access keynote in API

[SamWilson]

Hi, this is a beginner's question I guess. I am trying to access an elementtype's keynote parameter. I use the following code:

Element elem = doc.GetElement(pickedRef);
ElementType eType = doc.GetElement(elem.GetTypeId()) as ElementType;

Parameter paraUniCode = eType.get_Parameter(BuiltInParameter.UNIFORMAT_CODE);
Parameter paraKeynote = eType.get_Parameter(BuiltInParameter.KEY_VALUE);

then the assembly code gave me the right result, but the keynote is NULL.

I have assigned an assembly code and an element keynote to the element type in my model.

Where did I do wrong?

Thank you in advance!

It looks to me like: BuiltInParameter.KEY_VALUE belongs to the Keynote Tag.

The Keynote of the element type should be:

Parameter paraKeynote = eType.get_Parameter(BuiltInParameter.KEYNOTE_PARAM);
