Hi,

what is the correct way to show multiple reports in a separate thread each?
The reason is that we use modal windows, and when you show a report in a window and change to a different window, the open report is not responsive any more.
When shown in an own thread, it is.

In Reports.NET we used this code, which worked fine:

public static void ShowReport(StiReport rpt) //rpt already filled with data and rendered
{
if (rpt == null) return;

Thread threadShowReport = new Thread(new ParameterizedThreadStart(ShowReport));
threadShowReport.SetApartmentState(ApartmentState.STA);
threadShowReport.IsBackground = true;
threadShowReport.Start(rpt);
}

public static void ShowReport(object obj)
{
((StiReport)obj).Show(true);
}

Recently we changed to Reports.WPF, and on the second call an exception is thrown:
"the calling thread cannot access this object because a different thread owns it"

Please help!

Hello,

In your sample, you should change ShowDialog() on the Show() method.

Thank you.

I know this would work
But we need ShowDialog in certain cases...
