Hello all,

Thanks in advance

There are many different approaches. First, search Google for "DataGrid Master Detail". There are a lot of examples.

My approach to this has always been to re-bind the DataGrid. In other words, I do the work in the data source. I like to use either DataTables that I build dynamically, or a DataReader supplying an ArrayList, which in turn supplies the DataGrid.

I've read something about the .net's databinding support for parent-child records via datagrid+datasets.

As far as I can remember, the KB states that when moving from one record to another on the parent table, there are unused references that's left uncollected by the GC, and what's worse, the garbage get's piled up as you move along the records. I'll check on the KB and post it here. The KB suggested however to use a workaround similar to tgreer's post.
