Parameter Description Example value

Expression The expression to evaluate.

Result

Returns OK or error.

Description

Sorts a list with using an expression to evaluate.
The expression is run every time two values are compared, so keep it quick. It should return 1 if leftValue is smaller than rightValue.

Our normal List.Sort is faster due to not having the overhead of evaluating expressions.

Examples

Sort numbers numeric with GetAsNumber() function:

MBS("List.SortWithEvaluate"; "1¶22¶3"; "GetAsNumber(leftValue) < GetAsNumber(rightValue)")

Example result:
1
3
22

Sort dates with using GetAsDate:

MBS("List.SortWithEvaluate"; "1/1/2000¶2/22/2020¶3/4/1998"; "GetAsDate(leftValue) < GetAsDate(rightValue)")
