ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Desktop.Mapping.Controls Namespace / TransformationInfo Class / SpatialFilter Property
Version

SpatialFilter Property (TransformationInfo)
Gets and sets the spatial filter. If specified, the SpatialFilter will be used to filter the available transformations for the given source and target spatial reference (which can initially not be defined).
Syntax
public Envelope SpatialFilter {get; set;}
Remarks
This is optional. The spatial filter can be defined in any spatial reference. It will be projected to the source spatial reference if needed. This property will override any SpatialFilter defined on the TransformationsControlProperties object. If no spatial filter is set on both the TransformationInfo object and the TransformationsControlProperties object, all the possible transformations for a given source and target coordinate system pair will be returned.
Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.1 or higher.
