Outline Settings - collapse nodes

rbuser

Hi there,

I have two groups: 'Year' & 'Date of meeting' and have enabled Outline
Settings. These work fine except that the whole tree view is extended when
the report is opened. Is there a way to collapse the nodes so that they
would only show, for example, a list of 'Years' initially but the selected
year would expand to show the dates when selected.

Many thanks

Hi,

For future reference, please use your real name when posting to these
newsgroups.

You can access the TppOutlineViewer object directly from the report in code
using the OutlineViewer property of the PreviewForm. (Example below). The
TppOutlineViewer object descends from the TTreeView class so you can try to
call FullExpand or FullCollapse as needed in the PreviewFormCreate event.

uses
ppPrvDlg;

procedure TForm1.ppReport1PreviewFormCreate(Sender: TObject);
begin

TppPrintPreview(ppReport1.PreviewForm).OutlineViewer.FullCollapse;

end;

Nico,

I tried that and it compiles OK but doesn't make any difference. I am using
RB 11.06 for Delphi 6 Standard. Is it a version issue ?

Thanks

Hello,

Upon further research, the outline is not designed to be manually collapsed
upon load. This is something we will consider enhancing for a later
release.

The main issue is that we do not have an event that fires late enought to
collapse the outline on load. Currently the only option would be to create
a custom previewer that perhaps overrides an event that fires after the
Outline is generated (such as the OnPageChange event). From here you will
need to perform something similar to what happens inside the
TppOutlineViewer.OutlineFullCollapseEvent to get the effect you are after.
