TOC Questions

Hi

I created following TOC from the Silverlight Samples Page:

<ListBox ItemsSource="{Binding ElementName=map, Path=Layers.[0].Layers}" MinWidth="330" Margin="5" FontWeight="Normal">
                                    <ListBox.ItemsPanel>
                                        <ItemsPanelTemplate VirtualizingStackPanel.VirtualizationMode="Standard" />
                                    </ListBox.ItemsPanel>
                                    <ListBox.ItemTemplate>
                                        <DataTemplate>
                                            <StackPanel Orientation="Horizontal">
                                                <CheckBox Margin="2"
                                                Name="WasserhaltungMXD"
                                                Content="{Binding Name}" Tag="{Binding ID}"
                                                ClickMode="Press"
                                                Click="CheckBox_Click2"
                                                IsChecked="{Binding DefaultVisibility}" />
                                            </StackPanel>
                                        </DataTemplate>
                            </ListBox.ItemTemplate>

Now i have two Question:

1. Is it possible to group the TOC by individual Groups, so that the List box consists of some kind of TreeView, and not all Sublayer-Checkboxes are shown at once??

2. Is it possible to create a Slider to change the Opacity of the Sublayers, like one can do it with the Layers??

It is possible but it needs some developments to create the hierarchical data.
From version 2.1, a legend/TOC control will be provided.

2. Is it possible to create a Slider to change the Opacity of the Sublayers, like one can do it with the Layers??

No that's not possible. The opacity of sublayers is defined when publishing the service and can't be changed by the REST API.

I have not downloaded 2.1 but I did read through the "What's New" and I did not see any mention of a legend/TOC control being provided.

Did this happen "From version 2.1, a legend/TOC control will be provided."

It's not available in the beta, but should be in the RC.
