I have the latest build of WPF Q2 SP1 and I am getting the following error:
A TwoWay or OneWayToSource binding cannot work on the read-only property 'xxx' of type 'TelerikTestProject.TestClass'. This error happens whenever I place the GridView inside of a Actipro PopupButton and then inside of a Actipro ResizableContentControl. If I take the RadGrid out of the control I don't get the error. I have a sample project I can send you to reproduce the error.

    
            <Window x:Class="TelerikTestProject.Window1" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                Title="Window1" Height="300" Width="300"   
        
                xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared" 
        
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
        
                    > 
        
                <Grid> 
        
                    <shared:PopupButton Grid.Column="1" HorizontalContentAlignment="Left" BorderThickness="0" BorderBrush="Transparent" PopupContent="{Binding}" VerticalContentAlignment="Center" Margin="0" Background="Transparent" IsRounded="True" DisplayMode="Merged">  
        
                        <shared:PopupButton.PopupContentTemplate> 
        
                            <DataTemplate> 
        
                                <shared:ResizableContentControl MinHeight="50" MinWidth="300" Padding="1" > 
        
                                    <telerik:RadGridView ItemsSource="{Binding Items}" AutoGenerateColumns="False" ShowGroupPanel="False">  
        
                                        <telerik:RadGridView.Columns> 
        
                                            <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Path=Comments}" UniqueName="{x:Null}"/>                                  
        
                                        </telerik:RadGridView.Columns> 
        
                                    </telerik:RadGridView> 
        
                                </shared:ResizableContentControl> 
        
                            </DataTemplate> 
        
                        </shared:PopupButton.PopupContentTemplate> 
        
                    </shared:PopupButton> 
        
                </Grid> 
        
            </Window>
