DataProviderBase Class

Serves as the base class for classes that represent a data provider.

Namespace:DevExpress.DataAccess
Assembly:DevExpress.DataAccess.v19.1.dll
NOTE: This type is now obsolete.
The DataProviderBase class is obsolete now. Use the DashboardSqlDataSource class instead

Expanded Syntax

Expanded Remarks

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

  • Pass the created DevExpress.DataAccess.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.
