Negation in filter expression

[Administrator]

I try to apply a row-filter on a gridGroupingControl. e.g. a filter for name of persons.

to show all rows where column "name" has the value ''Klaus'' I use following expression:
[name] LIKE ''Klaus''
and that works fine ;-)

but now I want to show all rows where "name" has a different value from ''Klaus''. But i can''t find how to use a NOT in the expression. Following does not work:
NOT ([name] LIKE ''Klaus'')

Also in the documentation "NOT" is not listed as operator in filter expressions.

Can anyone give me a hint how to negate the expression of RecordFilterDescriptor?

Thx, Klaus

OK - I found it by myself ;-)

"([name] LIKE ''Klaus'') = 0"

works fine!
