The ITopologyGraph::Select method allow to modify the current set of selected TopologyElement part of the TopologyGraph. The selection behavior is determined by the esriTopologySelectionResultEnum parameter.


If a Topology Element selected programmatically has to be moved using the Topology Edit Tool, the Selection Anchor has to be set to a valid location on the topology element.


For example, to move a node the selection anchor can be set to the location of the node.

ESRI.ArcGIS.Display.IAnchorPoint anchorPoint = editor.SelectionAnchor;
anchorPoint.MoveTo(topologyNode.Geometry, activeDisplay);
