Bing AerialWithLabels not rendering on accelerated Layers collection

AaronMorrisett

I have a bing layer working on accelerated layers, however we have noticed that the LayerStyle = AerialWithLabels will only render when it is added to the regular layer collection. the section of code that switches the layerstyle is simple and looks like the following.

   switch (bingType)                 {                     case (BingMapType.Street):                         thisType = TileLayer.LayerType.Road;                         break;                     case (BingMapType.Satellite):                         thisType = TileLayer.LayerType.Aerial;                         break;                     case (BingMapType.Hybrid):                         thisType = TileLayer.LayerType.AerialWithLabels;                         break;                 }                                 _bingLayer = new TileLayer { LayerStyle = thisType, ServerType = ServerType.Production, Token = _config.BingKey, Visible = _baseLayerVisibility, ShowLegend = false };

By this point the _bingLayer has already been added to the acceleratedLayers collection. Note that switching to aerial and road styles render perfectly.

Any suggestions?

Aaron

Hi,

Apologies I didn't remember that it was a bug in the v1.0 release of the SDK (build 396 of the ESRI.ArcGIS.Client.* dlls). It is fixed for the next release.

Cheers

Here is the entire section of code I am using that works if I use pre-release .dll's but not with release .dll's.

Are you using the WPF pre-release .dll's that are version 3.0.0.318 or the release version 3.0.0.396.

In the pre-release version I can get all three types of the bing map to display correctly. However if I use the release dll's I can only get road and aerial to work.

Aaron

Hi,

Just new'ing the layer probably won't trigger the layer initialization - to confirm you could try calling Initialize() on the layer then adding it to the map.

Cheers

Thanks for the reply,
The only difference I notice between our code is that you are removing it from the collection and re-adding it when you switch layer style. I'll give this a shot and see if it seems to help.

Hi,

Unfortunately I have not been able to reproduce the problem. Here's the code I'm trying - it should be approximately similar to yours:

Code:

        TileLayer _bingLayer;

        private void BingRadioButton_Checked(object sender, RoutedEventArgs e)
        {
            string layerTypeTag = (string)((RadioButton)sender).Tag;

            ESRI.ArcGIS.Client.Bing.TileLayer.LayerType layerType = null;

            switch (layerTypeTag)
            {
                case ("Road"):
                    layerType = TileLayer.LayerType.Road;
                    break;
                case ("Aerial"):
                    layerType = TileLayer.LayerType.Aerial;
                    break;
                case ("AerialWithLabels"):
                    layerType = TileLayer.LayerType.AerialWithLabels;
                    break;
            }

            if (_map.Layers["_bingLayer"] != null)
            {
                _acceleratedDisplayLayersGroup.ChildLayers.Remove(_bingLayer);
            }

            _bingLayer = new TileLayer 
            { 
                ID="_bingLayer",
                LayerStyle = layerType, 
                ServerType = ServerType.Production,
                Token = "<ENTER TOKEN HERE>", 
                Visible = true, 
                ShowLegend = false 
            };

          _acceleratedDisplayLayersGroup.ChildLayers.Add(_bingLayer);
        }

XAML:

<Grid>
    <esri:Map x:Name="_map" UseAcceleratedDisplay="False">
        <esri:AcceleratedDisplayLayers x:Name="_acceleratedDisplayLayersGroup">

        </esri:AcceleratedDisplayLayers>
    </esri:Map>
    <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
        <RadioButton x:Name="RoadRadioButton" Checked="BingRadioButton_Checked"
                        Tag="Road" IsChecked="true" Margin="5,0,0,0" 
                        GroupName="Layers" Content="Road" />
        <RadioButton x:Name="AerialRadioButton" Checked="BingRadioButton_Checked"
                        Tag="Aerial" Margin="5,0,0,0"  
                        GroupName="Layers" Content="Aerial" />
        <RadioButton x:Name="AerialWithLabelsRadioButton" Checked="BingRadioButton_Checked" 
                        Tag="AerialWithLabels" Margin="5,0,0,0" 
                        GroupName="Layers" Content="Aerial - Labels"/>
    </StackPanel>
</Grid>

Cheers

Mike
