    I've a problem with the SliceStyleSelector. Actually i couldn't find a decent example. I'm struggling with the piechart and binding custom object which includes Color property in object. What i want to do is take that color property and bind it to slice style (fill) but how? Try to bind Color property to Setters Value but it raised a exception that can't bind to read-only value. I've found something like But it shows basic implementation. Is there any detailed example or anyone show an example?

    I have the same requirements for my app, looked at the link you provided and found a solution:

    Create a custom StyleSelector for you chart. Inside the SelectStyle override method access the DataObject that you provide via a Binding to the ItemsSource of your PieSeries like this:
    var color = ((SimpleTimesheet.Portable.ViewModel.ChartItem) (((Telerik.Charting.DataPoint) (item)).DataItem)).Color;
    and just return a new Style with the color from your Databound Object:
    var style = new Style(typeof(Path));
        new Setter(
            new SolidColorBrush(color.ToMediaColor())
    return style;

    Hope this helps. Let me know if you need an example.
