I wanna a map bindable control to use in MVVM pattern but I have a problem. I created a class like this.     public class MapControl : Control     {         public static readonly DependencyProperty MapProperty =             DependencyProperty.RegisterAttached(             "Map",             typeof(Map),             typeof(MapControl),             new PropertyMetadata(OnMapChanged));         [Bindable(true)]         public Map Map         {             get { return (Map)GetValue(MapProperty); }             set { SetValue(MapProperty, value); }         }         private static void OnMapChanged(DependencyObject depObject, DependencyPropertyChangedEventArgs e)         {         }     } And in my ViewModel I created a new Map like this.     public class MainPageViewModel:INotifyPropertyChanged     {         private Map map;         public MainPageViewModel()         {             Map startMap = new Map();             startMap.Layers.Add(new ArcGISTiledMapServiceLayer { Url = "http://....." });                         Map = startMap;         }         public Map Map         {             get             {                 return map;             }             set             {                 map = value;                 OnPropertyChanged("Map");             }         } when I put breakpoints Map object in ViewModel or in Custom MapControl, Everything is working fine.     <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource ViewModel}}">         <Grid.ColumnDefinitions>             <ColumnDefinition/>             <ColumnDefinition/>             <ColumnDefinition/>         </Grid.ColumnDefinitions>                 <esriCustom:MapControl Map="{Binding Map}"  Grid.Column="0">                     </esriCustom:MapControl>     </Grid> I finally bind the ViewModel object Map to View MapControl. But nothing is appeared. ... View more

ArcGISDynamicMapServiceLayer mapServiceLayer = MyMap.Layers[8] as ArcGISDynamicMapServiceLayer; mapServiceLayer.VisibilityChanged += (s, e) => System.Windows.MessageBox.Show("ok"); and I have a checkbox that respoisble change the layer vsibility.             <CheckBox Content="ways"                       IsChecked="{Binding MyMap.Layers[8].Visible, Mode=TwoWay}"/> the chechbox working and changing the visibility of layer.

I wanna command bind to FeatureLayer, but not werking. I am using Prism library and Esri silverlght API. I read from prism document that Commands handle UI actions. Is the issue because FeatureLayer is not derived from Control? My code is folowing.             xmlns:esri="clr-namespace:ESRI.ArcGIS.Client;assembly=ESRI.ArcGIS.Client"             xmlns:cmd="clr-namespace:Infrastructure.Commands;assembly=Infrastructure"             xmlns:fcmd="clr-namespace:Infrastructure.Commands.FeatureLayerCommands;assembly=Infrastructure"         <esri:Map x:Name="MyMap"                   VerticalAlignment="Stretch"                   HorizontalAlignment="Stretch"                   cmd:MouseClick.Command="{Binding Map_Click}"                   cmd:SizeChange.Command="{Binding Size_Change}">                                          <esri:FeatureLayer ID="ff"                                Url="http://domain/arcgis/rest/services/serv/MapServer/4"                                Mode="OnDemand"                                fcmd:FeatureLayerMouseEnter.Command="{Binding FeatureLayer_MouseEnter}"                                                              />         </esri:Map> Map commands as following are working                   cmd:MouseClick.Command="{Binding Map_Click}"                   cmd:SizeChange.Command="{Binding Size_Change}" But feature layer command is not working and no error occuring.                  fcmd:FeatureLayerMouseEnter.Command="{Binding FeatureLayer_MouseEnter}"     Is the problem about FeatureLayer is not a UI Control ...
