PreviewReportCustomizationService Class
Enables you to customize the current report and assign a CachedReportSourceWeb object when the Report Designer is about to be switched to the Preview tab.
Namespace: DevExpress.XtraReports.Web.ReportDesigner.Services
Assembly: DevExpress.XtraReports.v18.2.Web.dll
Declaration
Remarks
You can create a descendant from the PreviewReportCustomizationService and override the following methods:
- CustomizeReport - allows you to change the report’s settings when it is about to be previewed. These changes are in effect only in the Preview tab.
- CreateCachedReportSource - is called after the CustomizeReport method and allows you to assign a CachedReportSourceWeb object to the customized report.
The following example demonstrates how to use this service to change the report’s orientation and assign a new CachedReportSourceWeb instance.
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.Web;
using DevExpress.XtraReports.Web.ReportDesigner.Services;
public class MyPreviewReportCustomizationService: PreviewReportCustomizationService {
public override void CustomizeReport(XtraReport report) {
report.Landscape = true;
}
public override CachedReportSourceWeb CreateCachedReportSource(XtraReport report) {
return new CachedReportSourceWeb(report);
}
}
Then, register your custom service implementation at the application’s startup.
