Entity A has related Entity B's, and Entity A has a "Quick View" embedded in a form in Entity B.
I have some logic that I'd like to run from the related Entity B based on field values from Entity A contained in the quick view, and rather than use REST to query the value in A, I thought using an embedded "Quick View" from entity A on the form in Entity B to bring the field whose value I could simply read from the quick view without having to perform a REST call to Entity A.
Unfortunately I haven't found a supported way to do this as it appears the quick view form is inaccessible through Xrm.Page.
Am I forced to use a REST or Fetch call to the parent entity?
