master/detail relationship

rbuser

Hi, it's me again. I have got another problem. I have to define a
master/detail relationship dynamically at run time.
I tried the Tech-tip from Nard Moseley from 07.01.2002 , but in the end I
didn't succeed. Is there a different way
to do that?
Thanks in advance
Andreas

There are a number of different ways of creating master-detail relationship.
They include:

a) Linking at the data source level - Place two table or query objects and
two data source objects on the form and connect them respectively. Set the
MasterSource property of the detail table to the data source of the master
table and set the master fields to create a link.

b) Linking at the data pipeline level - Attach a data pipeline to each data
source in the setup from a). Set the MasterDataPipeline of the detail
pipeline to the master pipeline and set the MasterFieldLinks to create a
link.

c) Linking in DADE - Create two dataviews, one for the master qeuery and one
for the detail query. Drag the field you would like to link on from the
detail data view to the master data view. That will create a visual link
between the data views.

See demos 71-80 in the RBuilder/Demos/Reports directory.

You can apply the same techniques at design and at runtime.
