Adding a sort to a gallery filter with different data sources

Posted on by Sjj9166

The filter is working perfect - I want to add a sort on the value "Days since last visit" "Days since last visit" but this field is in a collection that is different than the gallery filter.

Filter Source

Filter(HIERARCHY,(CM_Email=vCurrentUser.Email) &&
(StartsWith(StoreType,ThisType) &&
(StartsWith(Store_id,TextSearchBox_1.Text) ||
StartsWith(STORE_NAME, TextSearchBox_1.Text) ||
StartsWith(CITY, TextSearchBox_1.Text))
))

Sort source

ClearCollect(
 ColSession1,
 AddColumns(
 GroupBy(
 Store_Visit,
 "StoreId",
 "Store_Name",
 "DaysSinceLastVisit",
 "Visit_Date",
 "LastVDate"
 ),
 "LastVisitDate",
 Text(
 Max(
 LastVDate,
 Visit_Date
 ),
 "[$-en-US]mm/dd/yyyy"
 )
 )
)

Any thoughts on how to accomplish this?

Thanks

Steve

Hi @Sjj9166

You can use the AddColumns() and Lookup() functions to bring in the date from the second data source as long as there is a common column in both datasources. In the example from the documentation, https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-table-shaping

AddColumns( RealEstateAgents, "Listings", Filter( '[dbo].[AllListings]', ListingAgentName = AgentName ) )

In your case, you would pull in the date from the second datasource.

Hi @Sjj9166 ,

Could you please share a bit more about your scenario?

Is there a relationship between the HIERARCHY data source and the Store_Visit data source?

I assume that the HIERARCHY data source and the Store_Visit data source set up a relationship based on the Store_id column value, is it true?

I have made a test on my side, please take a try with the following workaround:

Set the OnSelect property of the "Sort" icon to following formula:

UpdateContext({SortDescending1: !SortDescending1})

Set the Items property of the Gallery to following:

SortByColumns(
Filter(
AddColumns(HIERARCHY, "DaysSinceLastVisit", LookUp(ColSession1, StoreId = HIERARCHY[@Store_id], DaysSinceLastVisit)),
CM_Email = vCurrentUser.Email, StartsWith(StoreType,ThisType), StartsWith(Store_id, TextSearchBox_1.Text) || StartsWith(STORE_NAME, TextSearchBox_1.Text) || StartsWith(CITY, TextSearchBox_1.Text) ),
"DaysSinceLastVisit",
If(SortDescending1, Descending, Ascending)
)

Please consider take a try with above solution, then check if the issue is solved.

Best regards,

Yes Hierarchy and Colsession1 are related by StoreId but when I try your suggestion I'm presented with no stores. Also what is the '@' before Store_id & what does it do? Thanks again

Hi @Sjj9166 ,

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. I think the formula I provided above is proper.

Please check if the ColSession1 collection is populated with proper records in your app. I assume that you have already executed the ClearCollect(...) formula successfully within your app, and the ColSession1 has been populated with proper records.

In addition, the "@" represents the Disambiguation operator within PowerApps, which could recognize what data source the field is from.

Please check the following article for more details:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/operators#disambiguation-operator

If you do not want to include the "@" operator in your app, please modify your formula as below:

Set the Items property of the Gallery to following:

SortByColumns(
Filter(
AddColumns(HIERARCHY, "DaysSinceLastVisit", LookUp(ColSession1, StoreId = Store_id, DaysSinceLastVisit)), /* <-- Stored_id column is from the HIERARCHY data source */
CM_Email = vCurrentUser.Email, StartsWith(StoreType, ThisType), StartsWith(Store_id, TextSearchBox_1.Text) || StartsWith(STORE_NAME, TextSearchBox_1.Text) || StartsWith(CITY, TextSearchBox_1.Text) ),
"DaysSinceLastVisit",
If(SortDescending1, Descending, Ascending)
)

Please take a try with above solution, then check if the issue is solved.

Note: Also please check if the Store_id column value in your Hierarchy could match the corresponding value in your Colsession1.

Best regards,
