Hi Alexander,
Thanks for using Syncfusion products.
We request you to use the following code to get the notification when selection is changed in the MVVM pattern.
[C#]
public class CustomSelectionBehavior : ChartSelectionBehavior
{
protected override void OnSelectionChanged(ChartSelectionEventArgs arg)
{
base.OnSelectionChanged(arg);
//create a popupwindow
}
}
|
[XAML]
<chart:SfChart.ChartBehaviors> <local:CustomSelectionBehavior /> </chart:SfChart.ChartBehaviors>
|
Please let us know if you need any further assistance on this.
Thanks,
Yuvaraj P
