public IDbConnection Connection { get; set; }

Property Value

Type Description

A IDbConnection object representing an open connection to a data source.


To set the appropriate connection, we recommend that you use the Application Designer‘s Connection section. Via this section, you can both set the required connection and specify the corresponding connection string. If you need to specify the Connection property in code, do it between the XafApplication object’s creation and setup:

static void Main() {
   MySolutionWindowsFormsApplication application = new MySolutionWindowsFormsApplication();
   application.Connection = new OracleConnection(...);

By default, SQL connection is used.

The following code snippets (auto-collected from DevExpress Examples) contain references to the Connection property.


The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
