Measure to display value only if "All" is selected, otherwise return blank

[andrehawari]

Hi, I need to create a measure that have the opposite function in this links

https://community.powerbi.com/t5/Desktop/Visualisations-blank-until-something-selected-in-a-slicer/t...

Basically I want to make the the value is blank when certain value is selected, but it display value only if all is selected

Please the find the image below,

When Category is Selected,  and SubCategory=All, the Value2 is displayed

However, if ANY of the SubCategory is selected, I want to make the Value2 is BLANK

.

My idea was creating a measure like this (below is just pseudo code)

Value2Measure= 

var parameter=selectedvalue(Table[SubCategory]

return 

IF(parameter=  something All selected , sum(value2), else if any of the value is selected, blank())

Any idea would be really appreaciated, Thanks !

Please, try this measure for value2

SumValue2 =
VAR NumberFilterCategory =
    COUNTROWS ( VALUES ( TestData[CATEGORY] ) )
VAR NumberFilterSubCategory =
    CALCULATE (
        COUNTROWS ( VALUES ( TestData[SUBCATEGORY] ) );
        ALLEXCEPT ( TestData; TestData[SUBCATEGORY] )
    )
RETURN
    IF (
        NumberFilterCategory <> NumberFilterSubCategory;
        SUM ( TestData[VALUE2] );
        BLANK ()
    )

I have these results

 

my test data was the pic below

Is this work for you????

Thanks A lot !

I also getting another approach, but it take 2 measures instead of 1

slicerallselected =

var totalslicervalue = calculate(DISTINCTCOUNT(Sheet1[SubCategory]),ALL(Sheet1[SubCategory]))
var countselectedvalue= calculate(DISTINCTCOUNT(Sheet1[SubCategory]),ALLSELECTED(Sheet1[SubCategory]))

return

IF(totalslicervalue=countselectedvalue,1,0)

Value2Measure = switch([slicerallselected],1,sum(Sheet1[Value2]),0,blank())

you can test both to see what is works better with your data (performance issues).

you can see this video to check how both measures perform with you data
