I don?t want print header group with no detail

rbuser

Hi,

Delphi 5 Enterprise
Rep.builder 6.03

How can I disable printing header group when I haven?t detail?

My report detail is conditional.

Thanks in advance

When are you setting the detail band visibility? If the group header has
already printed, then you are out of luck. The only way to fix this is to
remove the draw commands associated with the header band, when the current
page generation is complete. Create a TList. For each component in the
group header band, use their OnDrawCommandCreate event to stick them inside
of a TList. Then in the Report.OnEndPage event, you can loop through the
TList and remove these draw commands from the page.

...
var
lPage: TppPage;

begin
...
lPage := Report.Engine.Page;

for liIndex := 0 to myTList.Count - 1 do
begin
lDrawCommand := TppDrawCommand(myTList[liIndex]);
lPage.RemoveDrawCommand(lDrawCommand);
end;
