[Solved] Binding not working for "Stroke"?

[Erez]

Hi,

I'm creating a dynamic chart using the SeriesProvider and required that each series will be displayed with different color.
Therefore, I created a CategoricalSeriesDescriptor for a LineSeries and tried to bind the Stroke property to a Brush value coming from the model.

After many failed test I found that even if I set the binding to some bogus name, the BindingFailed event is not being called, thus Binding does not even occur. Setting the value to a "real" color (not bound) works.

Could please assist?

                    <telerikChart:ChartSeriesProvider Source="{Binding Trends}" x:Name="provider" >
                        <telerikChart:ChartSeriesProvider.SeriesDescriptors >
                            <telerikChart:CategoricalSeriesDescriptor ItemsSourcePath="Items" ValuePath="Value" CategoryPath="DateTime">
                                <telerikChart:CategoricalSeriesDescriptor.Style>
                                    <Style TargetType="telerikChart:LineSeries">
                                        <Setter Property="Stroke" Value="{Binding SeriesStroke}"/>
                                    </Style>
                                </telerikChart:CategoricalSeriesDescriptor.Style>
                            </telerikChart:CategoricalSeriesDescriptor>
                        </telerikChart:ChartSeriesProvider.SeriesDescriptors>
                    </telerikChart:ChartSeriesProvider>
                </telerikChart:RadCartesianChart.SeriesProvider>

Thank you,

Update: I solve it by creating a custom descriptor class, but it's far from elegant. 
I would prefer to use binding, if possible.

Hello,

Unfortunately binding in setter is not supported in WinRT.

Let me know should you have any other questions.
