I created a SF Maintenance form in VB. Added a BO and a List View and set up a SQL statement to receive data from a table. The list view populates but the maintenance tool bar does not become available. In other words all the buttons are not available. What should I do. I am brand new to SF so I am not sure how to approach finding a solution. TIA.

Yep, the ListView is generally on for displaying data while the Grid is used for editing data. 

In order to use a ChildBO on the form, you're most likely going to want to place the child BO on the form and fill it with all fo the records that belong to the parent business object (child.FillByParent() should help with that...).  Then, on the parent business object, set the ChildAutoFilterOption property to MatchCurrentRow... this will change the filter on the child business object to only show the records that match the selected record in the parent.  Then, just make sure that the parent business object is navigated to the correct row (the CurrencyManager within the BusinessBindingSource should take care of that, but some grids don't use the CurrencyManager the same way the basic .NET grid does) and the child business object will be filtered to show the child records.
