Exhaustive listing of BuiltinParameter in a BuiltinParameterGroup

[Anonymous]

HI,

Is there a way to get all the possible BuiltInParameter inside a BuiltinParameterGroup?
I found this post : http://spiderinnet.typepad.com/blog/2011/04/parameter-of-revit-api-6-builtinparametergroup.html but the given algorithm depends on the current model. So it's not efficient and I would be missing data.

Regards,

Dear DA ROCHA Romain,

I am sorry to say that there is currently no API access to this functionality. 

Because "Parameter groups are used to sort parameters within the Element Properties dialog."

It is element level information.

Its value depends on element, different element will return different values.

Hi!

Dear JimJia, does it really mean, that some specific builtinparameter could be in one builtinparameter in the first element and in the other in second? It is interesting

That behavior would be a little bit weird

I'll Believe it when I see it. Which I am assuming will be years from now as usual.

Here's an idea in the off chance you are actually working on improving the program:

The shared parameter interface and usability needs to be completely revamped perhaps a whole different interface or even separate linked database program that can properly manage large numbers of Shared parameters (and don't give the bogus excuse that their are third party programs that fill this need. Most of the third party programs out there are at best useless and at worst broken)

@mtwilliams416, I agree that shared parameters could use work. Hopefully we can add them to our roadmap going forward. In the meantime, I recommend voting on this and this idea.

Cheers,

Jeremy

You can use a filtered elementcollector to get all the BuiltinParameters in a document.

			StringBuilder sb = new StringBuilder();
			Document document = this.ActiveUIDocument.Document;
			IEnumerable<ParameterElement> builtinParams = new FilteredElementCollector(document)
				.OfClass(typeof(ParameterElement))
				.Cast<ParameterElement>()
				.Where( p =>  !(p is SharedParameterElement));
			foreach(ParameterElement pElem in builtinParams)
			{
				sb.AppendLine(string.Format("{0} {1}", pElem.GetDefinition().ParameterGroup,pElem.GetDefinition().Name));
			}
			TaskDialog.Show("debug",sb.ToString());

disregard my answer. I wasn't thinking straight. the test in the Where clause is totally wrong.
