Wpfmap.TrackOverlay.TrackMode -- help

#1

hi, 
when I use the TrackMode.Polygon mode to draw a area, I want to show out the x,y coordination near the point, and add a description to the area.
how could I do? 
thanks!

#2

add a question. 
 could I change the style of the points which constitude the area? 
 such as that  I would like to put a image in the location of the point. 
 greatful thanks! 
 yours liu.

Hi,Summer

thanks very much for your post code.

the code is perfect when I draw a area.

But the problem is when I edit the area drawed before,(such as rotate the area, the area’s points will move to the other location) the description of area points  is NOT changed When I finished the editing.



I changed a litter in your code, added a edit state with wpfMap1.EditOverlay.EditShapesLayer. 

And post it here.

Hope your back.



Best Regards

Thanks,

yours liu

Hi Liu, 
  
 This code should works for you: 
  
 Xaml 
 
<Button Content="Save" x:Name="btnSave" Click="btnTrack_Click" />
<Button Content="Edit" x:Name="btnEdit" Click="btnTrack_Click" />
  
  
 Background 
  
                       case "btnEdit"://add a edit state
                        drawMovePoint = false;
                        wpfMap1.TrackOverlay.TrackMode = TrackMode.None;
                        //add the TrackOverlay fetures to EditOverlay, and then clear the fetures in TrackOverlay
                        foreach (Feature feature in wpfMap1.TrackOverlay.TrackShapeLayer.InternalFeatures)
                        {
                            if (feature.GetShape() is PointShape) // Ignore all vertext label feature
                            {
                                continue;
                            }

                            wpfMap1.EditOverlay.EditShapesLayer.InternalFeatures.Add(feature);
                        }
                        wpfMap1.TrackOverlay.TrackShapeLayer.InternalFeatures.Clear();
                        wpfMap1.EditOverlay.CalculateAllControlPoints();//make it to edit
                        wpfMap1.Refresh(new Overlay[] { wpfMap1.EditOverlay, wpfMap1.TrackOverlay });
                        break;
                    case "btnSave":// Save edit state
                        drawMovePoint = false;
                        InMemoryFeatureLayer trackShapeLayer = wpfMap1.TrackOverlay.TrackShapeLayer;
                        trackShapeLayer.Clear();
                        foreach (Feature feature in wpfMap1.EditOverlay.EditShapesLayer.InternalFeatures)
                        {
                            if (feature.GetShape() is PolygonShape) // In this sample, we only handle polygon
                            {
                                System.Collections.ObjectModel.Collection<Vertex> vertexes = (feature.GetShape() as PolygonShape).OuterRing.Vertices;
                                for (int i = 0; i < vertexes.Count - 1; i++)
                                {
                                    Feature point = new Feature(vertexes[i].X, vertexes[i].Y);
                                    point.ColumnValues.Add(trackOverlay.ColumnKey, "X:" + vertexes[i].X + " Y:" + vertexes[i].Y);
                                    trackShapeLayer.InternalFeatures.Add(point);
                                }

                                trackShapeLayer.InternalFeatures.Add(feature);
                            }
                        }

                        wpfMap1.EditOverlay.EditShapesLayer.InternalFeatures.Clear();
                        wpfMap1.Refresh(new Overlay[] { wpfMap1.EditOverlay, wpfMap1.TrackOverlay });
                        if (wpfMap1.TrackOverlay.TrackShapeLayer.InternalFeatures.Count > 0)
                        {
                            wpfMap1.TrackOverlay.TrackShapeLayer.InternalFeatures.Remove("movePoint");
                        }
                        wpfMap1.TrackOverlay.TrackMode = TrackMode.None;
                        break;

Hi,

Tried downloading and running the application… It shows :



An unhandled exception of type ‘System.IO.IOException’ occurred in WpfDesktopEdition.dll



Additional information: The device is not ready.

What could be the possible reason?



Thanks,

Jacob

Hi Jacob, 
  
 We need more detail information about your scenario. 
  
 We want to know which application you are running and have you installed our WpfDesktopEdition(full/eval)? 
  
 What’s your environment now? 
  
 Because we haven’t met your exception information before. 
  
 Regards, 
  
 Don
