GetReportParameters ignores language="en-gb"?

Hello

I've integrated my reports into an app using the ReportViewer control, and I've created custom parameter selection controls. I want the user to be able to enter dates in dd/mm/yy format into a textbox. I've set the language of my reports to en-gb.

The SetParametes method of the ReportViewer control copes with this fine, but when I pass a date string in dd/mm/yy format into GetReportParameters, I get a 'parameter value not valid for its type' error. But it works for date strings in mm/dd/yy format, so it's as if GetReportParameters is ignoring my language setting.

Has anyone got any idea as to where I'm going wrong?

Thanks in advance

Dominic

After a little more playing around with this I've found that, on my machine, the SetParameters method always wants dates in dd/mm/yy format, whilst the GetReportParameters web method of the Report Service always wants dates in mm/dd/yy format, regardless of what I set the language of the report to.

Does anyone know what's going on?
