How to disable selecting old dates on a date slicer?

[wpf_]

I have a calendar table which uses calendarauto() and gives me just the dates for the year and use it in a slicer as a date picker.  I am using the calendar picker not the slider or drop down picker.  How can i disable the user from picking dates older then today?  in my calendar table i have a column that only shows dates from today onward.  Older dates show up blank.  And i am using this column in the slicer.  However when i pick an older date, the slicer still shows the older date even though the data is today's date (min).  So this could confuse users.  I am trying to avoid using a slider or drop down.  Thanks.

Hi @wpf_ 

If you only want to show dates after today in your date slicer, you can try to build a filter measure.

I build a Date table by calendar function.

Date = 
CALENDAR(DATE(2021,01,01),DATE(2021,12,31))

Measure:

Slicer Filter Measure = IF(MAX('Date'[Date])<TODAY(),0,1)

Add this measure into your slicer and set it to show items when the value equal to 1.

@wpf_ , if you are using calendar date picker, between range?

I think that is able to show dates in the past even if they are not available.

Is there any way to get around this?  Even if i just want to display a messsage that they can't show it?
