Event when user closes a view

[DanielKP2Z9V]

Is there any way to run code when user closes a UIView? I've looked at DocumentChanged event, but neither Modified nor Deleted elements include UIViews. There is ViewActivated Event, but I don't see corresponding "ViewDeactivated Event".

This is necessary to keep track of currently opened UIViews, as output of GetOpenUIViews doesn't include sheets with activated views.

Yes, indeed. You need some creative ideas to address this. It can help to search for existing answers here in the forum:

I've ended up writing custom function to close current view and close selected views. However, if user won't use them scripts will go out of sync. I thought about it for a long time, but there doesn't seem to be any way in Revit API to detect if user closes a view via Revit interface?
