FeatureDataGrid Selection Changed Event

I am trying to get attributes off of the last selected row but when I try to get that graphic in the selection changed event the graphics collection has not been updated yet. How can I trigger an event when the SelectedGraphics collection changes.

You can use FeatureDataGrid.SelectionChanged event and iterate through e.AddedItems. To convert row to graphic, you can use the following method (add using System.Reflection).

private void MyDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
 foreach (var item in e.AddedItems)
 {
  var g = GetGraphicSibling(item);
 }
}

private static Graphic GetGraphicSibling(object item)
{
 if (item != null)
 {
  MethodInfo mi = item.GetType().GetMethod("GetGraphicSibling");
  if (mi != null)
   return mi.Invoke(item, null) as Graphic;
 }
 return null;
}
