Hey All, Any idea if that is possible OOTB?  Or any way to achieve that? I have a table with IDs that appear a few times. I wold like to paint the row(s) in a table visualisation for each group of...

    Anonymous Man, this one does not want to give in!  :smileyhappy:
    I am guessing you have filters from other tables flowing into your visual which I think is causing the problem.  I have updated the measure and as far as I can tell it is working with all scenarios.

    Fomatting Measure = 
VAR CurrentID = SELECTEDVALUE(Table1[ID])
VAR FilteredCount = 
    CALCULATE(
        COUNTROWS ( 
            FILTER ( 
                VALUES(Table1[ID]), 
                Table1[ID] > CurrentID
            )
        ),ALLSELECTED()
    ) + 1
VAR FilterTrap = COUNTROWS(VALUES(Table1[ID]))
RETURN IF ( NOT ISBLANK( FilterTrap ), IF ( ISINSCOPE(Table1[ID]), IF ( ISODD ( FilteredCount ), "#7195BE", "#68CCE4" ) ) )

    Sample file here: https://www.dropbox.com/s/y230n9u0wo08wjp/IDFormatting.pbix?dl=0
    Here is a view with filters applied from both the table itself and from a related date table and it still works.

    A calculated column is not an option because the calc is static and if you filtered out an even row but left the two odd rows on either side the calculated column would not update to change the coloring.  Our measure will since it is a count based on the visable IDs.

EDIT:
Sorry, not working well as I thought.

Maybe I am missing something?

For example (Table sorted by ID)

Amazing!
Can you please explain the logic behind the DAX?

Reading it again and again for the last 10 minutes, and not sure I understand it completely.

Understood the basic logic of counting the rows until current row, but want a more technical explanation, if possible.
Thanks a lot,
A

Anonymous , lets try something a bit more dynamic.

Add a measure to your model that we will use to apply the formatting.

Fomatting Measure = 
VAR CurrentID = SELECTEDVALUE(Table1[ID])
VAR FilteredCount = 
    CALCULATE(
        COUNTROWS ( 
            FILTER ( 
                VALUES(Table1[ID]), 
                Table1[ID] > CurrentID
            )
        ),ALLSELECTED()
    )
RETURN 
IF ( ISINSCOPE(Table1[ID]), IF ( ISODD ( FilteredCount ), "#7195BE", "#68CCE4" ) )

The colors we are using are listed in the measure, then we apply the formatting based on the value of the measure:

    Hey jdbuchanan71 

    Not sure how you are doing it. I am not able to format according to a measure. Only a column.

    So I am back to square 1 again.

    I tried to put your DAX in a column, but it returns empty.

     

    Cheers,
    A

      Anonymous , That is very strange.  I have uploaded a copy of my testing file here.  Does the formatting work in this file for you?

      https://www.dropbox.com/s/y230n9u0wo08wjp/IDFormatting.pbix?dl=0

      Perhaps you need to update your PowerBI desktop app?

      The file also includes the formatting calc as a column in the table if you need it.

        Hi jdbuchanan71 

        Yes, strange. Restarted my machine... the ultimate solution. :catwink:

        Anyhow, I am getting the same results with the measure.

        Different consecutive IDs are getting the same color code.

        Table is sorted by IDs.

        Thanks!
