Slider control use

Can anyone explain to me how I'm supposed to use the slider to actually
connect it to another control or objects property? The Windows SDK
sample and the Sells book only show how to place the Slider on your
form, but not actually use it to do anything! I'd like to use a slider
to resize my window...

Thanks,
Jason

Ok, I think I originally misunderstood, it's really the property that
you want to set that is hooked up to the value of the slider. First you
handle the slider's ValueChanged event in your XAML:

<Slider ValueChanged="OnSliderValueChanged" />


In the code behind file, implement that method to set your property to
the current value of the slider:

public void OnSliderValueChanged(object sender,
RoutedPropertyChangedEventArgs<double> e)
{
Console.WriteLine(scaler.Value);
Height = scaler.Value; // this could be any other property
}



However, is this really necessary? I'd love to see some syntactic sugar
that would just directly allow you to directly hook an objects property
to the slider. It's a pain to have to put the event handling code in
here. I can't think of a scenario where you use a slider where you
wouldn't be handling the ValueChanged event, so why not provide a shortcut?

This Slider controls the Width of the Button:
<Grid>

<Button Name="btn" Width="50" Height="50">Test</Button>

<Slider Value="{Binding ElementName=btn, Path=Width}" Minimum="50"
Maximum="300"/>

</Grid>

Hope that helps you get started,
