Question

I have the following model:

public class Model : INotifyPropertyChanged  {   public ObservableCollection<ViewElement> Elements { get; set; }    public ViewElement CurrentElement { get; set; } } 

And the following grid where the parent DataContext is the above model:

<dg:XamDataGrid DataSource='{Binding Path=Elements}' /> 

I want to bind the CurrentElement property to the Selected Item of the Grid, similar to how I would in a ListView:

    <ListView x:Name='playbackSteps'           ItemsSource='{Binding Path=Elements}'           SelectedItem='{Binding Path=CurrentElement}' /> 

How would you suggest I do this?

As stated on the Infragistics forum, the XamDataGrid exposes an IsSynchronizedWithCurrentItem property. To take advantage of this, you need a ListCollectionView of your ObservableCollection. Something like this:

public ListCollectionView ElementsView {get;set;}  // In the constructor: this.ElementsView = new ListCollectionView(Elements); 

Then bind your XamDataGrid to ElementsView.
