Hi,
I created 2 layers in a xamMap. One layer displays world map. In other layer, I added the SymbolElements which represents the cities of the countries based on their corresponding longitude and latitude. But all the SymbolElements are displaying at the same location.
The project including the shape file can be downloaded at the following link.

Please kindly point out if i am missing something.
Your help will be highly appreciated.

Hi NNT,
Please take a look at this forum post: http://community.infragistics.com/forums/p/36373/211645.aspx#211645
Hope that helps.

Hi Ivan,
I have one more question. :)
How could I add SymbolElement at the mouse-click location ? I add event handler to xamMap.MapMouseLeftButtonDown event and try to get the position from MapMouseButtonEventArgs.
The problem is the somybol element is displaying at the same location.
Here is my code snippet. I am using the same project which i mentioned before.
void MainMap_MapMouseLeftButtonDown(object sender, MapMouseButtonEventArgs e) { thisLocatorLayer.WorldRect = thisWorldLayer.WorldRect; var pointer = new SymbolElement { SymbolOrigin = e.Position, SymbolType = MapSymbolType.Bubble, SymbolSize = 5, Fill = new SolidColorBrush(Colors.Red), Stroke = new SolidColorBrush(Colors.Purple) }; thisLocatorLayer.Elements.Clear(); thisWorldLayer.Elements.Add(pointer); }
Thanks much for your help.
I'm glad we solved the issue :) Please let me know if you have more questions.
You are the light of my life.
Thanks so very much.
Thanks for providing the .prj file. With the information from it I have been able to import the shapefile and add the 3 SymbolElements. Please try the following code snippet:
<ig:XamMap x:Name="MainMap" Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" IsAutoWorldRect="True" MapProjectionType="Miller37" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" WindowZoomMaximum="30" WindowZoomMinimum="0"> <ig:MapNavigationPane x:Name="Navigation" Visibility="Visible" HorizontalAlignment="Right"/> <ig:XamMap.Layers> <ig:MapLayer LayerName="WorldLayer" FillMode="Choropleth" HorizontalContentAlignment="Center" VisibleFromScale="0" HorizontalAlignment="Center" VerticalAlignment="Center" VerticalContentAlignment="Center"> <ig:MapLayer.Reader> <ig:ShapeFileReader Uri="Shapefiles/world2/world"> <ig:ShapeFileReader.CoordinateSystem> <ig:CoordinateSystem UnitType="M" FalseEasting="0.0" FalseNorthing="0.0" > <ig:CoordinateSystem.Projection> <ig:MillerCylindrical EllipsoidType="WGS84" CentralMeridian="10.0" /> </ig:CoordinateSystem.Projection> </ig:CoordinateSystem> </ig:ShapeFileReader.CoordinateSystem> </ig:ShapeFileReader> </ig:MapLayer.Reader> </ig:MapLayer> <ig:MapLayer LayerName="PointLayer"/> </ig:XamMap.Layers></ig:XamMap>
Also I have changed the Laayoune's coordinates from:
citiList.Add(new CitiData { Longitude = -1.32, Latitude = 27.15, CityName = "..." });
to:
citiList.Add(new CitiData { Longitude = -13.2, Latitude = 27.15, CityName = "..." });
The result is:
