Hi, I have 2 questions... 1. I have a legend which declared with checkboxes for layers visibility (see XAML). and i have a function which zoom to maximumScale of a given FeatureLayer. (see code below) When i call the function it zoom to the maximum featureLayer scale and i see on map its graphics (it is still visible and did not disappeared), but the legend checkbox is not enabled (guessing the IsInScaleRange property returns false) what am i missing (if i see it on map it should also be enabled on legend - right)? 2. Is it possible to register an event or some other way of handling when a checkbox is checked on a layerItem in order to reverse the check action on a specific layerItem?

Hi, I have loaded MPK file to localMapService and want to calculate how many levels of zooming do i have. Is it possible? My main task is to receive from a user the zoom level (integer) he want to zoom to, and i can't figure it out if it possible to calculate the extent according to required zoom level. ... View more

Hi all, I am developing a generic map loader which get as a parameter a path to a MPK file (i don't know what each MPK consists of) I am trying to load a custom MPK with its features Layers, and i have encountered several problems: 1. if i load the mpk to ArcGISLocalDynamicMapServiceLayer the map displaying well but i can't interact with map (Clicking ect..) 2. If i load the mpk according to ArcGISLocalDynamicMapServiceLayer.Layers (Attached code) - each one of the layers into FeatureLayer it is not displaying well (polygons of some layers are not seen). 3. A Graphic Symbol of each one of the featureLayer.Graphics return null (this did not happen with 10.1) What is the best way to load a custom local map and its features? if (layer is ArcGISLocalDynamicMapServiceLayer) {     LocalMapService.GetServiceAsync(layerURI, (localMapService) => {      ArcGISLocalDynamicMapServiceLayer localLayer = layer as ArcGISLocalDynamicMapServiceLayer;      localLayer.EnableDynamicLayers = true;      localLayer.Service = localMapService;            localLayer.Initialize();            localLayer.Initialized += new EventHandler<EventArgs>(localLayer_Initialized); } } void localLayer_Initialized(object sender, EventArgs e) {             ArcGISLocalDynamicMapServiceLayer localMapService = sender as ArcGISLocalDynamicMapServiceLayer;             if (localMapService != null)             {                 List<LayerInfo> layers = localMapService.Layers.Reverse().ToList();                 foreach (LayerInfo layerInfo in layers)                 {                     if (layerInfo.SubLayerIds == null || layerInfo.SubLayerIds.Length == 0)                     {                         ArcGISLocalFeatureLayer ftLayer= new ArcGISLocalFeatureLayer(localMapService.Service, layerInfo.ID);                         //this is not affecting visibility of the layer ??? why?                         ftLayer.Visible = layerInfo.DefaultVisibility;                                                 ftLayer.OutFields = new ESRI.ArcGIS.Client.Tasks.OutFields() { "*" };                         ftLayer.Initialized += new EventHandler<EventArgs>(ftLayer_Initialized);                         ftLayer.InitializationFailed += new EventHandler<EventArgs>(ftLayer_InitializationFailed);                         ftLayer.UpdateCompleted += new EventHandler(ftLayer_UpdateCompleted);                         ftLayer.MouseRightButtonUp += new GraphicsLayer.MouseButtonEventHandler(ftLayer_MouseRightButtonUp);                         ftLayer.MouseLeftButtonDown += new GraphicsLayer.MouseButtonEventHandler(ftLayer_MouseLeftButtonDown);                         ftLayer.MouseLeftButtonUp += new GraphicsLayer.MouseButtonEventHandler(ftLayer_MouseLeftButtonUp);                                         _map.Layers.Add(childLayer);                     }                 }             } } void ftLayer_UpdateCompleted(object sender, EventArgs e) {              GraphicsLayer graphicLayer = layer as GraphicsLayer;               foreach (var graphic in graphicLayer.Graphics)                 { //graphic.Symbol returns null in 10.2 (in 10.1 returned the Symbol value)?????????                     if (graphic.Symbol is PictureMarkerSymbol)                     {                         if (dicLayerGraphics.ContainsKey(layerId.ToString()) == false)                         {                             dicLayerGraphics[layerId.ToString()] = new List<Graphic>();                             dicLayers[layerId.ToString()] = graphicLayer;                         }                         dicLayerGraphics[layerId.ToString()].Add(graphic);                     }                 } } ...
