How can I get a DataTable from a GridView?

[rusmo1]

I have a GridView on a webpage and I need to get a DataTable containing
all of its data. The GridView was created via an ObjectDataSource, and
I don't see any members functions of either class (GridView and
ObjectDataSource) that will return me a DataTable.

Sample code and or links would be appreciated!

Thanks in advance,
Will.
