slider inside legenda

MarcoRosa · ‎01-26-2011

Hi , hi have this case:
a arcgisdynamicmapservicelayer whitin of them just 1 layer. I observed that if
LayerItemsMode = flat the slider of opacity doesn't more visible instead if LayerItemsMode is Tree is visible.
Is there a way to view the slider in both case ? or workaround about this ?

thank's very much

the code is the following:

          <esri:Legend x:Name="legenda" Map="{Binding ElementName=Map}"
                         LayerItemsMode="Flat"
                         ShowOnlyVisibleLayers="False"
                         Refreshed="Legend_Refreshed">

                <esri:Legend.MapLayerTemplate>
                    <DataTemplate>
                          <StackPanel Orientation="Horizontal">

                            <Grid x:Name="BusyIndicator" Background="Transparent" Margin="3,0"
       HorizontalAlignment="Left" VerticalAlignment="Center" RenderTransformOrigin="0.5,0.5" >
                                <Grid.Triggers>
                                    <EventTrigger RoutedEvent="Grid.Loaded">
                                        <EventTrigger.Actions>
                                            <BeginStoryboard>
                                                <Storyboard>
                                                    <DoubleAnimation Duration="0:0:1" RepeatBehavior="Forever" To="360" Storyboard.TargetName="BusyIndicator"
                     Storyboard.TargetProperty="(UIElement.RenderTransform).(RotateTransform.Angle)" />
                                                </Storyboard>
                                            </BeginStoryboard>
                                        </EventTrigger.Actions>
                                    </EventTrigger>
                                </Grid.Triggers>

                                <Grid.RenderTransform>
                                    <RotateTransform />
                                </Grid.RenderTransform>
                                <Ellipse Fill="#1E525252" Margin="11,2,11,20" Width="2" Height="2"/>

                                <Ellipse Fill="#FF525252" Height="6" Width="6" VerticalAlignment="Bottom" Margin="9,0" />
                            </Grid>
                            <CheckBox Content="{Binding Label}"

                    </DataTemplate>
                </esri:Legend.LayerTemplate>

            </esri:Legend>

You can add the same slider to the layerTemplate:

 
<esri:Legend.LayerTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox x:Name="CheckBoxLayers" Content="{Binding Label}"
IsChecked="{Binding IsEnabled, Mode=TwoWay}"
IsEnabled="{Binding IsInScaleRange}" Checked="CheckBox_Checked"
Unchecked="CheckBox_Unchecked">
</CheckBox>
<Slider Maximum="1" Value="{Binding Layer.Opacity, Mode=TwoWay}" Width="50" />
</StackPanel>
</DataTemplate>
</esri:Legend.LayerTemplate>

This is obsiously not modifying the opacity of the sublayer (that's not possible) but of the main service layer. But as you have only one sublayer in your service, the result is the same.
