In this discussion, a solution is suggested by referral to the name of an IFRAME as “IFRAME_name“.
I’d like to know how I’m supposed to obtain that name in my CRM.
EDIT: The component I’m talking about looks like an IFRAME but is, in fact, a web resource (a HTML document inside CRM, i.e. not an external page). When I refer from it to CRM stuff, I go
parent.window.Xrm.Page + the usuals
but how can i refer from the CRM down to that component?
When you create the IFrame on the form you set a name.
Open the form customisations and read the name from there.
