Custom Slicer using DAX

[Anonymous]

I have a section of slicer visuals having slicers of selecting Month, Country, Product and Category and a section of a card visual and table visual. The card visual and the table visual gives garbage values when I select multiple values in the slicer visuals. How can I use DAX and show a message on the place of the card and table visual showcasing to select a single value and when a single value is selected the values are displayed.

HI, @Anonymous 

use has HASONEFILTER()  this give you ability to select one value and give output in boolean value(true, false)

you can use IF() function  to implement your requirnment
like 

result = 
switch(true(),
    HASONEFILTER('tablename'[country]), your expression,

     HASONEFILTER('tablename'[month]),your expression,

    HASONEFILTER('tablename'[product]), your expression,

    HASONEFILTER('tablename'[category]), your expression,

    "select a single value")

here your expression means your calculation part
