Hi,

I'm using an object data provider for a BindingList collection of objects with a nested BindingList object i.e. 2 level hierarchy.

I've specified HighlightAtlernateRecords = True on the FieldLayoutSettings of the FielLayout for the Parent level of the hierarchy only.

When rendered with the Child level collapsed, the records/rows alternate background colors as one would expect.

When the Parent rows are expanded to show the nested child level, the Parent's background color rendering appears to be controled by the number of records in the preceeding row's Child section (ExpandableFieldRecordPresenter?).  In my example, when the first record is expanded, the second record flips background color, now matching the one above it.

This seems wrong to me.  My understanding, based on the "xamDataGrid Composition Diagram" is that the subordinate records are contained within the  ExpandableFieldRecordPresenter which, in turn, is contained withn the Parent record's DataRecordPresenter.

Attached is a sample project that demonstartes this.  Each parent has the same number of subordinate records and just happens to end up with every Parent record rendered with the same background color when all are expanded.  This would vary with odd and even numbers of subordinate records.

Is this a bug or a feature?
