I'm trying to add a custom property to a WebPart to select multiple terms from a TermSet in SharePoint 2013.
I have found this article: http://msdn.microsoft.com/en-us/library/dd584178(v=office.11).aspx
This, however, is tagged for SharePoint 2003.
Then I found this: http://www.dhirajranka.com/?p=420 which is for SharePoint 2010. But it doesn't seem to work either. I can't override the method
GetToolParts() cause there seems to be none in the WebPart class.
So now I'm back at the start and I don't know where to begin. I don't have any idea left now. Maybe someone can point me into a direction? I would really appreciate it.
