I think I figured this out. I needed to set up an event handler to set my Diaolog to null when hidewindow was fired. Here is my code in case anyone finds it useful or wants to show me there is a better way to handle. [Export(typeof(ICommand))]     [DisplayName("Hail Analysis Tool")]     public class AnalysisTool : ICommand     {         private MyAnalysisDialog AnalysisDialog = null;         // Event Declaration         public event EventHandler hideDialog;                #region ICommand members         public void Execute(object parameter)         {             // Create a new Dialog if one has not already been created             //AnalysisDialog = AnalysisDialog ?? new MyAnalysisDialog();             hideDialog += new EventHandler(HideHandler);             if (AnalysisDialog != null)             {                 MapApplication.Current.HideWindow(AnalysisDialog);                                             }             else             {                 AnalysisDialog = new MyAnalysisDialog();                                 MapApplication.Current.ShowWindow("Hail Analysis", AnalysisDialog, false, null,HideHandler);             }                      }          public void HideHandler(object sender, EventArgs e)         {             AnalysisDialog = null;             hideDialog -= new EventHandler(HideHandler);         }          public bool CanExecute(object parameter)         {             // Return true so that the command can always be executed             return true;         }          public event EventHandler CanExecuteChanged;          #endregion     } ...

I am pretty sure you will need to create a custom layout to accomplish this. I did something close to what you are talking about but the transparency slider i created sits outside Map Content Control. Here is the transparency Slider I used in my custom layout based on the Accordian Layout. Edit* - I forgot to mention that i have this collapsed by defualt and use a custom add-in to toggle visibility. <!--Transparency Slider-->                  <Grid x:Name="TransparencyBox" HorizontalAlignment="Left" VerticalAlignment="Top" Width="190" Height="80" Margin="5" Visibility="Collapsed" Grid.Column="1">                       <Border x:Name="TransparencyContainer" Style="{StaticResource GlassyBorder}" Padding="3,3,3,3" Opacity="1">                          <!--<Border.Effect>                              <DropShadowEffect />                          </Border.Effect>-->       <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5">                         <Grid.RowDefinitions>                             <RowDefinition Height="Auto"/>                             <RowDefinition/>                         </Grid.RowDefinitions>                         <Border BorderThickness="0" Margin="0" VerticalAlignment="Stretch"                              Background="{StaticResource AccentTextColorBrush}" Opacity="0.2"                              CornerRadius="3,3,0,0">                         </Border>                         <TextBlock TextWrapping="Wrap" Foreground="{StaticResource AccentTextColorBrush}"                                  Text="Layer Transparency"                                                                              FontSize="12" FontWeight="Bold"                                 Margin="5,2,2,2"/>                                <Button  Margin="0,0,0,0"  Opacity="1" Grid.Row="0" HorizontalAlignment="Right"  VerticalAlignment="Top" Width="23" Visibility="{Binding Visibility, ElementName=TransparencyBox}" Style="{StaticResource CloseButtonStyle}" Background="{StaticResource AccentColorBrush}" BorderBrush="{StaticResource AccentColorBrush}" Foreground="{StaticResource AccentTextColorBrush}" >        <i:Interaction.Triggers>         <i:EventTrigger EventName="Click">          <ei:ChangePropertyAction TargetObject="{Binding ElementName=TransparencyBox}" PropertyName="Visibility">           <ei:ChangePropertyAction.Value>            <Visibility>Collapsed</Visibility>          </ei:ChangePropertyAction.Value>          </ei:ChangePropertyAction>         </i:EventTrigger>        </i:Interaction.Triggers>       </Button>                                                         <Slider  Grid.Row="1" Height="23" Width="150" Name="slider1" HorizontalAlignment="Center" Minimum="0" Maximum="1" Value="{Binding Path=SelectedLayer.Opacity, Mode=TwoWay, Source={StaticResource MapApplication}}" IsDirectionReversed="False" />       </Grid>                      </Border>                         </Grid> ...
