Hi All,

I'd like to display different fields/columns in a graph based on a parameter.
If the parameter is Null I need to display this field: Fields!vchParentIncidentType.Value and if its not null i need to diaplay this field:Fields!vchIncidentType.Value
I'm using the expression below but at the moment its just displaying this field: vchIncidentType.Value - even if there's no value supplied for the parameter(NULL)

=IIF(ISNothing(Parameters!uidIncidentTypeId.Value), Fields!vchParentIncidentType.Value, Fields!vchIncidentType.Value)

Please help with the correct expression to use.

Kind Regards
Teee

Hi,
Multi-valued parameters can't be NULL as far as I know, no value supplied gives a parameter value of blank rather than NULL.
Try this expression:

=iif(Join(Parameters!uidIncidentTypeId.Value) = "", Fields!vchParentIncidentType.Value, Fields!vchIncidentType.Value)

Cheers
Gaz
