Update ViewModel when I touch a chart fragment in Doughnut Chart

[Juan (Charly) Garibay]

Hi guys,

I'm using Syncfusion Xamarin SfChart to display a Doughnut Chart in one of my projects. I bind a property of my viewmodel to SelectedDataPointIndex of DoughnutSeries. When I update my model chart is updated with new selection, but, when I select/touch a chart fragment, my model is not updated. :'(

My chart configuration is:

<chart:SfChart BackgroundColor="White" HeightRequest="200">

    <chart:SfChart.Series>

        <chart:DoughnutSeries ItemsSource="{Binding Accounts}"

            XBindingPath="Description"

            YBindingPath="Amount"

            ExplodeOnTouch="False"

            EnableAnimation="True"

            StrokeWidth="2"

            StrokeColor="White"

            DoughnutCoefficient="0.75"

            EnableDataPointSelection="True"

            ListenPropertyChange="True"

            SelectedDataPointColor="#1094F6"

            SelectedDataPointIndex="{Binding Chart_SelectionIndex}">

        </chart:DoughnutSeries>

    </chart:SfChart.Series>

</chart:SfChart>

I'm using Syncfusion.SfChart.XForms version 14.3451.0.49.

Any idea on how to update my view model? What is wrong with this? Does SfChart support two-way binding?

Thanks in advance.
