GroupHeaderBand.PrintAcrossBands Property

Gets or sets whether this band is printed as the background layer across all other bands that belong to the same group.

Namespace : DevExpress.XtraReports.UI

Assembly : DevExpress.XtraReports.v25.2.dll

NuGet Package : DevExpress.Reporting.Core

Declaration

C#
VB.NET

csharp

[Browsable(true)]
public override bool PrintAcrossBands { get; set; }

<Browsable(True)>
Public Overrides Property PrintAcrossBands As Boolean

Property Value

Type	Description
Boolean

true if this band is printed as the background layer across all other bands that belong to the same group; otherwise, false.

Remarks

The PrintAcrossBands property enables you to do the following:

Display continuous content side-by-side with bands that belong to the same group –– header, detail, and footer bands.
Create a custom watermark for a group, if the XRWatermark control does not meet your needs.

If the cross-band content does not reach the group’s bottom, the content is not stretched nor repeated.

Display Cross-Band Content and Group Headers

Use one of the following methods:

Add an outer GroupHeaderBand that includes cross-band content, and an inner GroupHeaderBand that includes group headers. Specify group field(s) in the outer band. Enable the outer band’s PrintAcrossBands property.
Add a GroupHeaderBand that includes cross-band content, and add a SubBand to the GroupHeaderBand. Place headers on the SubBand. Enable the GroupHeaderBand ‘s PrintAcrossBands property.

Tips and Limitations

The PrintAcrossBands setting is ignored in the following situations:

When the band’s RepeatEveryPage property is set to true.
When a group contains a VerticalDetailBand instead of a DetailBand.
When the GroupHeaderBand contains the XRSubreport control. Consider side-by-side XRSubreport controls instead.

The PrintAcrossBands property is not available in the VerticalHeaderBand class.

End-User Designer - Set the PrintAcrossBands Property Value

Click the GroupHeaderBand ‘s smart tag and check the Print Across Bands property.

The band’s icon indicates if the band is printed across other group bands:

PrintAcrossBands = false

PrintAcrossBands = true

Tip

See the Create a Report with Cross-Band Content and Populated Empty Space in the VS Report Designer topic for information on how you can use the PrintAcrossBands property to create a band that is printed across the report’s other content.

Runtime Example

The code sample below illustrates how to add content that shows group information (the Order ID) and is printed across the DetailBand and GroupFooterBand. The report is bound to the OrderDetailsExtended view from the sample Northwind database that ships with the XtraReports installation.
