title: Push some ObservableCollection items in a GridControl into another ObservableCollection XAML
body: <p>I'd like to bind an ObservableCollection to a DevExpress GridControl but it's not working...</p>
  
  <p>My XAML code:</p>
  
  <pre><code>     &lt;dxg:GridColumn Header="Categorie" FieldName="SelectetProgrammCategorieIds"&gt;
                      &lt;dxg:GridColumn.EditSettings&gt;
                          &lt;dxe:ComboBoxEditSettings ItemsSource="{Binding AlleCategorien, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" ValueMember="ID" DisplayMember="Name"&gt;
                              &lt;dxe:ComboBoxEditSettings.StyleSettings&gt;
                                  &lt;dxe:CheckedComboBoxStyleSettings/&gt;
                              &lt;/dxe:ComboBoxEditSettings.StyleSettings&gt;
                          &lt;/dxe:ComboBoxEditSettings&gt;
                      &lt;/dxg:GridColumn.EditSettings&gt;
                  &lt;/dxg:GridColumn&gt;
  </code></pre>
  
  <p>SelectetProgrammCategorieIds is an OBC and AlleCategorien is my list with All Categories. I want do separate and load some marked items from AlleCategorien into SelectetProgrammCategorieIds</p>
