I have a problem changing a property of the RadTileView control (e.g. IsEnabled) using the properties panel. I get always an error message. I did the following steps:

1. Create a new WpfApplication
2. I dropped a RadExpander control
3. I dropped a RadTileView control
4. Select the RadExpander, click the IsEnabled property in the property panel
   à there is no problem
5. Select the RadTileView, click the IsEnabled property in the property panel
   à I get the message “Property value is not valid”

Error message in MainWindow:

Hi, there.
I think RadBook is a great component for document viewer.
The problem is that I need to change the Width and Height of the viewer and the contents need to reformat the pages to fit in.
I tested code based on "RadBookIntegration" sample by adding the follwoing code.

       private void RadButtonIncrease_Click(object sender, RoutedEventArgs e)
        {
            RadDocument doc = this.viewManager.Document;
            doc.DefaultPageLayoutSettings.Width += 50;
            doc.DefaultPageLayoutSettings.Height += 50;
            doc.UpdateLayout();
        }
        private void RadButtonDecrease_Click(object sender, RoutedEventArgs e)
        {
            RadDocument doc = this.viewManager.Document;
            doc.DefaultPageLayoutSettings.Width -= 50;
            doc.DefaultPageLayoutSettings.Height -= 50;
            doc.UpdateLayout();
        }

I believe UpdateLayout should reformat the contents but the result is not what I expected;  page numbers and contents gets duplicated.
Can you please tell me what I'm doing wrong?

Thanks for your help.
