Can't move a rectangle just created

xiaoguangyan — Thu, 01 Jun 2017 02:14:14 GMT

I happen to meet a strange problem, I use the "SketchEditor" to draw some geometry then use geometry to create feature and save them in different types of featurecollectiontables, WHEN I create " rectangle feature", I move it and save, the feature position remain unchange,all other like circle,polygon etc don't have this issue! so strange!

Could you share a little sample that reproduces the issues with more detailed steps how to reproduce?

Thanks, I will post the sample later, but now I have another question, when using "SketchEditor" to draw geometry in 10.2.7, the geometry can be draged by choosing whole area like drag a polygon ; but in 100.0 , I can only drag by choosing outline, I wanna drag things like in 10.2.7

I believe for polygons the default is to not allow move. You can use the SketchEditConfiguration and set AllowMove=true.

Hi Xiaguang,

You might be hitting some of the expected behavior changes with SketchEditor.

SketchEditor.StartAsync(SketchCreationMode.Rectangle) ‍

is equivalent to

var geometry = await Editor.RequestShapeAsync(DrawShape.Rectangle);
geometry = await Editor.EditGeometryAsync(geometry);‍‍‍‍‍‍

Unless you specify optional parameter drawAndShape to false (default value: true), your draw will continue in edit mode.

You can also complete draw/edit using CompleteCommand just as before

Using command binding

<Button Content="Complete"
        Command="{Binding ElementName=MyMapView, Path=SketchEditor.CompleteCommand}" />‍‍

or programmatically invoking command

if (MyMapView.SketchEditor.CompleteCommand.CanExecute(null))
    MyMapView.SketchEditor.CompleteCommand.Execute(null);‍‍

To move the geometry, you tap on the outline of polyline/polygon while in edit mode. Once outline is highlighted, you can drag the feature just as before.

In 10.2.x, you may drag the feature right away but this may have caused unintentional edit (moved vertices/geometry by mistake). You also may complete interactively by tapping the geometry but this may have caused unintentional completion and also did not allow a vertex be added inside the geometry.

As Morten mentioned, there are default configurations in SketchEditConfiguration. You may have noticed that AllowVertexEditing is only enabled by default for SketchCreationMode.Polyline/Polygon or Polygon/Polyline geometry but AllowMove should be enabled for all types and you should be able to override default edit configuration.

I hope that works. Please let us know, otherwise. Thanks.

Hi Morten Nielsen
I have set AllowMove to True, I mean I can't move a polygon by draging it's area, but can move it by draging it's outline, in 10.2.7, we can move a polygon by draging it's area.

the pic up is ArcGIS Runtime SDK for .NET 10.2.7 samples----Editing------Draw and Edit Graphics,here we can move a polygon by draging it's area.

Hi, Jennifer

I think in 10.2.7 is more convenient, because in 100 moving polygon by dragging outline is kind of hard to choose.

I know this is quite an old post but EditConfiguration has `RequireSelectionBeforeDrag` property since v100.2 when set to false will have the same 10.2.x behavior geometry or vertex/scale/rotate tools can be dragged without being tapped or highlighted first.

Hi Jennifer

I set EditConfiguration property`RequireSelectionBeforeDrag` to false, and it's the same, I have to tap the outline and highlight it then I can move the polygon by drag the outline other than the polygon area

Re: Can't move a rectangle just created

JenniferNery — Sun, 12 Dec 2021 03:31:27 GMT

Hi Xiaoguang,

`RequireSelectionBeforeDrag` only changes the behavior of when a geometry or tool (vertex, scale, rotate) gets moved, it would be immediate once dragged, no need to tap/highlight. But you are right, in 10.2.x, one can drag geometry from the fill/area and in 100.x one can drag geometry only from its outline. The reason for this design is to allow vertices to be added/moved inside the geometry fill as well which was a limitation in 10.2.x. I will forward this request to runtime design lead for consideration. We have also included in 100.2.x enhancements ability to select, insert/move/delete vertices programmatically - I'm not sure if helps your current workflow.

