Rowcount with Field Parameter

[hi5jimmy]

Hi Power BI Experts,

I am currently using below formula to count the row in table visual which is working fine. However, I want to use filed parameter to select columns dynamically in table visual could you help me how can I transform below formula. Result should display the rowcount no metter what combination user select in field parameter slicer. 

Table 1:

Column 1	Column 2	Column 3	Column 4 (used for measure)

Measure 1 = Sum(Column 4)

Formula to calculate rowcount:

COUNTROWS(GROUPBY(Table 1, Table 1 [Column 1], Table 1 [Column 2], Table 1 [Column 3], "Name", sumx(currentgroup(), Table 1 [Measure 1])))

Thanks in advance.

@hi5jimmy Try if this measure works for you:

RowCountMeasure =
VAR SelectedColumns =
    VALUES('FieldParameterSlicer'[SelectedColumn])
VAR GroupedTable =
    SUMMARIZE(
        'Table 1',
        SelectedColumns,
        "RowCount", COUNTROWS('Table 1')
    )
RETURN
    COUNTROWS(GroupedTable)

If you find this insightful, please provide a Kudo and accept this as a solution.

Hi @devesh_gupta ,

This is resulting in total rowcount of table as below step gives all columns not selected ones.

VALUES('FieldParameterSlicer'[SelectedColumn])

Hi @devesh_gupta ,

Thanks for your inputs. however, Summarize function is not allowing me to use parameters in second argument. It says Summarize function expects a column name as argument number 2.

@hi5jimmy Okay, let's try like this:

RowCountMeasure =
VAR SelectedColumns =
    VALUES('FieldParameterSlicer'[SelectedColumn])
VAR GroupedTable =
    CALCULATETABLE(
        'Table 1',
        'FieldParameterSlicer',
        'FieldParameterSlicer'[SelectedColumn] IN SelectedColumns
    )
RETURN
    COUNTROWS(GroupedTable)
