The Binding object has several new members in the .NET Framework 2.0 that enable greater control over the binding operation. For example, you can control how data is formatted in a bound control, when the data source is updated, and how null and DBNull values in the data source are handled. These new members are also supported with corresponding Add methods in the ControlBindingsCollection. You can take advantage of these additions by using the Formatting and Advanced Binding dialog box in Visual Studio or through code. In addition, the Binding object has better support for handling exceptions and errors that can occur in the binding process with the addition of the BindingComplete event.
