expression - avoid grouping on empty values RDLC -

i have column grouping on datafield. need grouping when there value in field. right groups on null field too.

i have tried next grouping expressin:

=fields!scalename.value <> "" or fields!scalename.value <> nil

you can resolve problem using grouping filter (right click on grouping > group properties > filters):

expression: =isnothing(fields!scalename.value) type: boolean operator: = value: =false
