Re: Filter Legend from viewsheet?

I'm uisng your workaround to filter all the legends placed on sheets and then delete the ones that are not on shets

            //get all the sheets in the model
            FilteredElementCollector vftCollector = new FilteredElementCollector(doc);
            vftCollector.OfClass(typeof(ViewSheet));            

            //get all the Legends in the model
            FilteredElementCollector legCollector = new FilteredElementCollector(doc)
               .OfClass(typeof(View));

            List<ElementId> allLegendsOnModelIdlist  = new List<ElementId>();

            foreach (ElementId eid in legCollector.ToElementIds())
            {
                View v = doc.GetElement(eid) as View;
                if (v.ViewType == ViewType.Legend)
                    allLegendsOnModelIdlist.Add(v.Id);

            }


            List<ElementId> allsLegendsOnsheetsId = new List<ElementId>();

            foreach (ViewSheet vs in vftCollector)
            {

                //get all legends on sheet
                foreach (ElementId eid in vs.GetAllPlacedViews())
                {
                    View v = doc.GetElement(eid) as View;

                    if (v.ViewType == ViewType.Legend)
                        allsLegendsOnsheetsId.Add(v.Id);
                        //TaskDialog.Show("Legend", "Found a legend named: " + v.Name + "\non sheet: " + vs.LookupParameter("Sheet Number").AsString());
                }
            }


            var legendsToDelete = allLegendsOnModelIdlist.Except(allsLegendsOnsheetsId);

            toDelete.AddRange(legendsToDelete);
