How to bind underlying model property to Chart's behavior property?

This article describes the process of binding of binding a ViewModel property to a behavior property in a WPF Chart.

By default, WPF Chart behaviors are derived from DependencyObject. Meaning the DataContext is not automatically set for these behavior classes. However, you can bind a ViewModel property to a Chart behavior property by specifying the ViewModel as the source.

The following code samples demonstrate how to bind the view model property to the Chart behavior property.

XAML:

<Grid>
    <Grid.Resources>
        <local:ViewModel x:Key="viewModel"/>
    </Grid.Resources>
    <chart:SfChart>
        <chart:SfChart.Behaviors>
            <chart:ChartZoomPanBehavior EnableZoomingToolBar="{Binding EnableZoomingToolBar,Source={StaticResource viewModel} }"   />
        </chart:SfChart.Behaviors>
    </chart:SfChart>
 </Grid>

C#:

public class ViewModel : INotifyPropertyChanged
{
    private bool enableZoomingToolBar = true;
    public bool EnableZoomingToolBar
    {
       get
       {
        return enableZoomingToolBar;
       }
       set
       {
        enableZoomingToolBar = value;
        OnPropertyChanged("EnableZoomingToolBar");
       }
    }
 
    public event PropertyChangedEventHandler PropertyChanged;
 
    private void OnPropertyChanged(string propertyName)
    {
      if (PropertyChanged != null)
      {
        PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
      }
    }
}
