Open new XAML page using DataPointSelection

I would like to use DataPointSelection to open a new XAML page using NavigationPage. After adding a new class such as the following:

public class CustomSelectionBehavior : ChartSelectionBehavior
        protected override async void OnSelectionChanged(ChartSelectionEventArgs arg)
            await Navigation.PushAsync(new SomePage());

I receive a "The name 'Navigation' does not exist in the current context" error.

What is the proper way to handle this?

Secondly, I need to open a different page based on what data point is selected, such as:

if (DataPointId == DataPoint1Id)
  // open data point 1 page
else if (DataPointId == DataPoint2Id
  // open data point 2 page

What is the proper way to handle this as well?

I realized that I can add the PropertyChanged="ClickHandler" property to the Chart... The issue now is that this is fired the-number-of-data-points times immediately when the page loads. How to I prevent this from firing until a data point is actually selected? Using XAML

Hi Drew Wilson, 
Thanks for using Syncfusion products. 
We are able to achieve your requirement using chart’s SelectionChanged event. We have prepared a sample for this and it can be downloaded in below link. 
Please let us know for any concerns.
