How to configure data binding against the XamDoughtnut control at runtime via C# code and not XAML

Tavi Truman posted over 6 years ago

We have a Semantic Dev application that acquires data via RDF data sources at runtime; the app is data-driven so the declarative approach to XAML-centric programming is not ideal. Instead what I really need to do is bind the data at runtime and assign values to the Itemsoure (Datacontext), RingSeries and other attributes. I have played around with the API but have missed on several attempts. I just need to know what the coded-workflow is to bind to the control at runtime using the XamDoughtnut control API set.

Thanks!

Hello Tavi,

I attached a sample below that demonstrates how to bind the XamDoughnutChart in code behind. Let me know if you have any questions.

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            var source = new HierarchalDataCollection();

            InitializeComponent();
			
            this.xamDoughnutChart.Series.Add(new RingSeries
            {
                LabelMemberPath = "Label",
                ValueMemberPath = "productionShare",
                LabelsPosition = LabelsPosition.BestFit,
                ItemsSource = source
            });
        }
    }

    public class Category
    {
        public string Label { get; set; }
        public double productionShare { get; set; }
    }

    public class HierarchalDataCollection : List<Category>
    {
        public HierarchalDataCollection()
        {
            this.Add(new Category { Label = "Footwear", productionShare = 46 });
            this.Add(new Category { Label = "Clothing", productionShare = 38 });
            this.Add(new Category { Label = "Accessories", productionShare = 16 });
        }
