Question

I have a INotifyPropertyChanged derived class with a Volume property (float, 0.0f – 1.0f) that gets set on a fixed frequency (say 30fps).
I’d like to draw a tiny volumebar displaying this in my window.
I don’t want to use a normal databound progressbar, I’d prefer something simpler (and faster :)).

Is there a proper way to simply draw a filled rectangle where the width is bound to my Volume property ?

You could use a rectangle and a scale transform. I doubt it would be significantly faster than re-templating a ProgressBar though.

    <Rectangle Width="200" Height="40" Fill="Orange">
        <Rectangle.RenderTransform>
            <ScaleTransform ScaleX="{Binding Volume}" />
        </Rectangle.RenderTransform>
    </Rectangle>
