Pro 2.2 issues?
Sorry about the delayed reply. I looked over your snippets of code and tried to implement a sample to perform the same workflow. In my workflow I use RowChangedEvent and RowCreatedEvent subscriptions to make changes to the geometry of the subject row. The workflow looks like this: I modify an existing polygon or create a new one. Once the RowChanged / Created Event a firing, I use the new geometry and union all existing intersects of the new polygon with other polygons in that same layer. I then 'subtract' that union of intersects (if any) with my new geometry and overwrite the sketched geometry. So here is what it looks like in my add-in: First I 'create' a new polygon to my existing layer:
After I complete the sketch my Row Created event kicks in and the add-in logic to change my geometry run to prevent that my newly created geometry doesn't overlay any other polygons. I also update a description field in my new or modified feature to show if the sketched geometry was changed or not.
Hopefully I captured what you do in your add-in. Just in case I did here are some snippets from the sample:
// this is the feature layer that the add-in will process ... needs to be set somewhere in your add-in
private FeatureLayer _workedOnFeatureLayer = null;
// setup event listening ... somewhere in your code
QueuedTask.Run(() => {
_onRowChangedEvent = RowChangedEvent.Subscribe(OnRowChangedEvent, _workedOnFeatureLayer.GetTable());
_onRowCreatedEvent = RowCreatedEvent.Subscribe(OnRowCreatedEvent, _workedOnFeatureLayer.GetTable());
});
// ....
/// <summary>
/// Called for each row change
/// </summary>
/// <param name="args"></param>
private void OnRowChangedEvent(RowChangedEventArgs args)
{
UpdateStatusText ($@"Row changed: {args.EditType}");
UpdateRowIfNeeded(args);
}
/// <summary>
/// called for each newly created row
/// </summary>
/// <param name="args">
/// </param>
private void OnRowCreatedEvent(RowChangedEventArgs args)
{
UpdateStatusText ($@"Row created: {args.EditType}");
UpdateRowIfNeeded(args);
}
private void UpdateRowIfNeeded (RowChangedEventArgs args)
{
try {
var row = args.Row;
var geom = row["Shape"] as Geometry;
var rowCursorOverlayPoly = _workedOnFeatureLayer.Search (geom, SpatialRelationship.Overlaps);
Geometry geomOverlap = null;
while (rowCursorOverlayPoly.MoveNext())
{
var feature = rowCursorOverlayPoly.Current as Feature;
var geomOverlayPoly = feature.GetShape();
if (geomOverlayPoly == null) continue;
var geomDifference = GeometryEngine.Instance.Intersection(geom, geomOverlayPoly);
if (geomDifference == null) continue;
if (geomOverlap == null) {
geomOverlap = geomDifference;
continue;
}
geomOverlap = GeometryEngine.Instance.Union(geomOverlap, geomDifference);
}
if (!geomOverlap.IsNullOrEmpty())
{
args.Row["Description"] = "Corrected input polygon";
row["Shape"] = GeometryEngine.Instance.Difference(geom, geomOverlap);
}
else args.Row["Description"] = "No overlapping polygons found";
}
catch (Exception e) {
MessageBox.Show($@"Error in UpdateRowIfNeeded for OID: {args.Row.GetObjectID()} in {_workedOnFeatureLayer.Name}: {e.ToString()}");
}
}
Looks like my add-in works for both file and database connections, I will try a feature service tomorrow.
