  Sample for PDF button:

  unit Unit1;
  
  interface
  
  uses
    Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
    Dialogs, frxClass, frxExportPDF, frxPreview, frxDsgnIntf, Menus;
  
  type
    TForm1 = class(TForm)
      frxReport1: TfrxReport;
      frxPDFExport1: TfrxPDFExport;
      SaveDialog1: TSaveDialog;
      procedure FormCreate(Sender: TObject);
      procedure frxReport1Preview(Sender: TObject);
      procedure PDFExport(Sender: TObject);
    private
      { Private declarations }
    public
      { Public declarations }
    end;
  
  var
    Form1: TForm1;
  
  implementation
  
  
  {$R *.dfm}
  
  procedure TForm1.PDFExport(Sender: TObject);
  begin
       if SaveDialog1.Execute then
         begin
           frxPDFExport1.FileName:=SaveDialog1.FileName;
           TfrxPreview(frxReport1.Preview).Export(frxPDFExport1);
         end;
  end;
  
  procedure TForm1.FormCreate(Sender: TObject);
  begin
       frxReport1.ShowReport;
  end;
  
  procedure TForm1.frxReport1Preview(Sender: TObject);
  var i, j, mi: integer;
  begin
         TfrxPreviewForm(frxReport1.PreviewForm).PdfB.OnClick:=PDFExport;
         for i := 0 to frxExportFilters.Count - 1 do
           begin
             if TfrxCustomExportFilter(frxExportFilters[i].Filter).ClassName = 'TfrxPDFExport' then
               mi:=i;
           end;
         TfrxPreviewForm(frxReport1.PreviewForm).ExportPopup.Items[mi + 2].OnClick:=PDFExport;
         for i:=0 to TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items.Count-1 do
           begin
             if TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i].Caption=TfrxPreviewForm(frxReport1.PreviewForm).SaveB.Hint then
               begin
                 for j:=0 to TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i].Count-1 do
                   if TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i][j].Caption=TfrxPreviewForm(frxReport1.PreviewForm).ExportPopup.Items[mi + 2].Caption then
                      TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i][j].OnClick:=PDFExport;
               end;
             if TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i].Caption=TfrxPreviewForm(frxReport1.PreviewForm).PdfB.Hint then
               TfrxPreviewForm(frxReport1.PreviewForm).RightMenu.Items[i].OnClick:=PDFExport;
           end;
  end;
  
  end.

  Thanks for the reply.
  
  So there is no way to trap the buttons unless we write our own preview. Correct?

  Sorry, brain fart on my part. Go it!
  
  TfrxPreviewForm(frxReport.PreviewForm).EmailB.OnClick:=MyEMailAction;
  
  Thank you for your help!
