Re: [Dynapi-Help] 3x api and text boxes - semi solved

[<ml...@id...>]

My app is an editor for a complex dataset.

Basically it presents a list box of choices, on selection of choices,
a set of listboxes and user inputs pop into existance to the right,
for the various sub choices that are available given that selection

Since the available options are driven by the choices the user makes,
the select and text boxes come and go as the user interacts with the
system.

This is driven out of an xml file which defines the choice space.
The forms are never submitted as such, instead the data is read out
and the main display is updated. That display gets submitted back to
the host.

I will have to make the application modal.
