Empty Button in ReportViewer

[Chris Thierry]

HI, I'm using Telerik Reporting 5.1.11.928, in the Report Viewer toolbar, I have and empty button, and I don't know what it is.
Any Idea? Please check attached file.
Thank you.

This is the code xaml code:

<UserControl
    x:Class="Etelesolv.Telemanager.TME.UserControls.Invoice.InvoiceReportUC"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:my="clr-namespace:Telerik.ReportViewer.Silverlight;assembly=Telerik.ReportViewer.Silverlight"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    mc:Ignorable="d"
    d:DesignHeight="500" d:DesignWidth="400">

    <my:ReportViewer Name="ReportViewer1"
        HorizontalAlignment="Stretch"
        MinWidth="400"
        RenderBegin="ReportViewer1_RenderBegin"
        ReportServiceUri="../MyReportingService1.svc"
        Report="MyReport.Reporting.Invoice, MyReport.Reporting" UseNativePrinting="True" />
</UserControl>

Hi Chris,

In Q3 2011 we've introduced Interactive view and Print preview for all viewers (for more info see Interactive vs. Print Layout help article). To switch between both, you need to use the button you refer to as empty. As the template for the Silverlight report viewer is insight the RadControls for Silverlight controls, I suspect you have used newer version of those assemblies. To resolve the issue, please upgrade both Telerik Reporting and RadControls for Silverlight assemblies to be from the same Q e.g. Q3 2011. This guarantees that the viewer's template would match any new functionality we've added.

Kind regards,
Steve
