Creates an Object Space.

Namespace: DevExpress.Persistent.Base.ReportsV2

Assembly: DevExpress.Persistent.Base.v22.1.dll

Declaration

public static IObjectSpace CreateObjectSpace(
    Type dataType,
    IServiceProvider serviceProvider
)

Parameters

Name Type Description
dataType Type

A Type object that specifies the business object type for which the Object Space is retrieved.

serviceProvider IServiceProvider

An IServiceProvider object.

Returns

Type Description
IObjectSpace

An IObjectSpace object.

Remarks

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);
}
