How to get hierarchical data in datagrids when using arraylist as data source?

When a DataSet is used as data source for a DataGrid one can get
hiearachical datagrid by using relations among the DataTables of the
DataSet. (By hierarchical datagrid, I mean columns that can be expanded
and collapsed with '+' buttons).

How can I achieve a hierarchical DataGrid when using an ArrayList as
data source?

I have tried binding ArrayList containing an ArrayList to the datagrid,
but this just shows the public properties of the ArrayList objects in
the DataGrid.

regards

Stig Nielsson

I have a class that inherits from DataGrid. I can set the rowheights in a DataGrid by tappig into the "get_Datagridrows" method. However, this does not work for classes that inherit from DataGrid. Anyone know how to do this on derived classes? I find it apalling that Microsoft provided a DataGrid that is so inflexible! -- Dennis in Houston
