SubreportBase.ReportSource Property

Gets or sets an XtraReport class instance. This instance’s content is included in the main report.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v24.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

[SRCategory(ReportStringId.CatData)]
public XtraReport ReportSource { get; set; }

VB.NET

<SRCategory(ReportStringId.CatData)>
Public Property ReportSource As XtraReport

Property Value

Type	Description
XtraReport	An XtraReport class instance.

Remarks

Rebuild the solution at design time after you declare an XtraReport class to be able to reference this class in the XRSubreport‘s ReportSource property.

The ReportSource property can only access XtraReport instances, it cannot accept REPX files. In the Report Designer, the ReportSource property drop-down list displays a list of report classes defined in your application (rebuild the app so that all classes are available).

Note

The ReportSource property is not available in Web Report Designer.

Use the ReportSourceUrl property instead of ReportSource to reference a report that is stored in a report definition (REPX) or XML file.

The ReportSourceUrl property value takes precedence over the ReportSource value. If you specify both properties, the XRSubreport includes the content from the report specified by ReportSourceUrl.

See XRSubreport for more information.

Examples

The code sample below adds an XRSubreport item to the report and uses the ReportSource property to reference a detail report.

Tip

Online Example: Use Subreports to Add a Chart

C#

using System.IO;
using System.Drawing;
using DevExpress.XtraReports.UI;
// ...
XRSubreport subreport = new XRSubreport() {
    BoundsF = new RectangleF(0, 100, 550, 25),
};
// "mainReport" is an XtraReport instance.
// Add subreport to the main report's DetailBand.
mainReport.Bands["DetailBand"].Controls.Add(subreport);
// Reference an XtraReport instance named "detailReport" to include its content into the main report.
subreport.ReportSource = detailReport;

VB.NET

Imports System.IO
Imports System.Drawing
Imports DevExpress.XtraReports.UI
' ...
Dim subreport As New XRSubreport() With {.BoundsF = New RectangleF(0, 100, 550, 25)}
' "mainReport" is an XtraReport instance.
' Add subreport to the main report's DetailBand.
mainReport.Bands("DetailBand").Controls.Add(subreport)
' Reference an XtraReport instance named "detailReport" to include its content into the main report.
subreport.ReportSource = detailReport

The following code snippet handles the XRSubreport.BeforePrint event to add an XRLabel control to the referenced report’s instance.

C#

using DevExpress.XtraReports.UI;
// ...
private void Subreport_BeforePrint(object sender, System.ComponentModel.CancelEventArgs e) {
    XRSubreport subreport = (XRSubreport)sender;
    XtraReport report = subreport.ReportSource;
    report.Bands["DetailBand"].Controls.Add(new XRLabel() {
        Text = " - ",
        BoundsF = new RectangleF(450, 0, 100, 25),
        Font = new Font(new FontFamily("Arial"), 9)
    });
}

VB.NET

Imports DevExpress.XtraReports.UI
' ...
Private Sub Subreport_BeforePrint(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs)
    Dim subreport As XRSubreport = DirectCast(sender, XRSubreport)
    Dim report As XtraReport = subreport.ReportSource
    report.Bands("DetailBand").Controls.Add(New XRLabel() With {.Text = " - ", .BoundsF = New RectangleF(450, 0, 100, 25), .Font = New Font(New FontFamily("Arial"), 9)})
End Sub
