View Schedule with Detail Numbers Macro for Revit

A question was posted on http://revitforum.org about showing a view's detail number in a view list schedule. Revit has a parameter for the Detail Number (see first image) but it isn't accessible to add in a view list schedule.

Solution

Step 1
Create a View List schedule (or edit an existing one) and add a new text Parameter named "Detail_Number" (notice the _ in the name)

Step 2
Create a new macro with the following routine and run it

public void DetailNumber()
{
    UIDocument uidoc = this.ActiveUIDocument;
    Document doc = uidoc.Document;
  
    string strDetailNumber = "Detail_Number";         
  
    FilteredElementCollector collector = new FilteredElementCollector(doc);
    ICollection<Element> collection = collector.OfClass(typeof(View)).ToElements();
  
    using (Transaction t = new Transaction(doc, "Detail Number"))
    {
        t.Start();
      
        foreach(Element e in collection)
        {
            View v = e as View;
          
            try
            {
                Parameter bpDetailNumber = v.get_Parameter(BuiltInParameter.VIEWPORT_DETAIL_NUMBER);
                v.get_Parameter(strDetailNumber).Set(bpDetailNumber.AsString());
            }
            catch
            {
              
            }
          
        }
      
        t.Commit();
    }
}

Results
All the views that are on sheets now have the Detail Number copied into the Detail_Number parameter.

Run the macro whenever you want to update the values in the new parameter to reflect the current state of the project (aka is doesn't auto update and needs to be run manually).
