Pass optional parameters to CrystalReportViewer.ParameterFieldInfo

[Former Member]

Hi,

I have a report with three optional parameters. I want to provide the CrystalReportViewer with information so that it does *not* show the parameter dialog (or rather, does not request any optional parameters).

I tried just adding all parameters to the ParameterFieldInfo collection, but it prompts the missing "CurrentValues" despite the fact that the parameters are optional. What do I need to add to the ParameterFieldInfo collection so that it does not ask for optional parameters of my choice?

Any ideas?

Regards,

Florian

Please see if these help.

Thanks, the first link did indeed solve my problem. Google didn't bring that up unfortunately (but it does now thanks to this topic).

Hello Florian

Darn Google

Remember you can also try the search box in the top right of this web page. It's often not as good as Google, but this time it did the trick.

Happy coding,
