This is a lighting fixture family file. How can I uncheck "HOST" using API?

Thanks!

Dear Kukuzry,

I am guessing here...

Is this what you are after?

  /// <summary>
  /// Hide the LightingFixtures category 
  /// Hosts subcategory in the given view.
  /// </summary>
  void HideLightingFixtureHosts( View view )
  {
    Document doc = view.Document;

    Categories categories = doc.Settings.Categories;

    Category catLightingFixtures 
      = categories.get_Item( 
        BuiltInCategory.OST_LightingFixtures );

    CategoryNameMap subcats 
      = catLightingFixtures.SubCategories;

    Category catHosts = subcats.get_Item( "Hosts" );

    view.SetVisibility( catHosts, false );
  }

Cheers,

Jeremy

Dear Kukuzry,

Well thank God we finally got that one nailed down.

I added the method implementation to The Building Coder samples:
