.Net ReportViewer shows wrong group names in the navigation group tree !?

[Former Member]

Hallo,

I have reports where everything run ok, by developing and testing in Crystal Reports Designer 2008.

But later, the same reports, will be run and displayed in an Visual Studio 2005 .NET Application using CrystalDecisions.Windows.Forms.CrystalReportViewer (12.0.2000.0).

Here are the displayed group names in the navigation group tree WRONG. Drill-Down still works when i double-click any "wrong" group name, and I get instead, the "correct" group name displayed within my drill-down. There must something go wrong by setting the group names in the group tree, because everything else (group count, total sums and count) looks correct.

please help !

Sorry TristaL,

i try one more time:

Correct - in Report Designer

2008.08
    * HELPLINEPORTAL
    * IMPORT
    Auftragsmanagement
    First Level
    First Level <= 10 min
    Second Level
    Second Level > 10min
    Technik / Außendienst
    Third Level
2008.09
    * HELPLINEPORTAL
    * IMPORT
    Auftragsmanagement
    First Level
    First Level <= 10 min
    Second Level > 10min

WRONG - in Report Viewer

2008.08
	* IMPORT

That's strange. I haven't heard of this before. Is this the only report you see this behavior with? What version of CR was the report originally designed in, and what version are the CrystalDecisions.* references in your project?

One thing that comes to mind is special characters - do you have anything besides stars in your group headers (escape sequences, RTF codes, etc)?

Are you able to reproduce the behavior with a new report?

Hi TristaL,

thanks for your advice: as i recreate the report entirely from scratch, under report designer 12, there was no problem more later in report viewer to see.

We have a lot more reports with this behaviuor. I think all those reports have been more as once upgraded:

cr8.5 -> cr 9.0 -> cr10 -> cr11 -> cr12.

We have for our product a "ReportPack" containing cca 120 reports. When our customers wish a extra report for their special needs, we change very oft one "old" report in the direction the customer wish to.

"Recreate each report with this problem from scratch." - this would be a very annoying workaround.

Report designer is already smart enough to work with those "old" reports. Bur report viewer has a problem with them.

There must be a better workaround for this problem !

Hi Tristan,

Thank you for your interes. I miss a posibility to insert screenshots in this thread.

Here are the 2 group trees as text overview. Personally, i can not recognize any pattern, for me is this randomly.

Correct - in Report Designer				WRONG - in Report Viewer

2008.08								2008.08
	* HELPLINEPORTAL						* IMPORT
	* IMPORT								* IMPORT
	Auftragsmanagement						Second Level
	First Level								* IMPORT
	First Level <= 10 min					       Second Level
	Second Level							Second Level > 10min
	Second Level > 10min					Second Level
	Technik / Außendienst					Second Level > 10min
	Third Level								Second Level > 10min
2008.09								2008.08
	* HELPLINEPORTAL						Second Level
	* IMPORT								Second Level > 10min
	Auftragsmanagement						Second Level > 10min
	First Level								Second Level > 10min
	First Level <= 10 min					        Second Level > 10min
	Second Level > 10min					Second Level > 10min

Please define "wrong" in the context of your issue. What's the difference between what actually appears and what you expect to see in the group tree? Do you see any patterns?
