Hi Drew, I tried you suggestions, but to no avail. I think I need to still do .Modify(insp) first and then the .Execute. I tried moving the .Execute up to right after the .Modify. That works for the first pass, but then on the second pass it craps out at the .Modify. I think running .Execute might dispose of the EditOperation object??

Hi, With a selection of features from the same layer in ArcMap, a user clicks on a tool that autopopulates some fields based on some spatial queries. There is a loop to handle when more than one feature is selected. Before the loop starts I do this: ar editOperation = new ArcGIS.Desktop.Editing.EditOperation(); editOperation.Name = "Create new Facility IDs"; var insp = new ArcGIS.Desktop.Editing.Attributes.Inspector(); //create the Inspector Then I loop through the code and do what needs to be done. The current selected feature has an attribute that the next selected feature will need to use (ie. to increment it's number by 1), so I do this to save the current features edits: editOperation.Modify(insp); If I step through my code, up to this point everything is fine and attributes seem to be getting updated. With the next selected feature I will then loop through the code again, but this time my code that looks at the field that needs to increment by one doesn't 'see' the edit made the first time through, so the counter ends up being the same as the previous edit. At the end of the looping, I do this: editOperation.Execute(); If I select features one at a time and run things, all is good. It's only when doing multiple selections. Is editOperation.Modify the right method to call and get things saved to the database?? If I run .Modify and .Execute right after the other, then I get a Null Reference the next time I go through the loop....I guess that means I need to recreate the EditOperation each time through, which I don't want to do. Any ideas on where I am going wrong??

Ah yes, that makes sense to me now. Thanks for helping!!

Hi, I'm trying to do a spatial query on a layer in my map. In my code, I first check to see if the layer is there: IEnumerable<Layer> gridLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_Grid", StringComparison.CurrentCultureIgnoreCase) >= 0); if (gridLayer.Count() == 0) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Please add the GRID layer before proceeding.", "Missing Layer"); return; } Later in the code I want to use a point to intersect the gridLayer using this code: SpatialQueryFilter spatialFilter = new SpatialQueryFilter(); spatialFilter.FilterGeometry = intersectPoint; spatialFilter.SpatialRelationship = SpatialRelationship.Intersects; spatialFilter.SubFields = "GRIDNO"; FeatureLayer grid = (FeatureLayer)gridLayer; //This does not work. Null Reference Exception or sometimes an InvalidCast, depending on what I am doing. How do I turn my gridLayer from above into something I can use to query?? I've tried many different things...FeatureLayer, BasicFeatureLayer, FeatureClass.....nothing works. RowCursor gridCursor = grid.Search(spatialFilter); while (gridCursor.MoveNext()) { using (Feature feature = (Feature)gridCursor.Current) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(feature[0].ToString()); } }

Hi Sean, Yes, I eventually found a sample that broke my line down into segments, but I like your solution much better. Two lines of code is always better than 10, especially when all I need is the first point. This is what I had: Polyline theLine = insp.Shape as Polyline; ReadOnlyPartCollection polylineParts = theLine.Parts; IEnumerator<ReadOnlySegmentCollection> segments = polylineParts.GetEnumerator(); segments.MoveNext(); ReadOnlySegmentCollection seg = segments.Current; foreach (Segment s in seg) { intersectPoint = s.StartPoint; break; //to get just the first point } Thanks for your help!! This is what I ultimately went with: var pointCollection = ((Multipart)insp.Shape).Points; MapPoint thePoint = pointCollection[0];

Hi, I'm trying to get the StartPoint of a selected Polyline. So far, this is what I have: I use an Inspector to get each selected feature, like this: var selection = currentLayer.GetSelection(); IReadOnlyList<long> selectedOIDs = selection.GetObjectIDs(); //save the selected OBJECTIDs to a list. var insp = new ArcGIS.Desktop.Editing.Attributes.Inspector(); //create the Inspector Then I loop through each selected OBJECTID: foreach (var oid in selectedOIDs) { insp.Load(currentLayer, oid); //use the current OBJECTID as you go through the loop of selected features Polyline theLine = insp.Shape as Polyline; //This works Segment theSegment = insp.Shape as Segment; //This will not cast....not quite sure what to do here MapPoint startPoint = theSegment.StartPoint; //This is ultimately what I want to get at } Since a Segment has a .StartPoint property, I think I need to cast my Polyline into a Segment, I'm just not sure how to do it. Of course, I could be totally wrong. Any advice on how to do this would be appreciated.

OK. It looks like the problem is a C# issue with the || operator and those null values. Not exactly sure why, but this seems to fix the problem: Map map = MapView.Active.Map; IEnumerable<Layer> gridLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_Grid", StringComparison.CurrentCultureIgnoreCase) >= 0); IEnumerable<Layer> localMunicipalityLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_LocalMunicipality", StringComparison.CurrentCultureIgnoreCase) >= 0); IEnumerable<Layer> administrativeAreaLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_AdministrativeArea", StringComparison.CurrentCultureIgnoreCase) >= 0); IEnumerable<Layer> communitiesLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_Communities", StringComparison.CurrentCultureIgnoreCase) >= 0); IEnumerable<Layer> depotAreaLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.LAND_DepotArea", StringComparison.CurrentCultureIgnoreCase) >= 0); IEnumerable<Layer> pressureZoneLayer = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf("GISWRKS1.WORKS.WAT_PressureZone", StringComparison.CurrentCultureIgnoreCase) >= 0); if (gridLayer.Count() == 0 || localMunicipalityLayer.Count() == 0 || administrativeAreaLayer.Count() == 0 || communitiesLayer.Count() == 0 || depotAreaLayer.Count() == 0 || pressureZoneLayer.Count() == 0) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Please add the LAND and Water Pressure Zone layers before proceeding.", "Missing Layers"); return; }

