How to get temporarily hidden categories?

[AndrewButenko]

Hello. I have a problem. I need to check the category for visibility. I use GetCategoryHidden but it does not  work for temporarily hidden categories. 

Any ideas how to do this?  Thanks.

hi,

i believe it needs to be inside an ICollection

hideCategoriesTemporary(Icollection <ElementId>)

where ElementId is the list of your Categories ID

ex:

col = List[ElementId]()
    for i in comments:
        col.Add(i)
    View.HideElementsTemporary(col)

The method View. IsElementVisibleInTemporaryViewMode() checks for visibility given a specific TemporaryViewMode.

View v = doc.ActiveView;
ElementId catid = new ElementId(BuiltInCategory.OST_Doors);
bool isVisible =  v.IsElementVisibleInTemporaryViewMode(TemporaryViewMode.TemporaryHideIsolate,catid);
