Hello,

I have an RichTextBox with ad RichTextBoxRibbonUI.
I implemented the "Orientation" - DropDownButton similar to the Silverlight Demo (http://demos.telerik.com/silverlight/#RichTextBox/TelerikEditor) like this:

<Controls:RadRibbonDropDownButton CollapseToMedium="WhenGroupIsMedium" Command="{Binding Path=ChangePageOrientationCommand}" LargeImage="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/PageOrientation.png" Controls:ScreenTip.Description="Switch the pages between portrait and landscape layouts." Controls:ScreenTip.Title="Page Orientation" Size="Medium" Text="Orientation">
                                    <Controls:RadRibbonDropDownButton.DropDownContent>
                                        <Controls:RadGallery ItemHeight="54" ItemWidth="109" RichTextBoxUI:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=ChangePageOrientationCommand}" ViewportHeight="216" ViewportWidth="110">
                                            <Controls:RadGalleryItem HorizontalContentAlignment="Left" Tag="Portrait">
                                                <StackPanel Orientation="Horizontal">
                                                    <Image Source="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/PageOrientationPortrait.png" Stretch="None" />
                                                    <TextBlock FontWeight="Bold" Text="Portrait" VerticalAlignment="Center" />
                                                </StackPanel>
                                            </Controls:RadGalleryItem>
                                            <Controls:RadGalleryItem HorizontalContentAlignment="Left" Tag="Rotate90">
                                                <StackPanel Orientation="Horizontal">
                                                    <Image Source="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/PageOrientationLandscape.png" Stretch="None" />
                                                    <TextBlock FontWeight="Bold" Text="Landscape" VerticalAlignment="Center" />
                                                </StackPanel>
                                            </Controls:RadGalleryItem>
                                            <Controls:RadGalleryItem HorizontalContentAlignment="Left" Tag="Rotate180">
                                                <StackPanel Orientation="Horizontal">
                                                    <Image Source="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/PageOrientationRotate180.png" Stretch="None" />
                                                    <TextBlock FontWeight="Bold" Text="Rotate 180" VerticalAlignment="Center" />
                                                </StackPanel>
                                            </Controls:RadGalleryItem>
                                            <Controls:RadGalleryItem HorizontalContentAlignment="Left" Tag="Rotate270">
                                                <StackPanel Orientation="Horizontal">
                                                    <Image Source="/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/PageOrientationRotate270.png" Stretch="None" />
                                                    <TextBlock FontWeight="Bold" Text="Rotate 270" VerticalAlignment="Center" />
                                                </StackPanel>
                                            </Controls:RadGalleryItem>
                                        </Controls:RadGallery>
                                    </Controls:RadRibbonDropDownButton.DropDownContent>
                                </Controls:RadRibbonDropDownButton>

The problem is that the Button is always disabled.
Is there any condition which prevents the button to be enabled?

Regards,

Bastian Kraehmer

Hi Bastian Kraehmer,

Having set the attached property RichTextBoxUI:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=ChangePageOrientationCommand}", the button must be disabled when the CanExecute of the command returns false.

The only condition that makes the CanExecute of ChangePageOrientationCommand return false is if the rich text box is used in read-only mode.

Please find attached a demo project which uses the code from your snippet and works as expected. If you are not able to resolve the issue in your project, please attache a demo of yours in the support ticket you opened, so that we can assist you further.

Hello tarun,

It does not become clear what might be the cause of the issue. You can see a working SDK demo where the page orientation has been properly here - Telerik Editor.
