I am using VS2010B2 with the Telerik Silverlight 4 beta controls and I am having trouble getting data from WCF RIA Services in a very simple XAML file. The same XAML file hooks up to Silverlight's DataGrid just fine but fails with no exceptions in the Telerik RadGridView. The RadGridView just shows up with no column headers and a gray background. The busy image seems to work fine while retrieving data. Also when I have a DataPager bound to the data source, the busy image on the Telerik control would show for a split second while paging.

Here's the XAML:

    
                <Grid x:Name="LayoutRoot" Background="White">  
        
                    <ria:DomainDataSource x:Name="domainDataSource" AutoLoad="True" QueryName="GetOrders">  
        
                        <ria:DomainDataSource.DomainContext> 
        
                            <web:OrdersContext /> 
        
                        </ria:DomainDataSource.DomainContext> 
        
                    </ria:DomainDataSource> 
        
                    <StackPanel> 
        
                        <tgrid:RadGridView x:Name="dataGrid" Height="150" ItemsSource="{Binding Data, ElementName=domainDataSource}" 
        
                                               IsBusy="{Binding IsLoadingData, ElementName=domainDataSource}" /> 
        
                        <data:DataGrid x:Name="anotherDataGrid" Height="150" ItemsSource="{Binding Data, ElementName=domainDataSource}" /> 
        
                    </StackPanel> 
        
                </Grid>

Hi Scott,

We have some problems with RIA Services and SL4 in the past, but they have been fixed. I'm attaching a new version of the dlls build against SL4. Can you please verify the state of the problem against it?

All the best,

I think I spoke too soon about the fix with the new DLLs. My project also has a RibbonBar on it and now I'm getting compilation errors like:
The tag 'RadRibbonBar' does not exist in XML namespace 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.RibbonBar'.
on top of this error I'm getting VS2010 crashes too. the exception stack is:
System.NotImplementedException: The method or operation is not implemented.
