New Post: GridControl ComboBox editor

I have LIst of the Items that assigned to ItemsSource of the ComboBox. Right now almost everything is working like I need. But I can't understand why ComponentId is not updating.

<xcdg:Column Title="Title" Width="300" FieldName="ComponentId">

                                    <xcdg:Column.CellContentTemplate>
                                        <DataTemplate>
                                            <ComboBox
                                                        HorizontalAlignment="Stretch"
                                                        VerticalAlignment="Center"
                                                        DisplayMemberPath="Name"
                                                        ItemsSource="{Binding RelativeSource={RelativeSource AncestorType={x:Type views:BunkerEditView}}, Path=DataContext.ComponentList}"
                                                        SelectedValue="{xcdg:CellEditorBinding}"
                                                        IsEnabled="{Binding ElementName=BunkerEditWindow, Path=DataContext.SelectedItem.CanChangeContent}"
                                                        SelectedValuePath="Id"/>
                                        </DataTemplate>
                                    </xcdg:Column.CellContentTemplate>
                                </xcdg:Column>

I tried to use CellEditor, but then it will show me GUID of the Component instead of the Name.

Thanks a lot for the help.
