Open table of contents with layers expanded

Question

Is there a way to open the Table of contents [out of the box] that comes with the viewer to open the layers with the list expanded ?

I have written a behavior that expands the Map Contents on load Also play around with the settings for Tools -> Configure Controls -> Map Contents -> Check Expand Layers on Add Behavior code: using System.ComponentModel.Composition; using System.Windows; using System.Windows.Controls; using System.Windows.Interactivity; using System.Windows.Media.Animation; using ESRI.ArcGIS.Client; using ESRI.ArcGIS.Client.Extensibility; namespace MyBehaviour.Panels { [Export(typeof(Behavior))] [DisplayName("Show Hide Map Content Panel")] [Category("Behaviors")] [Description("Display Map Content Panel on load")] public class MapContentBehavior : Behavior { #region Behavior Overrides protected override void OnAttached() { base.OnAttached(); MapApplication.Current.Map.Loaded += Map_Loaded; } protected override void OnDetaching() { MapApplication.Current.Map.Loaded -= Map_Loaded; } #endregion #region Events void Map_Loaded(object sender, RoutedEventArgs e) { // Find SidePanel TabControl sidePanel = MapApplication.Current.FindObjectInLayout("SidePanelContainer") as TabControl; if (sidePanel != null) { TabItem tab = null; int customControlPanelIndex = -1; // Get the index of the tab in the side panel that contains our control for (int i = 0; i < sidePanel.Items.Count; i++) { tab = sidePanel.Items as TabItem; if (tab.Name == "MapContentsTabItem") { customControlPanelIndex = i; break; } } Storyboard storyBoard; // Check whether the control needs to be shown or hidden if (sidePanel.SelectedIndex != customControlPanelIndex || sidePanel.Visibility == Visibility.Collapsed) { // Update the side panel's selected index to set the tab containing the control to be the selected one. sidePanel.SelectedIndex = customControlPanelIndex; // Check whether the side panel is visible at all. If not, it needs to be shown if (sidePanel.Visibility == Visibility.Collapsed) { // Check whether the side panel has a visual state called Show. If so, we'll show the side // panel by invoking the storyboard from this state. storyBoard = VisualStateManagerHelper.FindVisualStateStoryboard(sidePanel, null, "Show", true); if (storyBoard != null) storyBoard.Begin(); else // The side panel does not have a Show state, so set the panel's visibility directly sidePanel.Visibility = Visibility.Visible; } } else { // The toggle button is being clicked when the control is already visible. So the click should hide it. // Check whether the side panel has a visual state called Hide. If so, we'll hide the side // panel by invoking the storyboard from this state. storyBoard = VisualStateManagerHelper.FindVisualStateStoryboard(sidePanel, null, "Hide", true); if (storyBoard != null) storyBoard.Begin(); else // The side panel does not have a Hide state, so set the panel's visibility directly sidePanel.Visibility = Visibility.Collapsed; } } } #endregion } }
