Remarks

To supply a data source with data using a data provider, do one of the following:

• Pass the created DataConnection class instance to the DataProviderBase descendant constructor. Optionally, you can specify the SQL query to select the required data.
• Pass the created DataConnectionParametersBase descendant instance to the DataProviderBase descendant constructor and specify the connection name. Also, you need to specify the SQL query to select the required data.
