I have a xamDataGrid with two levels of data. (see other question on SO).
There is very little visually that shows where one level of data starts and a seconds begins. Take a look at this snippet from the xamFeatureBrowser:
What I want, is to indent the second level a little. RecordPresenter has a NestedContentMargin property, but it's read-only...
An alternative, would be to display some kind of thin footer for each second level grid.
