RE: [development-axapta] Re: Formbuilddatasource - adding a datasource runtime to an already running form

Hi Manfred,


Thanks for your reply. Do you know how to add a formdatasource at
runtime? I can't find any ways to do it myself. However, I still think
it must be a formbuilddatasource because e.g. formbuildcontrol's can be
added at runtime - but not a formbuilddatasource. I suspect it's a bug
in Axapta.


Best regards,

Hi Lars,

I think the problem is the FormBuildDatasource. A FormBuildDatasource is
used in Designer, in Morphx, before the form is build.
At runtime you have to use a FormDatasource.

Try it, perhaps it helps
