Does anyone know how you would remove legenditems from the legend without removing layeritems of maplayeritems? I'm trying to make a TOC for layers and a separate Legend swatch for my app, I've succesfully made a listbox populated with legenditems only, but cant seem to find a way to keep the legenditems from keeping at the very least a blank placeholder.
<toolkit:Legend x:Name="theLegend" Map="{Binding ElementName=TabletMap}" Grid.Row="1" LayerItemsMode="Tree" ShowOnlyVisibleLayers="False" LayerIDs="ESRI Map Services, PESData" Refreshed="Legend_Refreshed" >
<toolkit:Legend.MapLayerTemplate>
<DataTemplate >
<StackPanel >
<TextBlock Text="{Binding Label}" VerticalAlignment="Center" HorizontalAlignment="Left" FontWeight="Bold" Foreground="#FF32475D" FontSize="12" />
<Slider Maximum="1" Value="{Binding Layer.Opacity, Mode=TwoWay}" Width="180" HorizontalAlignment="Right" />
</StackPanel>
</DataTemplate>
</toolkit:Legend.MapLayerTemplate>
<toolkit:Legend.LayerTemplate>
<DataTemplate >
<StackPanel Orientation="Horizontal">
<CheckBox Content="{Binding Label}" IsChecked="{Binding IsEnabled, Mode=TwoWay}"/>
</StackPanel>
</DataTemplate>
</toolkit:Legend.LayerTemplate>
<esri:Legend.LegendItemTemplate>
<DataTemplate>
<Rectangle Visibility="Collapsed" />
</DataTemplate>
</esri:Legend.LegendItemTemplate>
</toolkit:Legend>
private void Legend_Refreshed(object sender, Legend.RefreshedEventArgs e)
{
LayerItemViewModel removeLayerItemVM = null;
if (e.LayerItem.LayerItems != null)
{
foreach (LayerItemViewModel layerItemVM in e.LayerItem.LayerItems)
{
if (layerItemVM.LayerItems != null)
foreach (LayerItemViewModel sublayerItemVM in layerItemVM.LayerItems)
sublayerItemVM.IsVIsible = false;
}
if (removeLayerItemVM != null)
e.LayerItem.LayerItems.Remove(removeLayerItemVM);
}
else
{
e.LayerItem.IsExpanded = false;
}
}
It throws the error "Error 1 'ESRI.ArcGIS.Client.Toolkit.Primitives.LayerItemViewModel' does not contain a definition for 'IsVIsible' and no extension method 'IsVIsible' accepting a first argument of type 'ESRI.ArcGIS.Client.Toolkit.Primitives.LayerItemViewModel' could be found (are you missing a using directive or an assembly reference?)
