HostId Property

The host of the railing.

Namespace: Autodesk.Revit.DB.Architecture
Assembly: RevitAPI (in RevitAPI.dll) Version: 24.0.0.0 (24.0.0.0)
Since:  2013

Syntax

C#
public ElementId HostId { get; set; }
Visual Basic
Public Property HostId As ElementId
	Get
	Set
Visual C++
public:
property ElementId^ HostId {
	ElementId^ get ();
	void set (ElementId^ value);
}

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.