I'm trying to determine if specific layers are in the map before proceeding with more code. The following produces an error at the line where I am checking to the value == null of each layer. Is this the best way to do this? Or is there a better way to check for specific layers in the map?? protected override void OnClick() { var gridLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_Grid").FirstOrDefault() as BasicFeatureLayer; var localMunicipalityLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_LocalMunicipality").FirstOrDefault() as BasicFeatureLayer; var administrativeAreaLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_AdministrativeArea").FirstOrDefault() as BasicFeatureLayer; var communitiesLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_Communities").FirstOrDefault() as BasicFeatureLayer; var depotAreaLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_DepotArea").FirstOrDefault() as BasicFeatureLayer; var pressureZoneLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.LAND_PressureZone").FirstOrDefault() as BasicFeatureLayer; ****This is where I get the error!! If I check these one at a time, it works, but when combining with the || is when the error happens. In ArcMap 10.2, I have similar code running with no problems.**** if ((gridLayer == null) || (localMunicipalityLayer == null) || (administrativeAreaLayer == null) || (communitiesLayer == null) || (depotAreaLayer == null) || (pressureZoneLayer = null)) { ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("Please add the LAND and Water Pressure Zone layers before proceeding."); return; } ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show("All the layers are there!!"); }

Hi, I've created a WebMap in AGOL that uses clustering on a point feature class. All is working fine. When using the WebApp Builder 2.4 to create an app, I can add the above mentioned WebMap, but the clustering is not working. The points just display as regular points. I am using the 'Foldable' theme, and have only added the WebMap, no widgets or anything else. Is there something I need to set to get the clustering to work in the App?? Thanks,

I found it!! FrameworkApplication.SetCurrentToolAsync("esri_mapping_selectByRectangleTool");

Is there a listing available of ToolIDs within ArcPro? I've been looking through the API Reference and have only found one reference to esri_editing_SketchLineTool, but I would imagine there must be a whole list of them somewhere. What I want to do is automatically switch to the Select tool after a MapTool I am coding is finished running. Thanks,

Hi Uma, So I got it working, but was wondering if there is a better way. Is there a way to do what I want to do with just one event, or do I need to use all three to monitor the layers in the map?? This is in the Module1.cs of my MapTool code. protected override bool Initialize() { LayersAddedEvent.Subscribe((args) => { // Get the layers and also any selected OIDs for the AsBuilt and the SitePlan layers var asBuiltLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_AsBuilts").FirstOrDefault() as BasicFeatureLayer; var sitePlanLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_SitePlans").FirstOrDefault() as BasicFeatureLayer; // Check that the required layers are in the map. if (asBuiltLayer == null && sitePlanLayer == null) FrameworkApplication.State.Deactivate(StateID); else FrameworkApplication.State.Activate(StateID); } ); DrawCompleteEvent.Subscribe((args) => { // Get the layers and also any selected OIDs for the AsBuilt and the SitePlan layers var asBuiltLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_AsBuilts").FirstOrDefault() as BasicFeatureLayer; var sitePlanLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_SitePlans").FirstOrDefault() as BasicFeatureLayer; // Check that the required layers are in the map. if (asBuiltLayer == null && sitePlanLayer == null) FrameworkApplication.State.Deactivate(StateID); else FrameworkApplication.State.Activate(StateID); } ); LayersRemovedEvent.Subscribe((args) => { // Get the layers and also any selected OIDs for the AsBuilt and the SitePlan layers var asBuiltLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_AsBuilts").FirstOrDefault() as BasicFeatureLayer; var sitePlanLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.Drawings_SitePlans").FirstOrDefault() as BasicFeatureLayer; // Check that the required layers are in the map. if (asBuiltLayer == null && sitePlanLayer == null) FrameworkApplication.State.Deactivate(StateID); else FrameworkApplication.State.Activate(StateID); } ); return base.Initialize(); }

Yes, I am actually looking through the WorkingWithDAML example right now, but will check out the ConstructMarkerFromFont sample too. Thanks!

Excellent....thanks Charles!

Hi Charles, Yes, I was doing some copy/paste without really realizing what the MapPointBuilder was doing. Anyways.....just using the geometry parameter is working: modifyAsBuilts.Modify(asBuiltLayer, oid, geometry); One thing I am noticing is that the points in the map don't actually move until I click on 'OK' for the message box that pops up after I run modifyAsBuilts.Execute().....see below: modifyAsBuilts.Execute(); ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(abCount.ToString() + " As-Builts moved.", "Points moved"); I am guessing that I need some sort of a delay in there for the moving of the points to catch up to the processing of the code.....right?? Now on to the next phase; figuring out how to enable/disable this tool based on certain layers being in the map or not....and also changing the mouse cursor to the 'Explore' tool after the points have been moved. Any advice??
