PowerApps get row count having numbers in single column table


In Power Apps, the Count function is used to return the number of records that contain number in a single column table. This function is particularly useful when you need to determine the size of a dataset or apply logic based on the number of records.

PowerApps – Count() function Syntax

Count(SingleColumnTable)

  • SingleColumnTable: The table or collection for which you want to count the number of records.

Notes:

  1. This function doesn’t consider blank or null values.
  2. Delegation: Be mindful of delegation limits when using the Count function with large data sources. Ensure that your formulas are delegable to handle large datasets efficiently.
  3. Performance: For large datasets, consider using indexed data sources or applying filters to reduce the number of records before counting.
  4. Error Handling: Handle cases where the count might be zero to avoid displaying misleading information or causing errors in the app.
  5. Conditional Logic: Implement conditional logic based on the number of records, such as showing a message when there are no records or enabling/disabling controls based on the count.

PowerApps - Count Records in a Collection

Suppose you have a collection named Products and you want to count the number of records in this collection.

  1. Create the Collection:

ClearCollect(Products,

    Table(

        {ProductPrice: 1000},

        {ProductPrice: 500},

        {ProductPrice: 300}

    )

);

  1. Count the Number of Records:
    • Add a Label control.
    • Set the Text property of the Label to:

Count(Products)

This will display the number of records in the Products collection, which is 3.

PowerApps - Count Filtered Records

You can use the Count function in combination with the Filter function to count only those records that meet certain criteria.

  1. Filter and Count the Records:
    • Add a Label control.
    • Set the Text property of the Label to:

Count(Filter(Products, Price > 400))

This will count the number of products with a price greater than 400, which in this case is 2.
