Specific record from collection

[Anonymous]

Hi,

I am trying to figure out how to display a record from a collection, only if there is data in the collection. 

I have a input box where the user writes Licance plates, several at a time.

The plate numbers are stored in a collection. - This all works fine.

The challange arrises when I retrive the plate numbers from the collection.
They will be shown in a Label, with strict system formating. The information in the label will, when finished, be sent out as an email. 

In order to keep to the system format, the plate number have to follow this format:

Plate 1, Plate 2 Plate 3

Plate 4, Plate 5, Plate 6

Plate 7, etc...

How do I get the plate numbers to show one by one and backspace after three entries?

I have tried Last(FirstN(collection, 1).column. This works if I know how many records there will be, but if there only is one or two records, the last plate shows up for each of the remaining Last(FirstN(collection, #) in the formula.

Any ideas?

Hi @Anonymous 

One simple option would be to use a gallery to display the data in the collection and set the wrap cound for gallery to 3 so it will place 3 items in a row

Second option you would need an index (ID) for all your collection items

So lets say you have a collection like

ClearCollect(colPlates,{ID:1,Title:"Plate1"},{ID:2,Title:"Plate2"},{ID:3,Title:"Plate3"},{ID:4,Title:"Plate4"},{ID:5,Title:"Plate5"},{ID:6,Title:"Plate6"},{ID:7,Title:"Plate7"})

Then all you need to do for label is use

Concat(colPlates,If(Mod(ID,3)=0, Title & Char(13), Title &","))

Hi @Anonymous ,

I quite agree with @RezaDorrani ’s second option.

I have made a test , and some additions are made because the I found it ends with a comma sometimes.

First, the ID Column is needed to be indexed.

Second, Use concat function to format the label text.

Third, determine if there is a comma at the end and replace it with blank if is.

Please refer to following formula:

If(Mod(Last(Collection).ID,3)=0,Concat(Collection,If(Mod(ID,3)=0,PlateNo&Char(13),PlateNo&",")),Substitute(Concat(collection,If(Mod(ID,3)=0, PlateNo&Char(13),PlateNo&",")),",","",(RoundDown(Last(collection).ID/3,0)*2+Mod(Last(collection).ID,3))))

Best regards,

Sik

Thank you @RezaDorrani and @v-siky-msft 

I got it working with: Concat(colPlates,If(Mod(ID,3)=0, Title & Char(13), Title &","))

Hi @RezaDorrani ,

Thanks for your help first time around.

I have encountered another issue.

When I use your setup, it all works fine until the user starts deleting items before hitting send.

Current format of:

Plate1, Plate2, Plate3

Plate4, Plate 5, Plate6

Plate 7, Plate 8, and so on…

If ID #3 is removed due to typo, it is formatted like this:

Plate1, Plate2, Plate4, Plate5, Plate 6

Plate 7, Plate8, and so on…

Any suggestion on how to either Patch ID or getting this to work?

Thank you!
