expanding drill down reports programatically, via an end user report viewer?

rbuser

hi everyone,

at the point of loading a report into the end-user report viewer, is there a
way to collapse/expand individual drill down components; as opposed to the
expanddrilldowns/collapsedrilldowns; which does all...

i want to offer the user the option of drilling down at the application user
interface level.

tia,

Sorry, for the delay, you'll need to pull out the expansion key for the
currently printing subreport and add it to the expansions list which the
subreport has. At report generation time, the expansion key for a subreport
can be extracted. You can do this in the OnPrint event of the subreport
component. You'll want to call this method based on whichh subreport you
want to expand on the page.

if (FCount = 3) then
Subreport.AddExpansion(Subreport.GetExpansionKey);

This will cause the third subreport to expand, while the others aren't
expanded. The report engine will take care of the rest for you, because it
uses the expansion list of the subreport to generate.
