[Anonymous]

How to calculate Sum of all DataField from browsegallary. I have tried using formula

Sum(TextBox3)

but it is fetching only first card value . It is not taking values for all card. Suggest some help

Hi, if I understood you question correctly, you should insert a text box outside the data gallery and set its text property to Sum(Source, DataField).  Please see this example:

 

PS The Text( ... , "#,###.00") around the sum is just for formatting

I have filterd the datasource on BrowseScreen. Now I want calculate the result based on filtered data that currently showing on BrowseScreen

How about Sum(Filter(Source, XXX  > YYY), DataField) where XXX > YYY is the same filter condition as the gallery?

Alternatively you can:

1. Put your filtered records in a collection with ClearCollect
2. Set the Items of your gallery to this collection
3. Set the sum text box to show the sum of the collection's data field

What is the event/trigger for the filtering of the data source?

If you post some screenshots or formulas it may be easier to help you.

I was trying to do this too. Did you get an answer outside of the forum on how to perform a SUM based on a filter? (I don't have a gallery in my case, I'm just summing data from a data source.)

Hi Audrie,

Assuming for example you have a data source "ShoppingCart" with at least one numeric column e.g. "Price", and you want to sum over a filtered view of the the data source, e.g. if Price < 1000:

    = Sum(Filter(ShoppingCart, Price < 1000), Price)

Alternatively you can also fold the filtering logic into the aggregator itself:

    = Sum(ShoppingCart, If(Price < 1000, Price, 0))

Please do keep in mind however that aggregators such as Sum, Average, etc -- are not yet delegated to the data service back-end. This means they can only operate on up to 500 rows of data at the moment, until PowerApps gets aggregate query delegation support.

Thank you.

Do you know if  "aggregate query delegation support" is planned this fiscal year or not?

We are actively working on this feature. We will ship it as soon as it's finalized and deemed rock-solid.

Thanks for your patience.

Thanks for all of your help!

You need to be specific about the column name.

This works as follows:

    Sum(Collection; [@ColumnName])    - Comma separators don't work for me (en-ZA)

    ~ or ~

    Sum(Collection, [@ColumnName])   - Comma separator seems commonplace for all other users
