MVVM Passing EventArgs As Command Parameter

I'm using Microsoft Expression Blend 4
I have a Browser ..,

[ XAML ] ConnectionView " Empty Code Behind "

 <WebBrowser local:AttachedProperties.BrowserSource="{Binding Source}"> <i:Interaction.Triggers> <i:EventTrigger> <i:InvokeCommandAction Command="{Binding LoadedEvent}"/> </i:EventTrigger> <i:EventTrigger EventName="Navigated"> <i:InvokeCommandAction Command="{Binding NavigatedEvent}" CommandParameter="??????"/> </i:EventTrigger> </i:Interaction.Triggers> </WebBrowser>

[ C# ] ConnectionViewModel Class

public class ConnectionViewModel : ViewModelBase { public string Source { get { return Get<string> ( "Source" ); } set { Set ( "Source" , value ); } } public void Execute_ExitCommand ( ) { Application . Current . Shutdown ( ); } public void Execute_LoadedEvent ( ) { MessageBox . Show ( "___Execute_LoadedEvent___" ); Source = ...... ; } public void Execute_NavigatedEvent ( ) { MessageBox . Show ( "___Execute_NavigatedEvent___" ); } }

[ C# ] ViewModelBase class Here

Finally :
Binding with commands works well and MessageBoxes shown

My Question :
How to pass NavigationEventArgs as Command Parameters when Navigated Event occurs ?
