    text
    copied!<p>I’ve got a ribbon combobox (MS Ribbon OpenSource project, .Net 4.0) which is data bound to a property of my viewmodel like this:</p> <p><em>XAML</em>:</p> <pre><code>&lt;ribbon:RibbonComboBox SelectionBoxWidth="130" Margin="3,0"&gt; &lt;ribbon:RibbonGallery SelectedValue="{Binding Source={StaticResource ViewModel}, Path=Document, Converter={StaticResource DocumentToDocumentNameConverter}, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"&gt; &lt;ribbon:RibbonGalleryCategory ItemsSource="{Binding Source={StaticResource ViewModel}, Path=Documents, Converter={StaticResource DocumentToDocumentNamesConverter}}"&gt; &lt;/ribbon:RibbonGalleryCategory&gt; &lt;/ribbon:RibbonGallery&gt; &lt;/ribbon:RibbonComboBox&gt; </code></pre> <p><em>ViewModel</em>:</p> <pre><code>public ViewModel { #region Fields private TestDocument _Document; #endregion #region Properties public TestDocument Document { get { return ModelClass.SelectedDocument; } set { if (value != null &amp;&amp; value != _Document) { _Document = value; OnPropertyChanged("Document"); } } } #endregion } </code></pre> <p>That works good, if I select another value in the ComboBox the converter is entered and the value shown.</p> <p>But if I set the property in the ViewModel like this</p> <pre><code>Document = new TestDocument("DocumentName"); </code></pre> <p>the ComboBox doesn't show the name as selected.</p> <p>Do you have any suggestions? I've even tried to bind SelectedItem instead of SelectedValue but this doesn't fixed the problem. Have I forgotten something?</p>
