COUNT ROWS WHERE VALUE IN ONE COLUMN, HAS A SPECIFIED STRING IN ANOTHER COLUMN

[rockingmark]

Trying to count rows in a table and give a measure for how many rows contain the string "Very" in the Description column for each Colour.  Everything I have tried counts the number of rows that have very in the whole table (in this case 6), so the third column in my table is incorrect. The third column used the calculated column:-

COUNTIF COLOUR FOR Very =

COUNTROWS(

    FILTER(

        ALL(Brightness),

        Brightness[Colour] = Brightness[Colour] &&

        CONTAINSSTRING(Brightness[Description ],"Very") = TRUE()

    )

)

The last column " Count of "Very" for each colour" is the desired output, which is a count of the number of rows containing "Very" for each colour

Colour	Description	COUNTIF COLOUR FOR Very	Confirmed	Count of "Very" for each colour
Blue	Very Dim	6	Yes	1
Blue	Dim	6		1
Blue	Bright	6		1
Blue	Slightly Dull	6		1
Green	Very Bright	6		2
Green	Very Dim	6		2
Green	Dim	6	Yes	2
Green	Bright	6		2
Green	Slightly Dull	6		2
Red	Very Bright	6		3
Red	Very Dim	6		3
Red	Dim	6	Yes	3
Red	Bright	6		3
Red	Slightly Very Dull	6		3

Thank you for your prompt reply! @parry2k 

Hi @rockingmark 

Please try the following measure:

Measure = 
VAR _color = SELECTEDVALUE(Brightness[Colour])
RETURN
CALCULATE(COUNTROWS('Brightness'),FILTER(ALL('Brightness'),'Brightness'[Colour]=_color && CONTAINSSTRING('Brightness'[Description],"Very")=TRUE()))

This is the result you want:

@rockingmark if you want to show the count for each row of the color then do this:

Very = 
VAR __Color = Color[Colour]
RETURN
CALCULATE ( 
    COUNTROWS ( Color ), 
    FILTER ( 
        ALL ( Color[Colour], Color[Description ] ), 
        Color[Colour] = __Color && 
        CONTAINSSTRING ( Color[Description ], "Very" ) 
    ) 
)

Hi parry2k,
Thanks for this solution. I used it to make a new column (hope that was the intention)
This solution resulted in rows with blank values as shown below. Couldn't understand why, especially as some of the rows that dont have the word "Very" in the description got a count result in the "Very" column and some didnt'.
Could you explain why it worked that way, to help my understanding of dax

I would like all rows for very column very to be populated.

@rockingmark try this, change the column and table name as per your model

Very = 
VAR __Color = Color[Colour]
RETURN
CALCULATE ( COUNTROWS ( Color ), FILTER ( ALL ( Color[Colour] ), Color[Colour] = __Color && CONTAINSSTRING ( Color[Description ], "Very" ) ) )
