How to set a conditional requirement depending on choice, e.g. radiobutton or checkbox

[Władysław Czaja]

Hi all, 

How to make a section or control required when it is visible after selecting a radiobutton / checkbox, and how to make a required section or control disappear when the section / control is not visible?

And besides  - How to set in grid / repeated grid, If one field in the line is filled (no matter what), fill in the others (then they should be required)

You cannot make sections required; only fields can be required. So you could
make every field required, without the condition, and if that field is not
visible, then the "required" constraint won't apply (as users wouldn't have
a way to provide a value if the field is not visible). And you'll let me
know if I somehow misunderstood your question (if so, maybe an example would
help).

Say you have controls `a`, `b`, `c`, then for `a` you would say that it is
required if: `xxf:non-blank($b) or `xxf:non-blank($c)`. And you write a
similar expression for controls `b` and `c`.

Hi Vlad, if you got a chance to work on this one, have you managed to what
you were looking for with required/visible fields, maybe based on the
suggestion in my previous message?
