Getting the value of my Custom DependencyProperty?

Hi,

I create a DependencyProperty for my WPF RibbonTab:

public static class ExecuteViewParameter
{
	// Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
	public static readonly DependencyProperty ExecuteViewParametersProperty =
		DependencyProperty.RegisterAttached("ExecuteViewParameters", typeof(ExecuteViewType), typeof(ExecuteViewParameter), new PropertyMetadata(ExecuteViewType.Hebrew));

	public static void SetExecuteViewParameters(DependencyObject element, ExecuteViewType value)
	{
		element.SetValue(ExecuteViewParametersProperty, value);
	}
	public static ExecuteViewType GetExecuteViewParameters(DependencyObject element)
	{
		return (ExecuteViewType)element.GetValue(ExecuteViewParametersProperty);
	}
}

XAML:

<RibbonTab Header="Greek Table" infDependencyObjects:ExecuteViewParameter.ExecuteViewParameters="{Binding Source={x:Static infModels:ExecuteViewType.GreekTable}}" ContextualTabGroupHeader="Table Workspace" Style="{StaticResource TableGreekContextualTabVisibility}"><RibbonGroup Name="UpdateGreekTable" Header="Greek Table"><RibbonButton 
			Label="Update"
			SmallImageSource="/Natsar.Common;component/Resources/Green.png" LargeImageSource="/Natsar.Common;component/Resources/GreenLarge.png" 
			IsEnabled="{Binding Path=PropertiesService.IsEnabledUpdateGreekTableCommand, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}"
			infDependencyObjects:ViewNamesParameter.ViewParameters="{Binding Source={x:Static inf:ViewNames.GreekTableView}}"
			infDependencyObjects:ActiveViewNamesParameter.ActiveViewParameters="{Binding Source={x:Static inf:ActiveViewNames.WritingsTableManagerView}}"
			infDependencyObjects:ExecuteViewParameter.ExecuteViewParameters="{Binding Source={x:Static infModels:ExecuteViewType.GreekTable}}"
			Style="{StaticResource UpdateTableCommand}"/><RibbonButton 
			Label="Create"
			SmallImageSource="/Natsar.Common;component/Resources/Yellow.png" 
			IsEnabled="{Binding Path=PropertiesService.IsEnabledCreateGreekTableContentCommand, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}"
			infDependencyObjects:ViewNamesParameter.ViewParameters="{Binding Source={x:Static inf:ViewNames.GreekTableView}}"
			infDependencyObjects:ActiveViewNamesParameter.ActiveViewParameters="{Binding Source={x:Static inf:ActiveViewNames.WritingsTableManagerView}}"
			infDependencyObjects:ExecuteViewParameter.ExecuteViewParameters="{Binding Source={x:Static infModels:ExecuteViewType.GreekTable}}"
			Style="{StaticResource CreateTableCommand}"/></RibbonGroup></RibbonTab>

In my code I'm capturing the SelectionChanged event:

public void OnRibbonSelectionChangedEvent(object sender, SelectionChangedEventArgs args)
{
	try
	{
		RibbonTab tab = (sender as Ribbon).SelectedItem as RibbonTab;
		if (tab is RibbonTab && tab != null)
		{
			this.eventAggregator.GetEvent<MessageUpdateEvent>().Publish(new MessageUpdateEvent { Message = "You selected " + tab.ToString() });
		}
	}
	catch (Exception msg)
	{
		.....
	}
}

How do I get the DependencyProperty value?

Thanks!...

Code is like a box of chocolates!...
