DAX: How to do ALLSELECTEDEXCEPT()?

Title says it all really. I'd like to combine the behaviours of ALLEXCEPT and ALLSELECTED. So remove the filters, other than external filters, from all the columns except a particular one. Is there a function or way to combine these functions?
 

Excel Facts

Select a hidden cell
Somehide hide payroll data in column G? Press F5. Type G1. Enter. Look in formula bar while you arrow down through G.
Hi again,

A combination of ALLSELECTED & FILTERS should give you the ALLSELECTEDEXCEPT behaviour:

Code:
=
CALCULATE (
    [YourMeasure],
[COLOR=#ff0000][B]    ALLSELECTED ( YourTable ),[/B][/COLOR]
[COLOR=#ff0000][B]    FILTERS ( YourTable[ColumnToKeep] )[/B][/COLOR]
)

The logic is basically use ALLSELECTED on the entire table, then bring back the explicit filters on the column you want to keep.
And we know that FILTERS ( YourTable[ColumnToKeep] ) will be more restrictive than the values of ColumnToKeep that exist in ALLSELECTED ( YourTable ), so we can safely intersect these two filter arguments.

Note that I used FILTERS rather than VALUES. FILTERS returns a column of values explicitly filtered on a column, whereas VALUES would return values that exist in the current context as a result of both explicit filters and cross-filtering.

Does this give you the behaviour you were looking for?

Yep, that does it. Thanks again.

I thought I was starting to have seen, if not be able to use, all the main DAX functions, but FILTERS is new to me. I think I understand your formula to be doing the intersect of the ALLSELECTED and FILTERS, but they are calculated independently before being applied.

I'm sure there are other things I will have struggled with before that FILTERS would have helped with.

Just wanted to say thanks for the solution, and thanks to the OP for phrasing it in exactly the way I googled it! :)
