    Hi powerbiexpert22 

    There is no native option to force a slicer selection at the whole report/page level and automatically block all visuals from showing data. A common workaround is to handle this at the individual visual level.

    You can create a measure that checks whether the slicer field is filtered:

    Filtered check =
    IF (
    ISFILTERED ( 'Vehicle'[Model Year] ),
    1,
    0
    )

    Then add this measure to the visual-level filters of each visual that should be hidden, and set the filter to show only when Filtered check is 1.

    Also, if you do not want users to view the report by selecting all values, you should turn off the "Select all" option in the slicer.

    I would also recommend adding a clear instruction for the user, for example by using a dynamic title, card, or text message:

    User Instructions =
    IF (
    [Filtered check] = 1,
    "Regular title",
    "Please select at least one vehicle model year to view the report"
    )
    For reference you can refer to my example with city

    Step 1) Create a guard measure:

    Selection Guard =
IF (
    ISFILTERED ( 'Table'[ModelYear] ),
    1
)

    Step 2) Add this measure as a visual-level filter on every visual in the page, set to is equal to 1. Visuals will be blank until the user makes a selection.

     

    Step 3) Create a warning Card using:

    Warning Message =
IF (
    NOT ISFILTERED ( 'Table'[ModelYear] ),
    "Please select a Model Year to view the report."
)

    Place this Card prominently on the page. It disappears automatically once the user selects a value.

    Create this measure and add it as a visual-level filter (is not blank) on every visual in the page:

    Selection Guard =
IF (
    ISFILTERED ( 'Table'[ModelYear] ),
    1
)

    Set a visual-level filter on each visual: Selection Guard is 1. When nothing is selected in the slicer, ISFILTERED returns FALSE, the measure returns BLANK, and the visual disappears entirely.

        Not in a meaningful way. What-if parameters in Power BI generate a numeric or predefined-list slicer, not a filter that drives ISFILTERED on a real data column. So you cannot replicate this behavior using parameters.

        Hi powerbiexpert22,
        This requirement cannot be achieved directly using Parameters in Power BI. Parameters are mainly used for scenarios like What-If analysis, dynamic field selection, or changing measures/columns dynamically.

        For enforcing mandatory slicer selection before showing report data, the recommended approach is to use a DAX measure with ISFILTERED()  and apply it as a visual-level filter, as suggested above.

        This is currently the most common and supported workaround in Power BI for this type of requirement.
