This article and source code demonstrate how to bind objects
stored in a generic List (Of T) to a DataGridView and how to retrieve an
individual object when a row header of the DataGridView is double-clicked. The
DataGridView Row's DataBoundItem property is used to retrieve the object that is
bound to row.
The DataGridView, new in Visual Basic 2005, provides many new
members for displaying and manipulating data. One member, the DataGridView Row's
DataBoundItem, makes it each to 'get at' the data behind a DataGridView row.
This member is especially useful when working with a data source such as a
generic List (Of T) object.
