DataConnectionParametersBase Class

Serves as the base for classes that contain the parameters of data connections.

Namespace:DevExpress.DataAccess.ConnectionParameters
Assembly:DevExpress.DataAccess.v17.2.dll

Expanded Syntax

Expanded Remarks

The DataConnectionParametersBase descendants contain settings used to specify connection parameters for the SqlDataSource. Different DataConnectionParametersBase descendants provide connection parameters for different DBMS and data file formats. For instance, you can use the MsSqlConnectionParameters, OracleConnectionParameters, XmlFileConnectionParameters and many others.

To specify connection parameters for the specified SqlDataSource, create the required DataConnectionParametersBase descendant, specify its settings and assign the resulting DataConnectionParametersBase object to the SqlDataSource.ConnectionParameters property.

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E4759.

This example demonstrates how to customize connection settings before the DashboardViewer connects to a database using the DevExpress.DashboardWin.DashboardViewer.ConfigureDataConnection event.

In this example, the dashboard's XML definition contains a path to the secured Microsoft Access database. To visualize data from this database file, it is necessary to provide connection parameters; in particular, a user name and password for authentication. The DevExpress.DashboardWin.DashboardViewer.ConfigureDataConnection event is used for this purpose. Its Access97ConnectionParameters.UserName and FileConnectionParametersBase.Password parameters are used to provide the user name and password respectively.
