Slicer to show selected value AND blank values

[vanya_val]

Hi all,

I have a slicer in my data with the following options:

   (Blank)

   Option 1

   Option 2

   Option 3

When a user selects any of the options 1-3, I want the result to always display both the selected value and blank values as well. 

Is there a way to achieve this through DAX? 

Any help is much appreciated!!

Hi @vanya_val ,

Does it make sense? If yes, please accept it as solution. More people will benefit here.

@v-xuding-msft  Thank you for this. The solution you linked looks perfect for my problem but for some reason I can't make it work! It's probably something in my model, I'll do a bit more testing and post an update.

Hi @vanya_val ,

Please reference the similar thread: Always select Blank in the Filter  to have a try.

@vanya_val , Make sure these option are part of separate table/dim

Try new measure

Measure =
var _sel = selectedvalue(Dim[Dim1])
return
calculate(Sum(Table[Value]),filter(All(Dim),Dim[Dim1] =_sel || isblank(Dim[Dim1])))

Or

Measure =
var _sel = allselected(Dim[Dim1])
return
calculate(Sum(Table[Value]),filter(All(Dim),Dim[Dim1] in _sel || isblank(Dim[Dim1])))

Thanks very much @amitchandak for your reply.

I'm afraid I'm not sure how to apply the measure you suggested to the slicer, maybe I'm doing something wrong. Rather than summing the values, I am looking to filter a table visual with the slicer.

For example, I have a table visual showing a list of Products and their Colour. The Colour could be Red, Blue, Green or (Blank). When I select Green on the slicer I want the table visual to be filtered to show all products with colour Green or (Blank). But rather than summing up a value related to those products I just need to see a list of them. It sounds like I need a measure to say whether something is selected or blank, but I'm not sure how to write that in DAX.

@vanya_val  If you want to create a measure to check if something is selected or not. You can create a calculated measure like below

Selected_Yes_No = IF(HASONEFILTER(Color_Tab[Color]), "Selected Yes", "Nothing selected")

If you want to achieve something else, please let us know
