Can the SketchEditor be used to update existing Geometries of features?

Question

Hi,

Does the SketchEditor allows editing only on the geometries created by SketchEditor itself ?

Can't we update the geometries of existing features in static FeatureCollection using SketchEdior ?

Thankyou so much for the help Jenifer, It worked

I tried your code and it works for me. With RequireSelectionBeforeDrag=True (default), you'll need to select the handle for vertex, scale, rotate, geometry outline before you're able to move them. Maybe you're attempting to drag another vertex while the last one is selected? If you expect the handles to move with pointer or touch gesture move, you can set this to property to false so it does not require you to tap on the handle first.

Hi Jenifer,

Thank You for your help, your guidance is helping me a lot to understand.

But I have one small doubt, when I try to edit any feature like Polygon or Polyline , It allows me to drag only one point out of so many highlighted vertices, I also tried to set the edit configuration of SketchEditor , but I am able to edit using only one point out of all the highlighted vertices.

// Set the sketch editor configuration to allow vertex editing, resizing, and moving
layerSelected.SetFeatureVisible(featureSelected,true);
var config = myMapView.SketchEditor.EditConfiguration;
config.RequireSelectionBeforeDrag = true;
config.AllowRotate = true;
config.VertexEditMode = SketchVertexEditMode.InteractionEdit;
config.AllowVertexEditing = true;
config.ResizeMode = SketchResizeMode.Uniform;
config.AllowMove = true;
var project = !myMapView.SpatialReference.IsEqual(geometry.SpatialReference);
if (project)
{
geometry = GeometryEngine.Project(geometry, myMapView.SpatialReference);
}
geometry = await myMapView.SketchEditor.StartAsync(geometry,SketchCreationMode.FreehandPolygon,config);
if (project)
{
geometry = GeometryEngine.Project(geometry, featureSelected.Geometry.SpatialReference);
}
featureSelected.Geometry = geometry;

await featureSelected.FeatureTable.UpdateFeatureAsync(featureSelected);

How can I allow editing from all the vertices ? As I am able to edit by only one vertex even after setting the edit configuration of Sketch Editor.

Thanks in advance
