How to read selectedPoint.DataItem in RadCartesianChartView

[HV]

Hi,

I'm trying to read the value of selectedPoint.DataItem in RadCartesianChartView when selecting the bar. 

DataPoint selectedPoint = e.P0.SelectedDataPoint();
var dataItem = selectedPoint.DataItem;

Casting the dataItem to C# object like

public class CastJavaObject
    {
        public static T Cast<T>(Java.Lang.Object? obj) where T : class
        {
            var propInfo = obj.GetType().GetProperty("Instance");
            return propInfo == null ? null : propInfo.GetValue(obj, null) as T;
        }
    }

and using the CastJavaObject like

var poco = CastJavaObject.Cast<Result>(dataItem);

The problem is Casting the dataItem always null. Any help on reading the dataItem values.

Thanks.

Hi, 

You have the information for the selected point in this way:

ChartSelectionBehavior selectionBehavior = new ChartSelectionBehavior();
            selectionBehavior.SeriesSelectionMode = ChartSelectionMode.None;
			selectionBehavior.DataPointsSelectionMode = ChartSelectionMode.Single;	
            chart.Behaviors.Add(selectionBehavior);
            selectionBehavior.SelectionChange += SelectionBehavior_SelectionChange;

        private void SelectionBehavior_SelectionChange(object sender, ChartSelectionChangeEventArgs e)
        {
            DataPoint selectedPoint = e.P0.SelectedDataPoint();
        }

How to display the data is up to you. This requires custom development from your side.
