How to change Revit 2014 element name by API C#

[ggarnik]

Hi everyone

I want to change element name by API and I have the following code.

Reference r = docUI.Selection.PickObject(ObjectType.Element, "Please pick an element");
Element element = doc.GetElement(r.ElementId);

element.Name = "MyElement";

But why occured this error ? 'This element does not support assignment of a user-specified name.' 

Or should I change the name by another way ?

Please help!
