Another future feature wish

rbuser

The ability to show/hide report bands at runtime with a tree similar to
the OutLine.
In that way the users could hide the detail bands, group footers, etc
and print just the data they want each time. Again, i know it's a very
complex task because you need to recalculate all the report pages
(dimensions at least). But, it could be great.

Thankyou for the suggestion.

Technically it should be possible. You could code it yourself if you need it
implemented today. In the current implementation, the Outline appears
separately from the page viewer area of the preview form. The report engine
can support regeneration from the preview tab, as DrillDown subreports force
pages to be regenerated. You could add a treeview component in a custom
preview plugin. You can get at the report from the Viewer property inside of
your preview plugin descendent class. Do a typecast as
TppReport(Viewer.Report) and then loop through the bands and components and
recursively loop through the subreport's as well. This way you could build a
tree like structure that showed the bands and subreports only. If you see
our ReportTree, it displays the report components in a tree. See
ppTreeVw.pas for the TppReportTreeView class. Also check out the
TppCheckTreeView class in ppCheckTreeView.pas as an alternative. Visually,
you have to create the treeview in code in your custom preview (TppPreview)
descendent. You could show it in the panel below the outline or above it,
because the AccessoryToolbar (a TPanel) in the TppPreview parents the
Textsearch panel and the OutlineViewer.

Hey, that sounds good... i'll give it a try when i have some time
I don't really need it right now, but my customers will love such
feature because sometimes they just want to print/export some parts of
the report. So including this in a future report release will be great.
Thanks a lot
