    Hierarchical Data
</h1>
<p>
    Regular grids and <b>CollectionView</b> objects are
    great for dealing with flat data but not with data
    structures having hierarchical structure. However,
    FlexGrid provides a few properties and extensions
    to help you deal with such data structures as well.

    The next topics show different ways to handle hierarchical
    data with FlexGrid, including Master-Detail, Tree Grids,
    and Row Details.
