Report-Designer and WPF?

leSasch

Hi,

is it possible to use the reportdesigner-control in an WPF-App?
I'm trying to embed it in a WindowsFormsHost - it gets created fine so far.
But when I try to attach a report for designing, there's a null reference exception:

{System.NullReferenceException: Object reference not set to an instance of an object.

My code is only:
var report = new Report();
report.Load(@c:\users\sas.zeteko\desktop\easyFact.DNF-DE.frx);
this.ReportDesigner.Report = report; <-- here's the exception thrown

Maybe you can help?`

Thanks
