Assembly: DevExpress.Printing.v24.2.Core.dll

Declaration

C#

public static IEnumerable<VisualBrick> GetBricksByTag(
    Page page,
    object tag
)

VB.NET

Public Shared Function GetBricksByTag(
    page As Page,
    tag As Object
) As IEnumerable(Of VisualBrick)

Parameters

Name	Type	Description
page	Page	The page from which to return bricks.
tag	Object	The tag value. A brick is returned if its tag value matches the specified value.

Returns

Type	Description
IEnumerable<VisualBrick>	Bricks from the specified page.

Remarks

BrickSelector methods can be used to post-process a generated document. The basic idea is to first use the Tag property to tag controls on the report page, and then use the GetBricksByTag method to find bricks generated by tagged controls on the report page and adjust their size and position.

Example - Hide the Last Line on a Page

The following code snippet hides the horizontal line that appears at the bottom of each page. The report contains the XRLine control in the DetailBand, with the Tag property set to “line”. This control will be rendered on more than one brick in the document. The last such brick on a page is hidden.

C#

using DevExpress.XtraPrinting;
using DevExpress.XtraReports.UI;
using System.Collections.Generic;
// ...
var report = new XtrReport1();
report.CreateDocument();
foreach (Page currentPage in report.PrintingSystem.Document.Pages) {
    List<Brick> bricks = BrickSelector.GetBricksByTag(currentPage, "line").ToList<Brick>();
    bricks[bricks.Count - 1].IsVisible = false;
}
ReportPrintTool reportTool = new ReportPrintTool(report)
reportTool.ShowRibbonPreviewDialog();  

VB.NET

Imports DevExpress.XtraPrinting
Imports DevExpress.XtraReports.UI
Imports System.Collections.Generic
' ...
Private report = New XtrReport1()
report.CreateDocument()
For Each currentPage As Page In report.PrintingSystem.Document.Pages
    Dim bricks As List(Of Brick) = BrickSelector.GetBricksByTag(currentPage, "line").ToList()
    bricks(bricks.Count - 1).IsVisible = False
