How to hide a TppLabel depending on a DataPipeLine's Field Value

rbuser

Hi,

I need to hide a?label in a report if a DataPipeLine's Field Value (Date)
is NULL. My first attempt was a code like this:
lblAnul.Visible:= lInvoice['DATE_ANUL'] <> Null;
but it didn't work...

The label is at the Title band of the report and the code bellow is in
the title's AfterGenerate event procedure. I'm using RB 7.02...

If any of you have a suggestion I would be very pleased.

Regards,
Elio.

Tech Tip: RAP: Checking for Null Data values
----------------------------------------------

The DataPipeline.FieldObjects[] array property provides access to the
TppField objects. TppField has an IsNull boolean property.

The notation is DataPipeline.FieldObjects['FieldName'].IsNull

example:

if Customer.FieldObjects['Addr1'].IsNull then
ShowMessage('field value is null');
