The DesignerDataParameter class is one of several types that represent the schema of a data store at design-time. These schema items are made available to controls by designers implementing the IDataEnvironment interface. Controls access schema objects by calling the GetConnectionSchema method of the interface.

The DesignerDataParameter class represents the parameters required to call a stored procedure in the data store. The DesignerDataStoredProcedure.Parameters property contains a collection of DesignerDataParameter objects.
