Hi, I'm Creating a "thematics map tool", and i'm having trouble to set a property to change the opacity on the Layer I present with them. <ListBox x:Name="nomeTematico" Grid.Row="1" Margin="0,0,0,217" Background="#FFFEFEFE"              BorderBrush="{x:Null}" Foreground="#FF245489">     <ListBox.ItemTemplate>         <DataTemplate>             <StackPanel Orientation="Horizontal">                 <CheckBox Margin="2"                           IsChecked="{Binding DefaultVisibility}"                           Tag="{Binding ID}"                           ClickMode="Press"                           Checked="AtivaVisualizacaoDeTematico"                           Unchecked="DesativaVisualizacaoDeTematico"/>                 <Slider Maximum="1" Value="{Binding Opacity??, Mode=TwoWay}" Width="40" Margin="0,0,8,0" />                 <TextBlock Text="{Binding Name}" VerticalAlignment="Center"/>             </StackPanel>         </DataTemplate>     </ListBox.ItemTemplate> </ListBox> <ListBox x:Name="legendaTematico" BorderBrush="{x:Null}" Margin="20,43,0,5" Grid.Row="1"/> This is the code to my thematics window, and the following code shows the moment I select a theme: private void AtivaVisualizacaoDeTematico(object sender, RoutedEventArgs e) {     if (sender is CheckBox)     {         this.tematicoExibido = sender as CheckBox;     }     if (this.tematicoExibido != null)     {         string serviceName = this.comboTematico.SelectedItem as string;         int indiceDaCamada = (int)tematicoExibido.Tag;         ArcGISDynamicMapServiceLayer camadaDeTematicos = mapaEmExecucao.Layers["Mapa Tematicos"] as ArcGISDynamicMapServiceLayer;                 List<int> subCamadasVisiveis;         if (camadaDeTematicos.VisibleLayers != null)         {             subCamadasVisiveis = camadaDeTematicos.VisibleLayers.ToList();         }         else         {             subCamadasVisiveis = new List<int>();         }         if (!subCamadasVisiveis.Contains(indiceDaCamada))         {             subCamadasVisiveis.Add(indiceDaCamada);         }                camadaDeTematicos.VisibleLayers = subCamadasVisiveis.ToArray();     } } private void DesativaVisualizacaoDeTematico(object sender, RoutedEventArgs e) {     if (sender is CheckBox)     {         this.tematicoExibido = sender as CheckBox;     }     if (this.tematicoExibido != null)     {         string serviceName = this.comboTematico.SelectedItem as string;         int indiceDaCamada = (int)tematicoExibido.Tag;         ArcGISDynamicMapServiceLayer camadaDeTematicos = mapaEmExecucao.Layers["Mapa Tematicos"] as ArcGISDynamicMapServiceLayer;         List<int> subCamadasVisiveis;         if (camadaDeTematicos.VisibleLayers != null)         {             subCamadasVisiveis = camadaDeTematicos.VisibleLayers.ToList();         }         else         {             subCamadasVisiveis = new List<int>();         }         if (subCamadasVisiveis.Contains(indiceDaCamada))         {             subCamadasVisiveis.Remove(indiceDaCamada);         }         camadaDeTematicos.VisibleLayers = subCamadasVisiveis.ToArray();     } } ...

Hi, I'm build a coordinate search to my appication. To do so, I'm using the following MarkerSymbol, to show the coordinates and a image that represents the point. <ResourceDictionary     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:esri="http://schemas.esri.com/arcgis/client/2009">     <esri:MarkerSymbol x:Key="MarcadorCustomizadoFerramentaCoordenadas" OffsetX="8" OffsetY="31">         <esri:MarkerSymbol.ControlTemplate>             <ControlTemplate>                 <StackPanel Orientation="Horizontal">                     <Image Source="/ViewModel;component/RecursosGraficos/Imagens/marcadorCoordenadas.png"/>                     <Border BorderBrush="Green" Background="White" BorderThickness="1">                         <TextBlock Text="{Binding [Coordenadas]}" TextAlignment="Left" VerticalAlignment="Center"                                    FontFamily="Portable User Interface"/>                     </Border>                 </StackPanel>             </ControlTemplate>         </esri:MarkerSymbol.ControlTemplate>     </esri:MarkerSymbol>     </ResourceDictionary> The problem in this code is that the Binding get no value. This Binding was originaly on a MapTip code on the GraphicsLayer, and there it works fine. Does Anyone knows how to make it work as a Graphic Symbol? This is how I set the Marker as Symbol of the Graphic: private void AdicionaPontoNoGraficsLayer(MapPoint ponto) {     mapaEmExecucao.PanTo(ponto);     Graphic bandeiraBuscaPorCoordenadas = new Graphic();     bandeiraBuscaPorCoordenadas.Attributes.Add("Coordenadas",                                                 string.Format("X: {0}\nY: {1}",                                                              Math.Round(ponto.X, 4),                                                              Math.Round(ponto.Y, 4)));     bandeiraBuscaPorCoordenadas.Geometry = ponto;     bandeiraBuscaPorCoordenadas.Symbol = RecursosGraficos.RecursosGraficos.ObtemImagem(RecursosGraficos.RecursosGraficos.Imagens.MarcadorCustomizadoFerramentaCoordenadas);     GraphicsLayer resultadoBuscaCoordenada = mapaEmExecucao.Layers["ExibePontosFerramentaCoordenadas"] as GraphicsLayer;     resultadoBuscaCoordenada.Graphics.Add(bandeiraBuscaPorCoordenadas); } ...

Hi, In my application I need to get a new image of the my map every time it is updated (zoom or pan funcionalities). I'm using the Map.ExtentChanged Event, but Sometimes the Image is shot before the Whole map is Shown. Is there any event or property that could show me the exact moment that the map finishes rendering? MyMap.ExtentChanged += (s, e) => { WriteableBitmap imagem = new WriteableBitmap(MyMap, null); mapImagePreview.Source = imagem; mapImagePreview.HorizontalAlignment = HorizontalAlignment.Center; mapImagePreview.VerticalAlignment = VerticalAlignment.Center; mapImagePreview.Stretch = Stretch.Uniform; imagem.Render(MyMap, null); }; ...

Hi, In my project, I have a map that needs to be inside a ScrollBar. My problem is that when I do so, I lose the Pan functionality of the map. I really must find some way to make the pan work, and i also must give the user the possibility to scrolling possibility on the window (a ChildWindow) so it can see the whole content of the page. ...

Hi, I'm doing a Silvelight application, and in it I need to get the info about the legend of the map, so I can add it on a printing funtionality. I know that the esri legend class gets it from the rest service (something like http://server/ArcGIS/rest/services/Folder/Service/MapServer/legend) but i don't know how to get this list myself, and i need to get a specific list of items from it (the ones been used - the info about what's shown on the map - at the moment the user clicks the print button). Does anyone know how to do it? ... View more

Hi, I'm making a silverlight application with the ArcGIS API for Silverlight, and in it i need to do online edition to mark constructions, and i'm having a lot of trouble with a specific case. I need to insert a mark by receiving the X,Y coordinates. I tryed adding at the graphics list on the feature layer, with it auto and manual saving, and didn't work. My second attempt was with the Editor class, but the add command requires that the user click on the map, and I can't bypass it, no matter what i try. I need to know if there's any other way to add map points at the feature layers and save it. ... View more
