Dear friends, PLEASE HELP ME....STRUGGLING TO SOLVE THIS ISSUE
I developed one application for showing googlemap in my silverlight based ESRI application based on the code explaining here in this link http://rexdotnet.blogspot.com/2010/09/use-google-maps-with-arcgis-silverlight.html Everything working perfect except one problem at the time of zoom and pan the map. When I try to display a polygon on my googlemap,First time it is showing on correct location .But when I zoom or pan the map ,polygon is not moving with map.After pan the map polygon is showing in another location . how to solve this issue? *Adding polygon using the following code* Private Sub AddPolygonGraphics(coordinateString1 As String, Gname As String, Gdesc As String) Dim graphicsLayer As GraphicsLayer = TryCast(MyMap.Layers("MyGraphicsLayer"), GraphicsLayer) Dim pointConverter As New PointCollectionConverter() Dim pointCollection1 As ESRI.ArcGIS.Client.Geometry.PointCollection = TryCast(pointConverter.ConvertFromString(coordinateString1), ESRI.ArcGIS.Client.Geometry.PointCollection) Dim polygon1 As New ESRI.ArcGIS.Client.Geometry.Polygon() polygon1.Rings.Add(pointCollection1) _activeSymbol = TryCast(LayoutRoot.Resources("DefaultFillSymbolT"), Symbol) Dim graphic As New Graphic() With { .Geometry = mercator.FromGeographic(polygon1), .Symbol = _activeSymbol } polygon1.SpatialReference = New SpatialReference(4326) Dim strhotspot As String = "" strhotspot = Trim(Gname) If Gdesc <> "" Then strhotspot = strhotspot & "," & Trim(Gdesc) End If graphicsLayer.Graphics.Add(graphic) MyMap.ZoomTo(graphicsLayer.FullExtent) End Sub *USING THE BELOW CODE I AM CALLING THE MAP EACH TIME* Imports ESRI.ArcGIS.Client Imports ESRI.ArcGIS.Client.Geometry Public Class GoogleStaticMapLayer Inherits DynamicMapServiceLayer Private Shared mercator As New ESRI.ArcGIS.Client.Projection.WebMercator() Private Const cornerCoordinate As Double = 20037508.3427892 Private Const WKID As Integer = 102100 Public Sub New() MyBase.New() End Sub Private Property Lods() As Lod() Get Return m_Lods End Get Set(value As Lod()) m_Lods = Value End Set End Property Private m_Lods As Lod() Public Overrides Sub Initialize() Me.FullExtent = New ESRI.ArcGIS.Client.Geometry.Envelope(-cornerCoordinate, -cornerCoordinate, cornerCoordinate, cornerCoordinate) With { _ .SpatialReference = New SpatialReference(WKID) _ } Me.SpatialReference = New SpatialReference(WKID) Lods = New Lod(20) {} Dim resolution As Double = cornerCoordinate * 2 / 256 For i As Integer = 0 To Lods.Length - 1 Lods(i) = New Lod() With { _ .Resolution = resolution _ } resolution /= 2 Next MyBase.Initialize() End Sub Public Overrides Sub GetUrl(extent As ESRI.ArcGIS.Client.Geometry.Envelope, width As Integer, height As Integer, onComplete As DynamicMapServiceLayer.OnUrlComplete) Dim geogCenterPoint As MapPoint = Nothing Dim mapURL As String = Nothing Try Dim currentResolution As Double = extent.Width / width Dim currentLodIndex As Integer = 0 Dim requestWidth As Integer = 0 Dim requestHeight As Integer = 0 For i As Integer = 0 To Lods.Length - 1 Dim lod As Lod = Lods(i) currentLodIndex = i If CInt(lod.Resolution) <= CInt((currentResolution)) Then requestWidth = CInt(extent.Width / lod.Resolution) requestHeight = CInt(extent.Height / lod.Resolution) Exit For End If Next geogCenterPoint = TryCast(mercator.ToGeographic(extent.GetCenter()), MapPoint) mapURL = String.Format("http://maps.google.com/maps/api/staticmap?center={0},{1}&zoom={2}&size={3}x{4}&scale=2&maptype=roadmap&sensor=false&key=AIzaSyDoFucUPlE1lpMxNqc1-cN-dihqGZuLYUw";, geogCenterPoint.Y, geogCenterPoint.X, currentLodIndex, requestWidth, requestHeight) Catch ex As Exception Return End Try onComplete(mapURL, width, height, New ESRI.ArcGIS.Client.Geometry.Envelope() With { _ .XMin = extent.XMin, _ .YMin = extent.YMin, _ .XMax = extent.XMax, _ .YMax = extent.YMax _ }) End Sub End Class Please help me.It is very urgent...Thank UUUU -- You received this message because you are subscribed to the Google Groups "Google Maps API V2" group.
