Editor class Edit_Completed EditVertices

Bende_Vries — Thu, 16 Jun 2011 15:31:14 GMT

Hi,

Using version 2.2. In the editor_EditCompleted the EditVertices graphic.geometry does not show the correct result. After having moved a graphic I would expect the geometry of the changed graphic.geometry to have the value of the moved location.
I am using a graphicslayer to test this. Here is the code for the EditCompleted. The geometry in the change.Graphic.Geometry is identical to the geometry in the original graphic. Any idea what is wrong ?

void esriEditor_EditCompleted(object sender, Editor.EditEventArgs e)
        {
            switch (e.Action)
            {
                case Editor.EditAction.EditVertices:
                    if (e.Edits.Count() > 0)
                    {
                        ESRI.ArcGIS.Client.Editor.Change change = e.Edits.First();
                        if (change.Graphic != null)
                        {
                            // Replace the geometry of the original graphic with the changed geometry
                            editGraphicOriginal.Geometry = change.Graphic.Geometry;
                        }
                    }
                    break;
            }
        }

I cannot reproduce the issue with the following code. Place a breakpoint after setting resultGeometry, so you may compare originalGeometry versus resultGeometry. After the move, edit.Graphic.Geometry should no longer be the same as originalGeometry. Place them in your watch window so you may compare.

Jennifer,

Thanks for the quick response. I tried your sample and it works fine. So, there is nothing wrong with the EditVertices. The only difference I can see is that I use the editor from code and not from xaml. Will look further into it. Thanks again.
