如何使用 PowerApps 更新两个 SP 列表项

Question

We would like to connect 2 Sharepoint lists to one PowerApps gallery. So editing in in Form 1 with SP list 1, and then editing in Form 2 with SP list 2. The Title column in List 1 and List 2 are the same.

The gallery list is showing "Gallery.Selected" the filter is:

SortByColumns(
  Filter(
    [@BICT_DATA_KLANTEN_MAIN]; 
    StartsWith(
      Title; 
      ZOEKBALK_BICT_DATA_MAIN.Text
    )
  ); 
  "Title"; 
  If(
    SortDescending1; 
    Descending; 
    Ascending
  )
)

Answer 1

Its difficult for me to answer this question succinctly. There are SO many factors at play. To connect two Sharepoint lists to a single Gallery control, combine the lists into a single Collection.

Example:

ClearCollect(colCombined,
    SPList1,
    SPList2
)

• Add colCombined to the Items property of the Gallery.
• But this will add ALL records from both SP Lists.
• You likely don't want this because of unnecessary columns, size of data, etc.

Considering the Form controls you mentioned, put some thought into the relationships between List1 and List2. I'm imagining you want a Header - Details -type of relationship.

• Personally, I remove the Title column from Sharepoint lists then use a recordGUID column. Its more intuitive for me and others that come after me to maintain the app. "Title" says nothing about "ID key needed to relate lists".
• Research the PowerApps GUID() function. You'll want to populate the recordGUID column of both lists when creating new records.
• There is a 1-2hr class worth of nuance involved in creating a Header/Details type of application. From the UI to the Sharepoint best practices to the PowerFX code.
