RadRichTextBox binding ViewModel to RadRibbonBackstageItem

[Tom]

Hi,

I have a problem with bindning command (which is in parent ViewModel) to RadRibbonBackstageItem.

<UserControl x:Class="Project.TelerikEditor"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             xmlns:telerikViewModel ="clr-namespace:Project.Modules.TelerikEditor.ViewModel"
             xmlns:optionsViewModel="clr-namespace:Project.Modules.Options.ViewModel"
             d:DesignHeight="300"
             d:DesignWidth="900"
             mc:Ignorable="d" >
   <UserControl.DataContext>
        <telerikViewModel:TelerikEditorViewModel/>
    </UserControl.DataContext>

...........

...........

...........

<telerik:RadRibbonBackstageItem Header="Options"
                                                    Icon="{telerik:IconResource IconRelativePath=16/new.png,
                                                                                IconSources={StaticResource IconSources}}"
                                                    DataContext="{Binding DataContext, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Mode=TwoWay}"
                                                    Command="{Binding OptionsWindowCommand }""
                                                    IsSelectable="false"
                                                    >

The Command don't pass to ViewModel.

Any suggestion?

Hi Tom,

 RadRibbonBackstageItem Command property should point to any of the commands in RadRichTextBox.Commands property, e.g. RadRichTextBox.Commands.NewDocumentCommand. So most probably in your case you would have to change DataContext to point to RadRichTextBox.Commands instance, instead of to UserControl.DataContext.
