Navigation Control doesn't show slider

AndrewPurkis

Hi

I'm having problems with the navigation control, when using a local map package.  The map loads correctly, but the navigation control doesn't display a zoom slider (see attached [ATTACH=CONFIG]21551[/ATTACH]).

I've tried this in code behind (preferred solution) and xaml.

XAML:
<Window x:Class="navtest2.MainWindow"
    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" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    d:DesignWidth="337" SizeToContent="WidthAndHeight"
    d:DesignHeight="287" mc:Ignorable="d"
    Loaded="Window_Loaded">
<Grid x:Name="LayoutRoot" >
  <Grid.Resources>
   <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/>
  </Grid.Resources>
  <esri:Map x:Name="MyMap" WrapAround="True"
       Extent="-15000000,2000000,-7000000,8000000"
       Background="#FFE3E3E3" MinimumResolution="2445.98490512499">
   <esri:ArcGISLocalDynamicMapServiceLayer Path="./USCitiesStates.mpk"/>
  </esri:Map>
  <esri:Navigation Margin="5" HorizontalAlignment="Left"
           VerticalAlignment="Bottom"
                     Map="{Binding ElementName=MyMap}"  />
</Grid>
</Window>

C# Behind Code:
   LocalMapService localMapService = new LocalMapService()
    {
    Path = "./USCitiesStates.mpk",
    MaxRecords = 100000
    };
   localMapService.StartAsync(localService =>
    {
    if (localService.Error != null)
     return;
    ArcGISLocalDynamicMapServiceLayer layer = new ArcGISLocalDynamicMapServiceLayer(localMapService);
    MyMap.Layers.Add(layer);
    });

Any help would be appreciated.

Thanks

The zoom slider will only be displayed if the Map.MinimumResolution and Map.MaximumResolution resolution on the Map control have been defined. If a ESRI.ArcGIS.Client.TiledMapServiceLayer is present in the Map's layer collection, in most cases the minimum and maximum resolution will be set for you. If a Map only contains ESRI.ArcGIS.Client.DynamicLayer, you must set the minimum and maximum resolution explicitly.
