To access data in an XAF application, you do not need to use an ORM-specific context or query data from the database directly. Instead of these techniques, use an Object Space’s methods (see Data Manipulation and Business Logic).

The CreateObjectSpace static method allows you to access an Object Space in report scripts:

private void report_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {
    DevExpress.ExpressApp.IObjectSpace objectSpace = 
        DevExpress.Persistent.Base.ReportsV2.DataSourceBase.CreateObjectSpace(typeof(MyObject), (DevExpress.XtraReports.UI.XtraReport)sender);
