As a C# example, here is a typical object code in which we add one root row and a child row for it in the TreeGridView developed by Mike Rideout: TreeGridNode node = (null, 'Using DataView filter when binding to DataGridView', 'tab', 1:02 AM') The object constructs used to provide you with a friendly way to manipulate hierarchical rows in DataGridView may also add new performance issues. We all know that this control becomes noticeably slow if we add a significant amount of records to it, and you can even find comments about that in Mark's blog. A big class of problems for such solutions is the DataGridView control itself.
