The IDataSourceFieldSchema interface allows a class to implement a set of properties that describe a field in a data source. The DataSetFieldSchema class implements the IDataSourceFieldSchema interface.

Classes that implement the IDataSourceFieldSchema are used by custom control designer components to provide lists of data source fields and properties for data-bound controls at design time.
