Another option is to go with the more generic and pure delcarative approach which comes in handy in MVVM projects. Here's what I did... I really like it because it is very generic and I can reuse the same behavior on as many grids that use different collections.

1. Implemented the XamGrid
2. Created a generic behavior that I attach to the grid... this behavior attaches to the grid's SelectedRowsCollectionChanged event. When an item is selected, it sends a message capability of the MVVM Light Toolkit.
3. In my view model, I register a listener for the specific type of data... like so.

Behavior:
public class IgGridControlRowSelectedBehavior : Behavior<XamGrid> {
  protected override void OnAttached() {
    base.OnAttached();
    if (AssociatedObject != null)
      AssociatedObject.SelectedRowsCollectionChanged += SelectedRowsCollectionChanged;
  }

  protected override void OnDetaching() {
    if (AssociatedObject != null)
      AssociatedObject.SelectedRowsCollectionChanged -= SelectedRowsCollectionChanged;
    base.OnDetaching();
  }
  void SelectedRowsCollectionChanged(object sender, SelectionCollectionChangedEventArgs<SelectedRowsCollection> e) {
    if (e.NewSelectedItems.Count == 1) {

      // get reference to the selected row in the grid.
      var rowData = e.NewSelectedItems[0].Data;

      // let anyone listening for a new selected item know it was selected
      if (rowData != null)
        Messenger.Default.Send(rowData, rowData.GetType());
    }
  }
}

Grid:
<ig:XamGrid x:Name="CourseGrid"
            ItemsSource="{Binding Path=CourseCollectionViewSource.View}"
            AutoGenerateColumns="False">
  <ig:XamGrid.SelectionSettings>
    <ig:SelectionSettings CellClickAction="SelectRow" />
  </ig:XamGrid.SelectionSettings>
  <ig:XamGrid.Columns>[...]</ig:XamGrid.Columns>
  <i:Interaction.Behaviors>
    <myBehaviors:IgGridControlRowSelectedBehavior />
  </i:Interaction.Behaviors>
</ig:XamGrid>

Where the namespace "i" = xmlns:i=http://schemas.microsoft.com/expression/2010/interactivity

View Model listening for selected items:
Messenger.Default.Register<object>(this, typeof(Course), message => SelectedCourse = message as Course);

 

Hi, 

Those are all the settings you need. 

Can you attach a sample of this behavior not working?

I have the exact same values for the SelectionSettings. But, my XamGrid still doesn't seem to select the row. It's still recognizing cell selection. Are there any other properties in XamGrid that could override these attributes?

Hi, 

To answer your other question you can set the RowHover property on the grid to Cell, Row, or None, to stop the hovering effects.
