hi,
I'm trying to view a report in StiWebViewerSL, and I have no errors in debug time, but at run time this happens:

Exception occurred during the execution (yellow page)
[NullReferenceException: Object reference not set to an instance of an object.]
Stimulsoft.Base.StiExceptionForm..ctor(Exception exception) +754
Stimulsoft.Base.StiExceptionProvider.Show(Exception exception) +116
Stimulsoft.Report.Dialogs.StiWinDialogsProvider.RenderForm(IStiForm formControl) +402
Stimulsoft.Report.Dialogs.StiWinDialogsProvider.Render(StiReport report, StiFormStartMode startMode) +245
Stimulsoft.Report.Engine.StiRenderProviderV2.RenderFormsOnStart(StiReport report) +128
Stimulsoft.Report.Engine.StiRenderProviderV2.Render(StiReport report, StiRenderState state) +5907
Stimulsoft.Report.Engine.StiReportV2Builder.RenderSingleReport(StiReport masterReport, StiRenderState renderState) +1227
Stimulsoft.Report.StiReport.RenderReport(StiRenderState renderState) +2037
Stimulsoft.Report.StiReport.Render(StiRenderState renderState, StiGuiMode guiMode) +943
Stimulsoft.Report.WebSL.StiWebViewerSL.set_Report(StiReport value) +280

I think it has something to do with loading assemblies that RenderForm method is depended on. any idea?
thanks in advanced.

aspx code:

Code: Select all

<body>

    <form id="Reportform" runat="server">
        <cc1:StiWebViewerSL ID="stiViewer" runat="server" Width="100%" Height="700" AutoMaximize="true" />
    </form>

</body>

Code: Select all

//do some business stuff

// instance which creates Stimulsoft report document
var marshal = ReportMarshal.CreateInstance("BusinessLayer.FGReportMarshal"); 
 
//generates Stimulsoft report and registers data
var requestID = marshal.RequestReportView(businessreport, authenticationInfo, dataLimitation, dataFilters);
 var reportFile = marshal.GetReport(requestID);

stiViewer.Report = reportFile.ReportFileDocument as StiReport;

Hello.

At first, please, try to upgrade to the latest release.
Let us know if you still get the same error.

Thank you.

tanks for the reply,
OK, after updating to 14.3 exception message changed to:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

Hello.

Sorry for previous wrong advice.
The Forms are not supported in Silverlight.

Thank you.
