I have a hieracrhical data structure where children records are of different types.  I am binding the ActiveDataItem, but that only works for the parent selection.  When selecting a child, the activedataitem binds null, and nothing captures the child selection.  I want to bind both the parent and the child to properties in my datacontext.

Currently, I am using RecordActivated event to manually set one-way binding.

if (e.Record != null && e.Record.ParentDataRecord != null)

container.ParentProperty = e.Record.ParentDataRecord.DataItem as ParentPropertyType;

else

container.ParentProperty = null;

var dataRecord = e.Record as DataRecord;

if (dataRecord != null)

container.Property = dataRecord.DataItem as PropertyType;

else

container.Property =  null;
