I want to:

  1. create new data frame,
  2. give it a name,
  3. activate it and then fill with layers, etc. in ArcMap .NET custom command.

With this code I achieve 1. and 2., but don't know how to activate it:

// mxDocument is IMxDocument
IMap newMap = mxDocument.Maps.Create();
newMap.Name = "I can name it as I want: " + Guid.NewGuid();
//HOW TO Activate newMap???

New data frame is created, added to TOC but how to make it active?

mxDocument.ActiveView.FocusMap = newMap

gives System.NotImplementedException.

EDIT: IMaps.Create() + IMaps.Add() is too primitive way to create a data frame, it won't work properly. See this link for a better description.

Try setting ActiveView (rather than FocusMap) to newMap:

mxDocument.ActiveView = newMap
  • Thanks, it worked (with a cast): mxDocument.ActiveView = (IActiveView)newMap. – Remigijus Pankevičius Feb 11 '15 at 17:00
