Parameters
- mode
- value
Sets the state of a single SnapMode.
// set only Point and Edge snapping modes, clear everything else //At 2.x - ArcGIS.Desktop.Mapping.Snapping.SetSnapModes(SnapMode.Point, SnapMode.Edge); ArcGIS.Desktop.Mapping.Snapping.SetSnapModes( new List<SnapMode>() { SnapMode.Point, SnapMode.Edge }); // clear all snap modes //At 2.x - ArcGIS.Desktop.Mapping.Snapping.SetSnapModes(); ArcGIS.Desktop.Mapping.Snapping.SetSnapModes(null); // set snap modes one at a time ArcGIS.Desktop.Mapping.Snapping.SetSnapMode(SnapMode.Edge, true); ArcGIS.Desktop.Mapping.Snapping.SetSnapMode(SnapMode.End, true); ArcGIS.Desktop.Mapping.Snapping.SetSnapMode(SnapMode.Intersection, true); // get current snap modes var snapModes = ArcGIS.Desktop.Mapping.Snapping.SnapModes; // get state of a specific snap mode bool isOn = ArcGIS.Desktop.Mapping.Snapping.GetSnapMode(SnapMode.Vertex);
// interested in only snapping to the vertices of a specific layer of interest and not the vertices of other layers // all other snapModes should be off. // snapping must be on ArcGIS.Desktop.Mapping.Snapping.IsEnabled = true; // turn all application snapModes off //At 2.x - ArcGIS.Desktop.Mapping.Snapping.SetSnapModes(); ArcGIS.Desktop.Mapping.Snapping.SetSnapModes(null); // set application snapMode vertex on ArcGIS.Desktop.Mapping.Snapping.SetSnapMode(SnapMode.Vertex, true); // ensure layer snapping is on await QueuedTask.Run(() => { fLayer.SetSnappable(true); }); // set vertex snapping only var vertexOnly = new LayerSnapModes(false) { Vertex = true }; // set vertex only for the specific layer, clearing all others var dict = new Dictionary<Layer, LayerSnapModes>(); dict.Add(fLayer, vertexOnly); ArcGIS.Desktop.Mapping.Snapping.SetLayerSnapModes(dict, true); // true = reset other layers
