Datagridview / Treeview Question

A search for "hierarchical datagridview" found this (http://www.awprofessional.com/articles/article.asp?p=446453&seqNum=2&rl=1):

The DataGrid could be bound to a collection of collections, such as a DataSet, and if so, the DataGrid presented hierarchical navigation controls to move through the collections of data. However, this capability was rarely used, partly because the navigation controls that were presented inside the DataGrid were a little unintuitive and could leave the user disoriented. As a result, the Windows Client team that developed the DataGridView control decided not to support hierarchical navigation within the control. The DataGridView is designed to present a single collection of data at a time. You can still achieve an intuitive hierarchical navigation through data, but you will usually use more than one control to do so, adopting a master-details approach as discussed in previous chapters.

datagrid view is different from datagrid in the 2003 version of vb.net. in that aspect that you dont have such and "click and show child table" functionallity
