    Hi, I am using Silverlight 3 Book control version 2010.1.309.1030.  There seems to be a delay in animation when turning the book pages. I don't get this delay when I try your demo. To be certain I created a separate solution with a single page that contains the following xaml and I get the same delayed animation when turning pages.

    <UserControl x:Class="SilverlightApplicationBook.MainPage" 
               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation">  
        <Grid x:Name="LayoutRoot" Background="Purple">  
            <telerikNavigation:RadBook Margin="50">  
                <telerikNavigation:RadBookItem Background="Red">  
                    <TextBlock Text="Page 1" FontSize="36"/>  
                </telerikNavigation:RadBookItem> 
                <telerikNavigation:RadBookItem Background="BlueViolet">  
                    <TextBlock Text="Page 2" HorizontalAlignment="Right" FontSize="36"/>  
                </telerikNavigation:RadBookItem> 
                <telerikNavigation:RadBookItem Background="RosyBrown">  
                    <TextBlock Text="Page 3" FontSize="36"/>  
                </telerikNavigation:RadBookItem> 
                <telerikNavigation:RadBookItem Background="Chocolate">  
                    <TextBlock Text="Page 4" HorizontalAlignment="Right" FontSize="36"/>  
                </telerikNavigation:RadBookItem> 
            </telerikNavigation:RadBook> 
        </Grid> 
    </UserControl> 


    Thank You,
    Mike

    Hi Mike,

    Have you installed the Silverlight 4 plugin? If that is the case, I'd suggest you download 422 version of our controls where the animation issue has been fixed. Give it a try and let me know how it goes.

    Hi! I have a similar problem with the radbook. If I use the same code as above, the animation is delayed or "choppy". I'm using the Silverlight 4 controls from August 2010.

    Hello David,

    We are not aware of any existing performance issues. I've recorded a video demonstrating the above scenario. Please find attached a sample test project as well as a video recording. Have a look at it and let me know how I can be of further assistance.

    Best wishes,

    Thanks for answering. I tested the attached solution. While the performance is slightly bettre than my own project, it's still not as good as in your video. I tested my problem on two computers with completly different hardware profile but the result is the same...

    One thing I don't understand, when I run the RadBook from your demo section, it runs perfectly smooth, but not the control to it's most basic form.

    Hi David,

    Could you please try and isolate the issue in a separate project and send us this project. This way we will be better able to assist you. Also it would be great if you can record a video showing the performance issue you experience on your end.

    I tracked down the issue. It has nothing to do with your control. When I run the website on battery on my laptop, it runs fine. When I plug it, I have a lag. I don't understand it yet, but the issue is probably hardware related.

    Sorry I bothered you with that and thanks for you assistance.
