Countrows for gallery

Posted on by Kalakosha

Hi everyone!

help/tell me how to use Countrows correctly in my case.

I have a SharePoint list with the following structure:

Month - choise field, no multi select
TypeEvent - choise field, allow multi select
Chain - choise field, no multi select

Task: at the output I want to get the count of TypeEvent by Chain. Something like that

Chain	TypeEvent1	TypeEvent2	TypeEvent3	TypeEvent4
Chain1	5	3	5	7
Chain2	7	2	4	4
Chain3	2	1	2	3
Chain4	4	4	3	5

I tried the first option:

CountRows(
        Filter(
            R3_APPinChains, Chain.Value = ThisRecord.Chain.Value && Value in ThisRecord.TypeEvent.Value
                )
            )

and realized that it was wrong. Because the output was the following:

Chain	TypeEvent1	TypeEvent2	TypeEvent3	TypeEvent4
Chain1	12	14	5	9
Chain2	12	14	5	9
Chain3	12	14	5	9
Chain4	12	14	5	9

although the numbers caught my attention.
Because before that I counted the total number of events by TypeEventype. And they were like that

TypeEvent1	TypeEvent2	TypeEvent3	TypeEvent4
12	14	5	9

Here I used the following approach that WarrenBelz suggested to me earlier when solving other questions

RenameColumns(
    AddColumns(
        GroupBy(
            Ungroup(
                R3_APPinChains,
                TypeEvent
            ),
            Value,
            Grouped
        ),
        EventCount,
        CountRows(Grouped)
    ),
    Value,
    TypeEvent
)

I have tried in every way to apply this approach to my problem, but unfortunately everything is in vain.
That is why I am asking for help here.
I would be grateful for any help.
Thanks in advance!

Hi @CU08011826-0

I assume that the Month column is not involved here. You will also need to add the actual value of the TypeEvent
DropColumns( AddColumns( GroupBy( Ungroup( AddColumns( R3_APPinChains, Chains, Chain.Value ), TypeEvent ), Chains, Grouped ), TypeEvent1, CountRows( Filter( Grouped, Value = "Type1" ) ), TypeEvent2, CountRows( Filter( Grouped, Value = "Type2" ) ), TypeEvent3, CountRows( Filter( Grouped, Value = "Type3" ) ), TypeEvent4, CountRows( Filter( Grouped, Value = "Type4" ) ) ), Grouped )

Hi, @WarrenBelz,
wow.. this is just great!
thanks for your help!

I got your idea, this will be a good example for future projects.
please tell me, is it possible to substitute the TypeEvent value dynamically, and not specify it explicitly?
I mean here:
Filter( Grouped, Value = "Type1" )

for example, if create a collection for TypeEvent
ClearCollect(colTypeEvents,Distinct(Ungroup(R3_APPinChains,TypeEvent),Value))
and then somehow filter by each value from this collection.
Or is it delusional?

Hi @CU08011826-0,

No - you cannot declare any column name dynamically, for many reasons including for Ungroup, Power Apps needs to validate that the column exists and is a Table field and for AddColumns, it must be a valid name and not already exist - so it does not know what to expect if the value is dynamic.

Hi @WarrenBelz,
yes, everything works fine from the first answer.
strangely, I have already clicked on "Does this answer your question?" at least twice, but for some reason it did not close the item.
thanks again so much!
