Linked collection gallery showing the same items regardless of which master item is selected

Hello,

 

On my app, I have a button on my home screen that creates a new item on another screen - the fx I'm using for the OnSelect propety of this button is: 

 

//sets item as new and sets colTopicClaim collection
NewForm(DocData_form);ClearCollect(colTopicClaim, {Topic: "", Claim: "", TopicRAGStatus: ""});

//get the record
Set(
    varCurrentRecord,
    Defaults(DocData)
);

//go to new item screen
Navigate(FormScreen,ScreenTransition.Cover)

On selecting this button, I am taken to my form screen where as Highlighted in Yellow, I have my SharePoint editForm control and Highlighted in Red I have a gallery where the items property is set to colTopicClaim

sudosaurus_2-1693474802286.png

I add items to the colTopicClaim gallery using the "+ New Topic" button which loads a modal with these fields:

sudosaurus_3-1693474880071.png

Using the "Add Topic" button I am able to add new items into the gallery - fx:

 

RemoveIf(colTopicClaim, Topic = "" And TopicRAGStatus = "" And Claim="");

Collect(
    colTopicClaim,
    ThisItem,
    {
     Topic: Topic_dd.Selected.Value,
     TopicRAGStatus: TopicRAGStatus_dd.Selected.Result,
     Claim: Claim_TextInput.Text
    }
);

UpdateContext({varTopicClaim: false})

 

Items appear in the gallery like this:

sudosaurus_4-1693474959344.png

When I use the "Save" button at the top of my screen - the SharePoint item is saved and for the OnSuccess property of the form I have this fx which patches the data in the colTopicClaim gallery to the colTopicClaimSP SharePoint list.

 

ForAll(colTopicClaim, Patch(colTopicClaimSP, Defaults(colTopicClaimSP), {spTopic: With({wTopic: LookUp(Topics As Inner, Inner.Topic = Topic)}, {Id: wTopic.ID, Value: wTopic.Topic}), spClaim: Claim, spTopicRAGStatus: TopicRAGStatus, DocDataID: DocData_form.LastSubmit.ID}))

 

 Back on my home screen, I have a green button that allows me to view saved SharePoint items as well as their linked collection records in the app: 

sudosaurus_5-1693475134921.png

The OnSelect property of this button is set to:

 

// Get the record from 'Document Data'
Set(
    varCurrentRecord,
    LookUp(
        DocData,
        ID = ThisItem.ID
    )
);

// Get the related record from 'colTopicClaimSP' using the ID from 'Document Data'
Set(
    varLinkedRecord,
    LookUp(
        colTopicClaimSP,
        DocDataID = ThisItem.ID
    )
);

// Go to item screen
Navigate(
    FormScreen, ScreenTransition.Fade,
    {locFormDisplayMode: "Edit"}
);

 

However, when selecting this item, I am taken to the SharePoint item but see the same collection results in the gallery for each item - it doesn't display the related item via varLinkedRecord.


This should work as my DocData (SharePoint list) is saved as follows:

sudosaurus_6-1693475287772.png

and my colTopicClaimSP (SharePoint list) is saved and contains the DocDataID which is the same as the ID from the DocData list. 

sudosaurus_7-1693475331750.png

 

Could someone help me work out why the correct data isn't loading.

 

Thanks!

 

@Shanescows - any ideas with this one?

Hi @sudosaurus 

 

Looks like something is wrong with the LookUp function that why you see the same collection results in the gallery for each item and it doesn't display the related item via varLinkedRecord.

Im kind of curious are the DocDataID.ID and colTopicClaimSP.DocDataID in the Sharepoint list Data type: Text?

 

Then the lookup would look like:

 DocDataID 

LookUp(
        DocData,
        ID = Text(ThisItem.ID)
    )

 colTopicClaimSP

    LookUp(
        colTopicClaimSP,
        DocDataID = Text(ThisItem.ID)
    )

 

 Please let me know if this works.

@SpongYe  - DocData.ID is the SharePoint list ID field. DocDataID in the colTopicClaimSP list is of the type "Single line of text".


I have tried adding the above to the OnSelect of the "New Report" button, however when being navigated to the form screen, the collection always shows the same data regardless of which item was selected - only the sharepoint form is showing the correct data.

@sudosaurus 

 

We need to change the OnSelect of see picture below and not the OnSelect of the "New Report" button.

