Timer Stop the others animations

Hi,

I have a timer for execute a dinamyc storyboard in my page.xaml, but when this storyboard is executing, I can't do anothers actions in my page (for example if I am writing in a textbox when the timer_tick, the writer stop).

 

In my xaml I have:

 

 <vsm:VisualStateGroup x:Name="EstadoImagenes">
                <vsm:VisualStateGroup.Transitions>
                    <vsm:VisualTransition GeneratedDuration="00:00:02"/>
                </vsm:VisualStateGroup.Transitions>
                <vsm:VisualState x:Name="Estado1"/>
                <vsm:VisualState x:Name="Estado2">
                    <Storyboard>
                        <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="foto" Storyboard.TargetProperty="(UIElement.Opacity)">
                            <SplineDoubleKeyFrame KeyTime="00:00:00" Value="0"/>
                        </DoubleAnimationUsingKeyFrames>
                        <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="foto2" Storyboard.TargetProperty="(UIElement.Opacity)">
                            <SplineDoubleKeyFrame KeyTime="00:00:00" Value="1"/>
                        </DoubleAnimationUsingKeyFrames>
                    </Storyboard>
                </vsm:VisualState>
            </vsm:VisualStateGroup>

....

<TextBox Height="Auto" Cursor="Hand" HorizontalAlignment="Right" Margin="0,0,20,0" x:Name="terminos" VerticalAlignment="Center" Width="Auto" FontFamily="Verdana" FontSize="10"   TextAlignment="Right" />

  

And In the codebehind

 

Dim timer1 As System.Windows.Threading.DispatcherTimer
    Dim timerControl As System.Windows.Threading.DispatcherTimer

 Public Sub New()
        InitializeComponent()

        'Creamos el temporizador que camiará las imágenes
        timer1 = New System.Windows.Threading.DispatcherTimer()
        timer1.Interval = TimeSpan.FromSeconds(5)
        timerControl = New System.Windows.Threading.DispatcherTimer()
        timerControl.Interval = TimeSpan.FromSeconds(2)
        timerControl.Stop()

        AddHandler timer1.Tick, AddressOf Timer_Tick
        AddHandler timerControl.Tick, AddressOf EfectoImagen_Completed
       

        timer1.Start()
End sub

 Private Sub Timer_Tick()
        timer1.Stop()
        CambiarImagen()
    End Sub
    Private Sub CambiarImagen()
        If currentFoto = 1 Then
            VisualStateManager.GoToState(Me, "Estado2", True)
        Else
            VisualStateManager.GoToState(Me, "Estado1", True)
        End If
        timerControl.Start()
    End Sub

    Private Sub EfectoImagen_Completed()
        timerControl.Stop()
        ActualizarImagen()
        timer1.Start()
    End Sub

    Private Sub ActualizarImagen()
        If i >= images.Count - 1 Then
            i = 0
        Else
            If currentFoto = 1 Then
                foto.Source = New BitmapImage(New Uri("../" & _SkinDir & "Carrusel/" & System.IO.Path.GetFileName(images(i)), UriKind.RelativeOrAbsolute))
                currentFoto = 2
            Else
                foto2.Source = New BitmapImage(New Uri("../" & _SkinDir & "Carrusel/" & System.IO.Path.GetFileName(images(i)), UriKind.RelativeOrAbsolute))
                currentFoto = 1
            End If
            i += 1
        End If
    End Sub

  

I'm using two timers because, I haven't get use Completed Event for "EstadoImagenes".

Can I solved this?

 

Excuse for me English.

 

Best Regards.

I'm struggling with the description a little so I may be answering the wrong question.

 If you want to disable controls while the animation is running you could try to do this within the animation by using an ObjectKeyFrame to set the Enabled property of the controls to False at the start of the storyboard and back to True at the end of the storyboard.
