the expected results.

I am building an app that collects and displays data. Screen1 has a dropdown list of projects (FilterDrop_ProjectName), which then populates a gallery (GalleryDesignPackageCategories) which is a checkbox list of categories. A user would then pick the categories they would like to see, and it populates the package details in another gallery (Gallery4).

FilterDrop_ProjectName OnChange property I have:

UpdateContext({filteredProjectName: Trim(FilterDrop_ProjectName.Selected.NewProjectName)})

GalleryDesignPackageCategories (the gallery), Check_ProjectCategory (the repeating check box populated by ProjectName) OnCheck property I have:

Collect(SelectedPackageCategories, ThisItem.Value)

Table '[DPC] Design Package Coordinations' has the following columns:

ProjectName - Text

PackageCategory - Text

Screen1 OnVisible property I have:

ClearCollect(
    colGallery4Data,
    Filter(
        '[DPC] Design Package Coordinations',
        ProjectName = filteredProjectName && PackageCategory in SelectedPackageCategories
    )
);
 
When I add a text label to count the rows of colGallery4Data, it ends up as 0, but it should return 8. I've reduced the ClearCollect to try and show just ProjectName or PackageCategory, but no matter what it comes back 0, and won't populate my Gallery4 content. What's wrong with my ClearCollect or Filter functions?

OK - I see now your gallery is a one-field item with (I assume) the checkboxes displaying the Value field, so for the last Collection
With( { _Data: Filter( '[DPC] Design Package Coordinations', ProjectName = filteredProjectName ) }, ClearCollect( colGallery4Data, Filter( _Data, PackageCategory in SelectedPackageCategories.Value ) ) );

Thank you for the response and help! Ok, I had that code on OnCheck of Check_ProjectCategory, but you're saying I should instead put it on OnSelect of GalleryDesignPackageCategories? I have tried that, but there is still no change. I currently put it back to OnCheck of Check_ProjectCategory. Here's the other codes you asked about:

Items for GalleryDesignPackageCategories:

Distinct( Filter( '[DPC] Design Package Coordinations', ProjectName = FilterDrop_ProjectName1.Selected.NewProjectName ), PackageCategory )

Default for Check_ProjectCategory:

false

Default for GalleryDesignPackageCategories:

false

@MR-14011956-0,

The key here is the change I made to the OnSelect of the checkbox in the Gallery, assuming you had records in there to select
Collect(SelectedPackageCategories, ThisItem)

What is the Items of GalleryDesignPackageCategories and the Default of Check_ProjectCategory ?

Thank you @WarrenBelz.

I did make the suggestions that you have made. Because PackageCategory wasn't recognized after SelectedPackageCategories, I updated to this:

With( { _Data: Filter( '[DPC] Design Package Coordinations', ProjectName = filteredProjectName ) }, ClearCollect( colGallery4Data, Filter( _Data, PackageCategory in SelectedPackageCategories ) ) );

Could that small update have an impact on my results?

Besides that, I've restarted the app and I continue to get nothing back:

colGallery4Data rows: 0

Hi @MR-14011956-0

Firstly (small improvement on this one) - FilterDrop_ProjectName OnChange
UpdateContext({filteredProjectName: Self.Selected.NewProjectName})

GalleryDesignPackageCategories - Check_ProjectCategory OnCheck
Collect(SelectedPackageCategories, ThisItem)

Screen1 OnVisible (I assume you are changing to this after you set the items above)
ClearCollect( colGallery4Data, Filter( '[DPC] Design Package Coordinations', ProjectName = filteredProjectName && PackageCategory in SelectedPackageCategories.PackageCategory ) );

If you are concerned about Delegation on the last one
With( { _Data: Filter( '[DPC] Design Package Coordinations', ProjectName = filteredProjectName ) }, ClearCollect( colGallery4Data, Filter( _Data, PackageCategory in SelectedPackageCategories.PackageCategory ) ) )
