Remarks

XPObjectSource can be used at design time via the Report Wizard:

You can also initialize and enable XPObjectSource in code. Create an XPObjectSource instance. Initialize the XPObjectSource.ConnectionStringName property and pass the persistent object type to the XPObjectSource.SetEntityType method. Then, pass the XPObjectSource instance to the XtraReportBase.DataSource property of your XtraReport.

C#

using DevExpress.Xpo;
using DevExpress.Xpo.Metadata;
using DevExpress.XtraReports;
// ... 
XPObjectSource dataSource = new XPObjectSource();
dataSource.ConnectionStringName = "ConnectionString";
dataSource.SetEntityType(typeof(Product));
using(XtraReport2 report = new XtraReport2()) {
    report.DataSource = dataSource;
    // ... 
    // Preview the report or do something else. 
    // .. 
}

VB.NET

Imports DevExpress.Xpo
Imports DevExpress.Xpo.Metadata
Imports DevExpress.XtraReports
' ... 
Private dataSource As New XPObjectSource()
dataSource.ConnectionStringName = "ConnectionString"
dataSource.SetEntityType(GetType(Product))
Using report As New XtraReport2()
    report.DataSource = dataSource
    ' ... 
    ' Preview the report or do something else. 
    ' .. 
End Using
