Необработанное исключение при добавлении RibbonGroup

1 голос
/ 25 марта 2011

Я пытаюсь реализовать ленту Outlook в приложении WPF, и лента работает нормально. Однако, когда я пытаюсь добавить RibbonGroup, я получаю необработанное исключение в XAML.

Вот мой код: 

<r:RibbonWindow 
    x:Class="WpfArticles.Main"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
    Title="Main" Height="500" Width="500">

    <StackPanel>
        <r:Ribbon Title="WPF Ribbon - Document1" x:Name="ribbon" >
            <r:RibbonTab Label="Home">
                <r:RibbonGroup Name="Test" />
            </r:RibbonTab>
            <r:RibbonTab Label="Insert"/>
            <r:RibbonTab Label="Help"/>
        </r:Ribbon >

и я получаю эту ошибку в XAML:

Что я делаю не так? Без <r:RibbonGroup Name="Test" /> работает нормально!

Спасибо за вашу помощь и время

Я скачал эту ленту, но по какой-то причине не смог добавить ссылку.Во всяком случае, я скачал пример, и в нем четко сказано, что группа сгенерирует исключение, если оно будет пустым.Так что теперь все работает отлично.Спасибо за вашу помощь!

Я подозреваю, что вы используете более старую версию, поскольку свойство Label больше недействительно.Последнюю версию можно найти здесь .
