Sort gallery with multiple fields

I have a sharepoint list called: "Events", for all my events We have also a list called:"Locations".

 

In the list called events, it is a loockup field to "Locations" where the title describe the location of the event.   In the "Events" field we do also have 2 choice fields one for membership ("Gold";"Silver";"Bronze")  and one for branch ("IT", "Financials", "Production","Logistics").  The last field "Event manager" is a user field with lookup to Azure AD. 

 

I need to create a gallery, where i can sort on several values at the same time like "Locations";"Branch"; "Membership". or sort on "Event Manager", "Branch";"Location". 

 

I have tried SortByColums, but there is a problem sorting on sharepoint lookup fields, choice fields, or Person field.   What is the best practice and how should the formula look like to sort on several field at the same time.  It is a lot of items, so it must be a delegated sort (an mybe a filter).

Re: Sort gallery with multiple fields

Hi @TrulsB 

 

For lookups, choice and person

 

Create equivalend text fields in the data source

Probably - run a flow to first update all existsing items with the new text field columns

 

Then in your existing form control in PowerApps, add the 3 new text columns and set their default values with respect to their associated columns and hide these columns on the form

 

Next ensure to have column indexes created for all columns you are sorting and/or filtering on

indexing ensures you do not run into the 5000 item issue

 

And then ensure all your queries in powerapps support delegation

Re: Sort gallery with multiple fields

Hi @TrulsB 

 

In that you can build the expression as:
 
SortByColumns(AddColumns(Events, "LocationName", Location.Name, "BranchName", Text(Branch), "MembershipName", Text(Membership), "ManagerName" , 'Event Manager'.FullName), "LocationName",Ascending, "BranchName",Ascending,"MembershipName",Ascending,"ManagerName",Ascending)
 
Here, You need to first convert the lookup/choice type columns into simple text fields and then the sort can be performed easily.
 
If this differs from what you are looking for, please share more details so that we might be able to help you better.
 
Hope this Helps!

Re: Sort gallery with multiple fields

The formula looks good, but i get a delegation warning after i inserted text(  ... ) in the SortByColumn...It is a lot of items in the list  (more than 10 000 within a year).   How can i buypass the delegation problem? Is it to convert the actual lookup field to text field on the item level,  eg, i create a text field called LocationTxt and update this with values from the Location field ?

 

The sharepoint form is modified with PowerApps and we have several apps on this list created in Powerapps.  If the solution is to create text fields used by SortByColumn, what is the best practice to update values in the text fields - with values from choce fields (Location -> LocationTxt).

Re: Sort gallery with multiple fields

Hi @TrulsB ,

Could you please share a bit more about the Delegation issue with your formula?

 

If you want to sort your Gallery Items based on the Choice, LookUp, or Person type column using SortByColums function, I think there is no direct way to achieve your needs.

 

As an alternative solution, I think the AddColumns function could achieve your needs. Please set the Items property of the Gallerty to following:

SortByColumns(
AddColumns(
Events,
"LocationName", LocationColumn.Value, /* LocationColumn represents the LookUp column in your SP list */
"BranchName", BranchColumn.Value,
"MembershipName", MembershipColumn.Value,
"ManagerName" , 'Event Manager'.FullName
),
"LocationName", Ascending,
"BranchName", Ascending,
"MembershipName", Ascending,
"ManagerName", Ascending
)

Note: Please set the "Data row limit for Non-delegable queries" option within Advanced settings of App settings of your app to maximum value -- 2000.

If the amount of your SP List records is not more than 2000, you could ignore the delegable warning issue within your above formula.

 

Currently, within PowerApps, the complex type columns (e.g. Choice, LookUp, Person, ... etc) is not delegabled within SortByColumns function or Sort function. Please check the following article:

https://docs.microsoft.com/en-us/connectors/sharepointonline/#powerapps-delegable-functions-and-oper...

 

If the amount of your SP list records is more than 2000, please consider take a try with the following workaround:

1. Add a Calculated type column -- 'IndexRow' within your SP list, set the Formula to following:2.JPG

2. Then you could bulk-load your SP list records into your app based on the 'IndexRow':

Set the OnStart property of the App to following (I assume that there are 10000 records existed in your SP List😞

Concurrent(
               Collect(Col1, Filter(Events, Value(IndexRow)>=1 && Value(IndexRow)<=2000)),
Collect(Col2, Filter(Events, Value(IndexRow)>=2001 && Value(IndexRow)<=4000)),
Collect(Col3, Filter(Events, Value(IndexRow)>=4001 && Value(IndexRow)<=6000)),
Collect(Col4, Filter(Events, Value(IndexRow)>=6001 && Value(IndexRow)<=8000)),
Collect(Col5, Filter(Events, Value(IndexRow)>=8001 && Value(IndexRow)<=10000)) );
ClearCollect(MergedCollection, Col1, Col2, Col3, Col4, Col5)

Then modify above Filter formula as below:

SortByColumns(
              AddColumns(
                         MergedCollection, 
                         "LocationName", LocationColumn.Value,    /* LocationColumn represents the LookUp column in your SP list */
                         "BranchName", BranchColumn.Value, 
                         "MembershipName", MembershipColumn.Value, 
                         "ManagerName" , 'Event Manager'.FullName
              ), 
               "LocationName", Ascending, 
               "BranchName", Ascending,
               "MembershipName", Ascending,
               "ManagerName", Ascending
)

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