Printing one page of Labels

1. offizieller Beitrag

    I have created a label editor and can print all the labels from the preview component, does anyone know how to print just the first page of labels?

    also I would like to make my own preview using a form designer can anyone help with this?

    thanks

    Instead of PreviewReport.Print(Caption);

    use PrintPages(First, Last: Integer; const title: string);

    (unit WPFPrv)

    If you save the label sheet this is a file WPR format - a file which contains multiple pages. You need the WPFReportEngine to view and print this file. Please use the original preview component as a template for a viewer. (unit WPFPrv)

    I have tried this method looking at the print preview unit and I'm using

    the following 2 procedrues

    The problem is that I am using fields and when the page is displayed in the 2nd form designer I only get a preview of the first label or which ever record is being viewed?

    How do I view all the labels?

    I have the same problem with the ReportArea. Only first record is displayed in preview.
    Table Alias and ObjName of the report area are the same. MasterDataSource is set.

    There is extra code missing in the even OnReportState.

    WPForm1.WPFReportEngine1ReportState(Sender: TObject;
    Area: TWPFReportArea; State: TWPFReportState; Number: Integer;
    var DoBegin: Boolean);
    begin
    if state = wpfBeginReport then
    begin
    PageNr := 0;
    LinNr := 0;
    Summe := 0;
    end
    else
    if State=wpfNeedNewRow then
    begin
    // For report Areas!!!
    DoBegin := not DetailDataset.EOF;
    end
    else if State=wpfNeedNewDocument then
    begin

    end;
    end;
