We have a grid that has nested grids and the nested grid contains a treeview column.  

When the nested grid is first expanded, its "height" is that of the nodes that are visible due to their expanded state at that time.

But if I expand the treeview nodes, the total height of the nested grid stays the same (it scrolls), whereas I would like it to autoexpand to fit the new height.

Is there a property to set, or do I need to hook up to an event?
