sort with distinct

Is it possible to combine in one function DISTINCT and SORT? And how can it be possible to create a Collection using distinct?

You would have to nest it. 

 

The Items property of a gallery or dropdown would look like:

Sort(Distinct(datasource,column to find distinct records), column for sorting, ascending/descending)

 

You would collect what you want and the formula above would sort it after the fact.

 

That said, with the April 29 update to PowerApps, your datasource may not load entirely if you use both of those functions together since they have worked in "delegation."

I tried a lot, and come to this:

Sort(Distinct(Source,Column),Result)

Sort(Distinct(Source,Column),Result) - Worked good for me. I additionally added the if statement  to switch the order.

 

Sort(Distinct(Source,Column),Result,If(SortDescending1, Ascending,Descending))

 

Thanks!

Where is the documentation for this? I cannot find how I should have known "Result" would just allow it to sort the column I performed the Distinct() operation on. It would not work with the column name. Required "Result" to be there.

I found it in the 3rd sentence of the Distinct function documentation highlighted in bold  😋  In my opinion though it should just be in a column called value like everything else.  Why can't life be simple?

Thank you! I was looking in the SORT documentation.

Ahhhhhh. That's why.  I understand now.  I think there's a few other functions that behave this way.  Split and Concatenate are two examples.  I can't recall if there's any others at this moment.

For me the way that works is:

Distinct(Sort(Filter('Source';true).Column;Column;Ascending);Column)
