This code samples demonstrates the following:

1. DataBinding a combobox to the same Datasource as a DataGridView and have updated selection in the combobox be reflected immediately in the grid.
2. DataBinding with "OnPropertyChange", rather than "OnValidation" which is a temporary workaround while issue VWG-3933 is being fixed.
3. Sharing the same instance of a dataset between a form and a "standalone" UserControl with it's own private variables for storing it's DataSet member. Changing data in either the Form or the UserControl, updates both because of the databindings and sharing.
4. Sharing the same instance of a dataset between multiple forms and UserControls in same fashion as in 3. Updating data in any one of the "slave forms", updates all the other "slave forms" as well as the masterform and it's UserControl.

To try this out, click either of the "Open" buttons to open one or more "slave forms". then try changing data in any of the forms, or on the master form and see the data change on all instances.
