Hi -

 I am trying to get an event to fire via ViewModel when navigating away from a page and I did the following...

<navigation:Page xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation xmlns:this="clr-namespace:DataOnline.RAM.DOLWebApp"  xmlns:csla ="clr-namespace:Csla.Xaml;assembly=Csla.Xaml" xmlns:controlsToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit" xmlns:navigation ="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" x:Class="DataOnline.RAM.DOLWebApp.Views.Systems" x:Name="SystemPage" >

<navigation:Page.Resources>

        <this:StatusViewModel x:Key="mySystemViewModel"/>

</navigation:Page.Resources>

<Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource mySystemViewModel }}">

<csla:TriggerAction x:Name="StopTimerTrigger" MethodName="KillTimer" TriggerEvent="NavigatedFrom" TargetControl="{Binding ElementName =SystemPage}"/>

</Grid>

</navigation:Page>

public void KillTimer(object sender, Csla.Xaml.ExecuteEventArgs e)

{

}

The event “KillTimer” doesn’t get fired and I am wondering why.. Any ideas??

 Thanks
