expansion record callback

[claudiobosticco]

Hello, is it available a callback or a method to observe to know when a user expand or collapse a record?

[claudiobosticco]

In my use case, I've got a custom expansion component, with custom controls for editing (and others widgets), and canExpandMultipleRecords is false.
When a record collapses with unsaved changes, I want to ask the user (there's also a save button) if she/he wants to save or not, so I need to know if the record is collapses, both because the user tries to expand another record, and also because the user tries to collapse the same record.Seems

Note to self: ListGrid.collapseRecord, it's simple as that.
Sorry for the naivety.
