Error using Report Viewer in ChildWindow

[Donald Hamm]

Below is the XAML I have for the viewer

<controls:ChildWindow x:Class="AssetManagement.ModuleImport.Views.ImportStatusViewer"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"

xmlns:telerik="clr-namespace:Telerik.ReportViewer.Silverlight;assembly=Telerik.ReportViewer.Silverlight"

xmlns:telerikNav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"

xmlns:telerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"

xmlns:telerikPrimitives="clr-namespace:Telerik.Windows.Controls.Primitives;assembly=Telerik.Windows.Controls"

xmlns:telerikInput="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input"

Width="600" Height="700"

Title="Import Status Viewer">

<Grid x:Name="LayoutRoot" Margin="2">

<telerik:ReportViewer x:Name="ReportViewer1"

Width="600" ReportServiceUri = "../ReportService.svc"

Report = "DuffPhelps.Reports.Import.ImportStatusForBatch, DuffPhelps.Reports.Import, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">

</telerik:ReportViewer>

</Grid>

</controls:ChildWindow>

When I try to 'show' the viewer, I get the following:
An unhandled exception ('Unhandled Error in Silverlight Application
 Code: 4004
Category: ManagedRuntimeError
Message: System.Windows.Markup.XamlParseException:
System.Windows.Markup.XamlParseException:

Possible Debuggers.....

If I put this in a 'UserControl', I don't get the error -- but, I want to use the child window for obvious reasons.
I'm using Silverlight 3, Q3 Reporting, and Q1 2010 SL 3 libraries.  I've even removed the url and report and it still give the same error...

Thanks!

The Silverlight viewer uses controls from RadControls for Silverlight, so the respective versions should always match. In your case you should upgrade Telerik Reporting to Q1 2010 as well. Having this article ("RadComboBox.SelectionBoxItemTemplate is read only" error in Silverlight viewer) in mind, it is recommended to download the latest internal builds of both product suites.
