Hello all,

I have an SL4 LOB app that incorporates your reporting. When the view control loads, it is set to display a default reports (think splash page).
When I use the wizard upgrade and go from v6.1.12.611 (2012 Q2) to v7.1.13.612 (2013 Q2) the report no longer renders in the control and provides the following error:

Error: System.Windows.Markup.XamlParseException : The attachable property 'Action' was not found in type 'Interactivity'. [Line: 1 Position: 1631]
    at MS.Internal.XcpImports.CreateFromXaml(String xamlString, Boolean createNamescope, Boolean requireDefaultNamespace, Boolean allowEventHandlers, Boolean expandTemplatesDuringParse)
    at MS.Internal.XcpImports.CreateFromXaml(String xamlString, Boolean createNamescope, Boolean requireDefaultNamespace, Boolean allowEventHandlers)
    at System.Windows.Markup.XamlReader.Load(String xaml)
    at Telerik.ReportViewer.Silverlight.ReportViewerModel.GetUIElement(Byte[] buffer)
    at Telerik.ReportViewer.Silverlight.ReportViewerModel.OnPageLoaderPageLoaded(Object sender, PageInfoArgs e)
    at Telerik.ReportViewer.Silverlight.ReportViewerModel.PageLoader.OnPageLoaded(Object sender, PageInfoArgs args)
    at Telerik.ReportViewer.Silverlight.ReportViewerModel.PageLoader.OnGetPageCompleted(Object sender, GetPageEventArgs e)

The default report is set in XAML as follows:
<my:ReportViewer x:Name="ReportViewer" ReportServerUri="../Services/ReportService.svc" Height="600" Grid.Row="1" Grid.ColumnSpan="2" HorizontalAlignment="Stretch" VerticalAlignment="Top" Report="ReportLibrary.rptSplash, ReportLibrary" ZoomMode="PageWidth" />


The report renders within the VS design on the preview tab without issue.
A screen shot of how it renders in 2012 Q2 is attached.

Help is appreciated.

Hello,

This error usually happens when your Silverlight application is still using the old version of the Silverlight ReportViewer (i.e. you are not using the latest version of the viewer in the Silverlight application). Make sure that the reference is correctly updated and you have cleared the browser's cache. To make sure that this is not a caching issue, try to open the page in a different browser than the one in which the problem occurs.

Have you tried the new visualization options in Telerik Reporting Q2 2013? You can get them from your account.
