Hide group headers when no details.

rbuser

I need to hide the group headers (multiple groups) when there is no detail
data. I found this post:

from Jim Bennett of Digital meaphors:
Something like this should do the trick:

but this file no longer exists there, do you still have this demo file?

Thanks,

Hi Rob,

The link should work correctly now. Sorry for the inconvenience.

Thanks, the only problem is I must be a little dense today.

From looking at the project, it looks like you are trying to hide the detail
band if the CustomerID is 1221, then in the second pass hide the Group
header if the detail band is not visible.

But the project still prints the the header for 1221 and all the records
that go with it. So I must not understand the purpose of this project.

Could you let me know what it is supposed to do?

Thanks in advance,
Rob

Hi Rob,

Sorry about that, I didn't look at the example, only fixed the link .

After taking a look it seems this example is not doing what you need. The
issue is that ReportBuilder traverses the data as the report is generated,
preventing you from finding out if there is no data for a group before the
repor is generated. A couple things you might try are...

1. Pre-process you data and determine which groups have no data before the
report is printed and hide those groups as needed.

2. In the DetailBand.BeforePrint event (perhaps) count how many detail
bands are generated per group in the first pass of the report. If, when the
group footer is printed, the count is 0, hide the group header for the
second pass.