 

PowerYsa_0-1693518481568.png

 

Because varCurrentRecord and varLinkedRecord doesnt contain the right DocDataID.ID and colTopicClaimSP.DocDataID.

@SpongYe - I have made some changes since my last reply.
On the OnSelect of the gallery on my home screen, I am using Set(varItem, ThisItem); and then on my SharePoint form on the other screen (where I enter the data), in the Items value of the EditForm control I have set this to varItem - this means when I load my item from the gallery on the home screen, the SharePoint form is loaded.

However, the collection gallery is still not loading, regardless of trying what you suggested above. 

Just so we're clear, in the screenshot below, the section on the left with the two drop-downs and Claim text field are standalone controls (not part of a form or gallery) - these Collect data into the colTopicClaim Collection:

sudosaurus_0-1693519248997.png

Collect(
    colTopicClaim,
    {
     Topic: Topic_dd.Selected.Value,
     TopicRAGStatus: TopicRAGStatus_dd.Selected.Result,
     Claim: Claim_TextInput.Text
    }
);

Ideally Id like saved values to be loaded into the colTopicClaim Collection gallery when the item is selected from the previous screen (just like the SharePoint form is).

 

For reference, the colTopicClaim Collection is in the colTopicClaim_Glly (Gallery) where the Data source equals colTopicClaim (which is my collection). The Items value for this collection is also set to colTopicClaim.

I was hoping I could do some wizardry with changing the Items property to something like varLinkedRecord.ID = Buildings_glly.Selected.ID - however that doesn't work.

 

I've been struggling with this for yet another day and don't know what to do next 😕
It seems so simple yet so complex.

So you're having a few problems here: 

 

1. However, the collection gallery is still not loading, regardless of trying what you suggested above. 

 

2. Ideally Id like saved values to be loaded into the colTopicClaim Collection gallery when the item is selected from the previous screen (just like the SharePoint form is).

 

3. I was hoping I could do some wizardry with changing the Items property to something like varLinkedRecord.ID = Buildings_glly.Selected.ID - however that doesn't work.

 

Let's break it down otherwise I don't know what to focus on. 

I will and can help you but based on the information I am kind of lost what to focus on. 

 

Give me problem and a use case I can reproduce and I will find a solution to help you.

Alright.

 

I have two dropdown's and one text control that I need to add entries to a collection - I use this fx on my 'Add Topic' button: 

 

 

RemoveIf(colTopicClaim, Topic = "" And TopicRAGStatus = "" And Claim="");

Collect(
    colTopicClaim,
    {
     Topic: Topic_dd.Selected.Value,
     TopicRAGStatus: TopicRAGStatus_dd.Selected.Result,
     Claim: Claim_TextInput.Text
    }
);​

 

 

  1. This collection is saved to a SharePoint list - in my scenario this is working correctly.
  2. I have two SharePoint lists - one a SharePoint EditForm control is saved into and another where my Topics collection is saved into (2.) - the list that the collection is saved to has a column named 'DocDataID' that stores the ID of the other list - this is done through the patch of the collection on the OnSuccess property of the SharePoint EditForm control.
  3. I have managed to load my SharePoint form through the app onto my FormScreen, however I've been unable to load my previously saved collection to the same screen.
  4. I need to load the collection from the OnSelect of the Home screen - this is the gallery of the items in the DocData SharePoint EditForm list - the ID of each item in this list is also in the colTopicClaim list under the column 'DocDataID' (as mentioned above).
    This needs to display in a gallery on my form screen (as per my previous post) so that when viewing the form, users can see previously added Topics, yet still have the ability to add additional topics that they can then save back to the colTopicClaim list.

Essentially it's getting this colTopicClaim gallery sorted and loading on the Form screen.

@SpongYe - if I change the Items property of the gallery to:
Filter(colTopicClaimSP, DocDataID = Buildings_glly.Selected.ID)

Then, the topics are displayed for the Data saved in SharePoint, however I'm unable to add new items into a collection on the same screen without visually seeing them entered.

 

Now I understand why this is so complex!

Ah @sudosaurus , I think I found the problem. 

On your initial post you have a ClearCollect function in your code. 

ClearCollect(colTopicClaim, {Topic: "", Claim: "", TopicRAGStatus: ""});

Please see your message here:

PowerYsa_2-1693526596439.png

The ClearCollect removes every record in the collection. 

Now the question is if the ClearCollect is still necessary given that you are now using standalone controls.
