Bing TileLayer Silverlight 4

KadeSmith

When I try adding a Bing TileLayer to a map in SL4, I get the following error message:

A value of type 'TileLayer' cannot be added to a collection or dictionary of type 'LayerCollection'.

Exact code in SL3 is working fine. Here are portions of my code.

xmlns:bing="clr-namespace:ESRI.ArcGIS.Client.Bing;assembly=ESRI.ArcGIS.Client.Bing"

<esri:Map x:Name="Map" IsLogoVisible="False" Loaded="Map_Loaded" Grid.Row="1">
            <esri:Map.Extent>
                <esriGeometry:Envelope XMin="-9860192.874701" YMin="3536523.562187" XMax="-9454281.630124" YMax="4181859.017432">
                    <esriGeometry:Envelope.SpatialReference>
                        <esriGeometry:SpatialReference WKID="102100" />
                    </esriGeometry:Envelope.SpatialReference>
                </esriGeometry:Envelope>
            </esri:Map.Extent>

            <esri:Map.Layers>
                <bing:TileLayer ID="BingLayer" LayerStyle="Road" Visible="True" />
                <esri:ArcGISTiledMapServiceLayer ID="Street Map" Url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" Opacity=".5" />
                <esri:GraphicsLayer ID="MarkupDrawingLayer" />
            </esri:Map.Layers>

        </esri:Map>

Thanks Dominique

private void RadioButtonOff_Click(object sender, RoutedEventArgs e)
        {
            ESRI.ArcGIS.Client.Bing.TileLayer tileLayer = MyMap.Layers["BingLayer"] as TileLayer;
            tileLayer.Visible = false;
        }

        private void RadioButton_Click(object sender, RoutedEventArgs e)
        {
            ESRI.ArcGIS.Client.Bing.TileLayer tileLayer = MyMap.Layers["BingLayer"] as TileLayer;
            string layerTypeTag = (string)((RadioButton)sender).Tag;
            TileLayer.LayerType newLayerType = (TileLayer.LayerType)System.Enum.Parse(typeof(TileLayer.LayerType), layerTypeTag, true);
            tileLayer.LayerStyle = newLayerType;

            if (tileLayer.Visible == false) 
            {
            tileLayer.Visible = true;
            }
 
        }

I tried that just after you posted and it works, rather than doing the code in xaml.

I assume I would have to contact microsoft or track the usage manually to find out if Bing Maps is still counting transactions because I am only changing the visibility of the tile layer, not removing the actual basemap.

I did that in one application, so I give you the code (XAML):

  
<!-- Base Map Switcher -->
<Border x:Name="BaseMapSwitcher" Style="{StaticResource CommonBorder}" VerticalAlignment="Top" HorizontalAlignment="Right" Margin="5">
 <StackPanel Orientation="Horizontal" Margin="5">
   <RadioButton Content="No BaseMap" ToolTipService.ToolTip="No base map" GroupName="BaseLayer" Margin="5,0,0,0" Foreground="White" FontSize="11" >
     <i:Interaction.Triggers>
       <i:EventTrigger EventName="Checked">
         <actions:SetLayerVisibilityAction TargetName="Map" LayerID="BaseLayer" Visible="False"/>
       </i:EventTrigger>
     </i:Interaction.Triggers>
   </RadioButton>
   <RadioButton Content="Streets" IsChecked="True" ToolTipService.ToolTip="Worldwide Street Map" GroupName="BaseLayer" Margin="5,0,0,0" Foreground="White" FontSize="11" >
     <i:Interaction.Triggers>
       <i:EventTrigger EventName="Checked">
         <actions:SetLayerUrlAction TargetName="Map" LayerID="BaseLayer" Url="http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer"/>
         <actions:SetLayerVisibilityAction TargetName="Map" LayerID="BaseLayer" Visible="True"/>
       </i:EventTrigger>
     </i:Interaction.Triggers>
   </RadioButton>
.......

As an ArcGISMapServiceLayer doesn't accept an empty Url, I switch the visibility On/Off.

One more question, using the sample code found on the ESRI Silverlight Samples page, is it possible to remove the bing maps tile layer completely? Ive added a 4th button titled 'None', and to cut down on imagery costs when they are not necessary, I would like to not show any Bing Tiles when that option is checked. Thanks again.

TylerMunn

It works now, great! Thanks a lot for the help.

DominiqueBroux

I already got this error when there is a mismatch in the ESRI.ArcGIS.Client and ESRI.ArcGIS.Client.bing references (not the same version number).

Verify the versions of these 2 packages and might worth the try to remove and to add again the references.

TylerMunn

kadesmith - were you able to resolve your issue?

Morten, would you have any idea aside from your earlier suggestion? I have my ECP code for Bing Imagery from ESRI and am really hoping to have it up & running asap.

Thanks

TylerMunn

Morten,

I have modified my code and am still getting the same message as kadesmith. Even taking the code example from http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#BingImagery where

<bing: TileLayer / > falls only within <esri:map > </esri:map>, the error still appears.

Microsoft fixed a few things in the XAML parser that is causing this. Either remove the <esri:Map.Layers> part (layer collection is implied), or add a <esri:LayerCollection> around the layers:

<esri:Map >
  <esri:Map.Layers>
    <esri:LayerCollection>
      <bing:TileLayer />
      <esri:ArcGISTiledMapServiceLayer /> 
      <esri:GraphicsLayer />
    </esri:LayerCollection>
  </esri:Map.Layers>
</esri:Map>

<esri:Map >
  <bing:TileLayer />
  <esri:ArcGISTiledMapServiceLayer /> 
  <esri:GraphicsLayer />
</esri:Map>

Difference is that the first one replaces the existing layer collection, the other one adds to it, but the result is the same.

TylerMunn

I'm getting the same issue, however I haven't tried it in SL3. Unsure of where to go from there
