Create TOC (Complete Report from Code in Delphi)

seoBOXXseoBOXX
edited 1:46AM in FastReport VCL 5
Hi,

i create the report complete from code and not using the designer. I want to have a TOC including the startpage of the report category.

How can i figure out wich page has what page number in the final pass or is there a way to get the pagenumber from the page?

I am able to get the page using FindObject but that did not help me.

Any suggestions and/or examples? This is my first project using fastreport so i am somehow new to that.

Best regards and many thanks in advance,

Andy

    Hi,

    thanks for the quick response ... i tried that but it does not seem to work ...

    i create a coverpage, intropage, the indexpage and the datapages in that sequence

    in the memo (called datafield) of the toc i create them with the following code:
       // left space
   CurrentWidth := 25;
   // TOC Entry
   DataField := TfrxMemoView.Create(DataBand);
   DataField.CreateUniqueName;
   DataField.AllowHTMLTags := true;
   DataField.AllowExpressions := true;
   DataField.HAlign := frxClass.haLeft;
   DataField.VAlign := frxClass.vaTop;
   DataField.Font.Size := 8;
   DataField.Font.Style := DataField.Font.Style + [fsbold];
   DataField.WordWrap := false;
   DataField.WordBreak := false;
   DataField.Text := GetStringFromID(TDetailViewDataObject(TempNode.DataObject).ID,1) + '  ......................................................................................................................' +
                                                                                        '......................................................................................................................';
   DataField.SetBounds(CurrentWidth,CurrentHeight,(IndexPage.Width - IndexPage.LeftMargin - IndexPage.RightMargin - RightMarginCorrector) - 80 - CurrentWidth,20);
   DataField.Hyperlink.Kind := hkAnchor;
   DataField.Hyperlink.Value := '[<TOCANCHOR' + TDetailViewDataObject(TempNode.DataObject).ID.ToString + '>]';
   CurrentWidth := (IndexPage.Width - IndexPage.LeftMargin - IndexPage.RightMargin - RightMarginCorrector) - 80 - CurrentWidth;
   // TOC Page number
   DataField := TfrxMemoView.Create(DataBand);
   DataField.CreateUniqueName;
   DataField.AllowHTMLTags := true;
   DataField.AllowExpressions := true;
   DataField.HAlign := frxClass.haRight;
   DataField.VAlign := frxClass.vaTop;
   DataField.Font.Size := 8;
   DataField.Font.Style := DataField.Font.Style + [fsbold];
   DataField.WordWrap := false;
   DataField.WordBreak := false;
   DataField.Text := '[Engine.GetAnchorPage(<TOCANCHOR' + TDetailViewDataObject(TempNode.DataObject).ID.ToString + '>)]';
   DataField.SetBounds(CurrentWidth,CurrentHeight,(IndexPage.Width - IndexPage.LeftMargin - IndexPage.RightMargin - RightMarginCorrector) - CurrentWidth - 40,20);
   // adjust height
   CurrentHeight := CurrentHeight + 20;

    for each first databand of the datapages i add the following code
       // add masterdata band
   DataBand := TfrxMasterData.Create(Page);
   DataBand.CreateUniqueName;
   DataBand.DataSet := AnalysisDataModule.URLReportEmptyUserDataSet;
   DataBand.FHeader := TableHeader;
   DataBand.Stretched := true;
   DataBand.Top := TableHeader.Top + TableHeader.Height + 1;
   DataBand.Height := 230;

   // TOC anchor stuff
   URLReport.ScriptText.Add('procedure ' + DataBand.Name +  'OnBeforePrint(Sender: TfrxComponent);');
   URLReport.ScriptText.Add('begin');
   URLReport.ScriptText.Add(' Engine.AddAnchor(<TOCANCHOR' + TDetailViewDataObject(TempNode.DataObject).ID.ToString + '>);');
   URLReport.ScriptText.Add('end;');

   // Global Script Stuff
   AnchorScript.Add(DataBand.Name +  '.OnbeforePrint :=' + '''' + DataBand.Name + 'OnBeforePrint' + '''' + ';');

    Then i get this error message ...

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
