Mark,
I assume that this is a windows form datagrid as you wrote.
Assume that you do this somewhere.
dataGrid.DataSource = dataTable;
dataTable = new DataTable();
Then your dataGrid will show forever the old datatable, which will not be
disposed whatever you do until you do again.
dataGrid.Datasource = dataTable;
