Determine Document State ? DisplayedInUI : InBackground

[lwlXUTTT]

Dear Community,

Is there any fast/clean method to determine whether the document has been opened and activated in UI oraz just runs in the background?

I used to check it this way:

doc.ActiveView != null

but I was wondering if there is any better way,

any help much appreciated

The approach you describe is exactly what came to mind. If it works, it sounds like a good one to me.

Hi Lukasz, were you successful on your approach? I'm trying to do the same but via the Revit Lookup I found that only the active document has a not null active view. Thank you.

Hi @floretti ,

I was not aware of that...

But then another solution that comes to my mind is:

if list of ViewIds > 0 then

Document is opened and activated

please let me know whether it works for you,

Best, Lukasz

I tried but in order to get the OpenUIViews you need to loop through each document making it active in the UI.

ActiveUIDocument.GetOpenUIViews();

After some research I found out that there are (still) no native ways to activate open documents (refer to this article) and the effort won't outweigh the benefits I'll get from this so I'm dropping it.
