Exceptions
ExceptionCondition
ArgumentException When setting this property: The hostId is not a valid railing host.
ArgumentNullException When setting this property: A non-optional argument was null
Remarks
If the host will be a Stairs in MultistoryStairs element, use [M:Autodesk.Revit.DB.Architecture.Railing.SetMultistoryStairsPlacementLevels(System.Collections.Generic.ISet`1{Autodesk.Revit.DB.ElementId})] to set the base levels of the stairs where the railing should be placed.

If %hostId% is the id of a Stairs Component (Run or Landing), it means that the Railing will be hosted by the Stairs element but railing adjustment to the stairs will start from the Component. If a stairs id is set as a host, the lowest stairs component below or above the railing sketch will be chosen as the host instead.
