Update Collection PowerApps

Updating a Power Apps collection typically involves adding, modifying, or removing records from the collection based on user actions or other events within the application.

Suppose you want to update the collection item in Power Apps; you can use two different functions. Such as:

  1. Update: The Power Apps Update Function is used to replace the entire record in a data source
  2. UpdateIf: The Power Apps UpdateIf Function is used to modify one single or more values in one or more records that match one or more conditions

1. PowerApps Update Function Syntax:

Update( DataSource, OldRecord, NewRecord [, All ] )


  • DataSource = This contains all the records that you want to replace. It may be a Table, Collections, etc
  • OldRecord = It is the record that you want to replace
  • NewRecord = It is the replacement record. This is not a change record. Here, the entire record is replaced
  • All = Mention the All argument to remove all copies of the record

2. PowerApps UpdateIf Function Syntax:

UpdateIf( DataSource, Condition1, ChangeRecord1 [, Condition2, ChangeRecord2, ... ] )


  • DataSource = This data source contains one or more records you want to modify
  • Condition(s) = In this condition, you can use column names of DataSource in the formula. It evaluates to True for the record that you want to modify
  • ChangeRecord(s) = You can provide a change record of new property values that satisfy the condition
