Moving selected features

BrianBulla — Tue, 22 Aug 2017 19:49:15 GMT

Hi,

i'm having some trouble trying to figure out how to move a bunch of selected features from a specific point layer in the map. This is what I have so far:

//****Get all of the selected ObjectIDs from the VLS layer.
var abLayer = MapView.Active.Map.FindLayers("GISWRKS1.WORKS.AsBuilts").First() as BasicFeatureLayer;
var selection = abLayer.GetSelection();
IReadOnlyList<long> selectedOIDs = selection.GetObjectIDs(); //save the selected OBJECTIDs to a list.

var insp = new ArcGIS.Desktop.Editing.Attributes.Inspector(); //create the Inspector

var moveFeature = new EditOperation();

moveFeature.Name = "Move AsBuilts";

//Loop through each selected OBJECTID
foreach (var oid in selectedOIDs)
{
insp.Load(abLayer, oid);

moveFeature.Move(..............); //**** This is where I get stuck....I don't know what to do

}

I think my approach is all wrong, but I'm not sure what to do. I'm not exactly sure how to interpret this: ArcGIS Pro 2.0 API Reference Guide

Thanks

Hi Brian,

This snippet below worked for me. The Move method has a couple of overrides you can use. Move method from Pro API Reference guide

 QueuedTask.Run(() =>
            {
                //Get all of the selected ObjectIDs from the layer.
                var abLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
                var selection = abLayer.GetSelection();

                // set up a dictionary to store the layer and the object IDs of the selected features
                var selectionDictionary = new Dictionary<MapMember, List<long>>();
                selectionDictionary.Add(abLayer as MapMember, selection.GetObjectIDs().ToList());
                var moveFeature = new EditOperation();
                moveFeature.Name = "Move features";
                moveFeature.Move(selectionDictionary, 10, 10);  //specify your units along axis to move the geometry

                moveFeature.Execute();
            });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks Uma. That is working now.

Do you know if there is a similar method that will move the feature to a specific coordinate?? Or is there a built-in method for calculating the offset between two coordinates??

Hi Brian

If you use EditOperation's Modify method you can move the point to a specific coordinate -

 QueuedTask.Run(() =>
            {
                //Get all of the selected ObjectIDs from the layer.
                var abLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
                var selection = abLayer.GetSelection();
                var oid = selection.GetObjectIDs().FirstOrDefault();

                var moveToPoint = new MapPointBuilder(1.0, 2.0, 3.0, 4.0, MapView.Active.Map.SpatialReference); //can pass in coordinates.

                var modifyFeature = new EditOperation();
                modifyFeature.Name = "Move features";
                modifyFeature.Modify(abLayer, oid, moveToPoint.ToGeometry());  //Modify the feature to the new geometry 
                modifyFeature.Execute();
            });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Also, the GeometryEngine has a "Distance" method that could be used to calculate the offset distance between 2 points (to plug into the "Move" method - For the original Move method snippet).

Thanks

Uma

Thanks again Uma. You have been a great help!

I tweaked yours to work with a selection of features. Here is my final solution for anyone else who may be following this thread:

// 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;

// variable for the coordinate of the mouse click in the whatever the SpatialReference of the map is

var coord = GeometryEngine.Instance.Project(geometry, MapView.Active.Map.SpatialReference) as MapPoint;

var moveToPoint = new MapPointBuilder(coord.X, coord.Y, MapView.Active.Map.SpatialReference);

// create counter for showing final results

int abCount = 0;

// start the EditOperation

var modifyAsBuilts = new EditOperation();

modifyAsBuilts.Name = "Move As-Builts and Site Plans";

// Get any selected OIDs for the layer, and move each point to the mouse click point.

if (asBuiltLayer != null)

{

var selectedAB = asBuiltLayer.GetSelection();

IReadOnlyList<long> selectedAsbuiltOIDs = selectedAB.GetObjectIDs();

foreach (var oid in selectedAsbuiltOIDs)

{

modifyAsBuilts.Modify(asBuiltLayer, oid, moveToPoint.ToGeometry());

abCount++;

}

modifyAsBuilts.Execute();

Brian, thanks for taking the time on this.

FYI: on:

// variable for the coordinate of the mouse click in the whatever the SpatialReference of the map is

var coord = GeometryEngine.Instance.Project(geometry, MapView.Active.Map.SpatialReference) as MapPoint;

var moveToPoint = new MapPointBuilder(coord.X, coord.Y, MapView.Active.Map.SpatialReference);<-- not needed

coord is a MapPoint already (reading your code).

So this:

modifyAsBuilts.Modify(asBuiltLayer, oid, moveToPoint.ToGeometry());

can become this:

modifyAsBuilts.Modify(asBuiltLayer, oid, coord);

I think you may have some copy/paste inheritance from Uma's code where she used a MapPointBuilder because she built the point from scratch.

One other point (no pun intended ;-). I noticed this:

var coord = GeometryEngine.Instance.Project(geometry, MapView.Active.Map.SpatialReference) as MapPoint;

I don't now what the overall context of the "surrounding" code is but I suspect that your digitized geometry may already be in the map spatial reference. Can you just try:

modifyAsBuilts.Modify(asBuiltLayer, oid, geometry);

using the geometry directly and see if that works?

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??

CharlesMacleod — Thu, 07 Sep 2017 18:15:49 GMT

If you have this:

QueuedTask.Run(() => {

op.Execute();

MessageBox.Show("...");

}

you probably won't see the move (until after).

Instead, do this:

await QueuedTask.Run(() => {

op.Execute();

};

MessageBox.Show("...");

and you will. Note, if you add "await", you must also add "async" to the method declaration (eg SketchComplete or whichever it is).

Excellent....thanks Charles!

Re: Moving selected features

UmaHarano — Thu, 07 Sep 2017 19:14:04 GMT

To enable/disable your tool based on layers, you can use states and conditions. There is ConstructMarkerFromFont sample that demonstrates this.

Re: Moving selected features

BrianBulla — Thu, 07 Sep 2017 19:30:30 GMT

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

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();

}

Hi Brian

To accomplish what you are doing, I would listen to the following events:

* You need to know when a map is initialized and the TOC is available. This event will help with that - MapViewInitializedEvent

* You will have to also listen to the ActiveMapViewChangedEvent to see when the active map view changes.

* Finally you can listen to MapMemberPropertiesChangedEvent to see if new layers being added\removed affects your tool.

* You might have to check the MapClosedEvent also.

The ProceduralSymbolLayers sample does something very similar - If you check the Module class file of this sample.

Thanks

Uma

Uma,

Thanks for this snippet, I was wondering is it possible to use Attributes from a feature layer that has fields for Lat Longs instead of using specific coordinates? I have a tool that is working using the above snippet, but I am having difficulties applying the Lat and Long fields to the moveToPoint variable.