Meanwhile, if it's a challenge to select the polygon outline, you might want to update SketchEditor.Style.

// change symbol
MyMapView.SketchEditor.Style = new SketchStyle()
{
    LineSymbol = new SimpleLineSymbol(SimpleLineSymbolStyle.Solid, Colors.Green, 8)
};

// or just increase width of default symbol
(MyMapView.SketchEditor.Style.LineSymbol as LineSymbol).Width = 8;‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You may also at any time without restarting your draw/edit turn on/off any of the configuration

<CheckBox Content="VertexEditing" IsChecked="{Binding ElementName=MyMapView, Path=SketchEditor.EditConfiguration.AllowVertexEditing, Mode=TwoWay}"/>‍‍‍

Hopefully, these make interacting with polygon outline better.

I am seeing the exact same behavior as Xiaoguang. I was pretty stoked when I saw the new RequireSelectionBeforeDrag property, but it doesn't seem to work as advertised. The selecting the border to move stuff is driving our customers nuts. It's not necessarily a problem to select the outline, but they just don't know that they have to do that to initiate a move. It's not a good user experience, so being able to do it the old way would be a big win for us.

Not sure if I'm doing something wrong, but here are the EditConfiguration properties I set up before any edits:

MainMapView.SketchEditor.EditConfiguration.AllowMove = true;
MainMapView.SketchEditor.EditConfiguration.AllowRotate = true;
MainMapView.SketchEditor.EditConfiguration.AllowVertexEditing = true;
MainMapView.SketchEditor.EditConfiguration.ResizeMode = SketchResizeMode.None;
MainMapView.SketchEditor.EditConfiguration.RequireSelectionBeforeDrag = false;

Even after setting those properties when I click on a graphic and drag the map pans. I still need to tap the line or polygon boundary to select it. Then I can click and drag the object. Setting the RequireSelectionBeforeDrag property does not seem to have any effect.

After I set those properties RequireSelectionBeforeDrag is false as it should be. The next thing I do is start an edit session with the selected graphic like this:

graphic.Geometry = await ApplicationManager.MainMapView.SketchEditor.StartAsync(editGeom, sketchCreationMode);

Immediately after my edit is done the RequireSelectionBeforeDrag property is true for some reason. Head scratcher there as I never explicitly set it to true. I would expect it to remain false until I tell it otherwise. I wonder if this is part of the reason it's not working as we expect it to.

Thank you, Andy. We have an open design issue for allowing drag from fill.

As for the EditConfiguration not taking effect next time - is because it's not a global setting.

StartAsync has an optional parameter that accepts SketchEditConfiguration. If this is not supplied, we determine based on the type of geometry whether to enable scale/rotate/vertex editing, etc. The default setting for RequireSelectionBeforeDrag is true. To set it to false, you can either, pass the parameter or set it after StartAsync or set to false in a two-way binding.

MyMapView.SketchEditor.StartAsync(
    SketchCreationMode.Polygon,
    new SketchEditConfiguration() { RequireSelectionBeforeDrag = false } // as parameter
    );

// or set after StartAsync
MyMapView.SketchEditor.EditConfiguration.RequireSelectionBeforeDrag = false; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍

If you used two-way binding, you would notice that next call to StartAsync will reset this back to true(checked).

<CheckBox Content="Select" IsChecked="{Binding ElementName=MyMapView, Path=SketchEditor.EditConfiguration.RequireSelectionBeforeDrag, Mode=TwoWay}"/>‍‍‍

Boom! I knew I must have been missing something. It works a lot better now, but we do still have to click on the poly boundary to move it. Will be very nice to be able to drag from fill. Thanks for your help Jennifer!

I agree that the requirement of selecting the outline to move a shape is an extremely confusing and difficult to use UX. I really hope this can be changed to work from the fill in a future update.

I wasted 3 hours today trying to figure out why I was not able to move my polygons and then happened to stumble upon this post. At the very least it would be nice to see the API/docs or samples updated with some information about the expected UI workflow for moving geometries.
