When using a hierarchy of column headers (e.g. Days-Resources), is it possible to style the different levels of header differently? I actually want to hide parent header completely and I thought I might be able to do this with styling, but there doesn't seem to be any property in the BeforeHeaderRenderEventArgs which allows you to determine which header level is being rendered.
Even if my idea of using styling to hide a column header is silly (for now I'll just set the column name to a blank string, though the empty column header will still appear), it'd be good if it was possible to style the multiple header levels differently.
