I am developing an application and I am using from some libraries, the Ribbon of Microsoft. At one point, I carried the information on the component, but can not seem to set the initial value. Follows the code:

<r:RibbonComboBox 
    x:Name="rcbFontFamily" 
    SelectionBoxWidth="160"
    IsEditable="True">
    <r:RibbonGallery
        Name="_rgFontFamily"
        ScrollViewer.VerticalScrollBarVisibility="Visible"
        Command="{StaticResource FontFamilyHandler}">
        <r:RibbonGalleryCategory
            Name="_rgcFontFamily"
            ItemsSource="{Binding Source={x:Static Fonts.SystemFontFamilies}}"/>
    </r:RibbonGallery>
</r:RibbonComboBox>

I can set the value by mouse click, but I can not bring the combobox with an initial value. How to do this?

  • Yes, but I could not adapt to my case. I can set the value by mouse click, but I can not bring the combobox with an initial value. – Paulo Freitas Jan 12 '16 at 12:40
