i'm new to wpf and i'm try to learn something.
My problem is : i need to bind all that i want to a looping animation...

Example:

```
<Window x:Class="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<StackPanel>
    <Slider Visibility="Hidden"  Minimum="0" Maximum="100" Height="22" Margin="73,40,105,0" Name="Slider1" VerticalAlignment="Top" Value="0">
        <Slider.Triggers>
        <EventTrigger RoutedEvent="Slider.Loaded">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation
                        Storyboard.TargetName="Slider1" 
                        Storyboard.TargetProperty="Value"
                        From="0" To="100" Duration="0:0:5" 
                        AutoReverse="True" RepeatBehavior="Forever" />
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
            </Slider.Triggers>
    </Slider>
    <Slider Minimum="0" Maximum="100" Height="22" Margin="72,98,106,0" Name="Slider2" VerticalAlignment="Top" Value="{Binding ElementName=Slider1, Path=Value}"/>
    <Button Width="{Binding ElementName=Slider1, Path=Value}"></Button>
</StackPanel>

```

Slider1 is hidden and act as a Source for Slider2 and ButtonWidth.
Like a standalone oscillator.
I need a way to eliminate slider1 and bind directly to a standalone animation that loops.
It is possible?
Thanks in advance :)
