Custom nested editor for non-collection property
posted

Each of my records has a complex property "Child" which is a single object (not IEnumerable).

I want rows to be expandable with custom editor showing contents of "Child" property when expanded.

I have assigned ExpandableFieldRecordPresenterStyle and set IsExpandable=True on "Child" field.

According to documentation:

"If the associated Field's DataType implements the IEnumerable interface (...) Otherwise, the NestedContent will contain an ExpandedCellPresenter with the actual cell value."

Unfortunately even though expansion indicator is displayed, it does not work. When I click on it nothing is expanded and the expander just disappears completely.
