How to Display Print Preview and Print the Tree List

• Jul 30, 2021

The following code snippet demonstrates how to create a report link for the TreeList control and display the print preview window, by using a TdxComponentPrinter component. This component is shipped with the ExpressPrinting System, which is a separate product.

Delphi

uses
//...
  ..., dxPScxTL5Lnk;
//...
var
  ATreeListReportLink: TBasedxReportLink;
begin
  // Creates a report link for the TreeList control and adds it to a component printer
  ATreeListReportLink := dxComponentPrinter1.AddLink(TreeListControl);
  // Invokes the print preview window
  dxComponentPrinter1.Preview(True, ATreeListReportLink);
end;

C++

//...
#pragma link "dxPScxTL5Lnk"
//...
  // Creates a report link for the TreeList control and adds it to a component printer
  TBasedxReportLink *ATreeListReportLink = dxComponentPrinter1->AddLink(TreeLinkControl);
  // Invokes the print preview window
  dxComponentPrinter1->Preview(True, ATreeListReportLink);

The result is shown in the image below.
