Binding a WPF DataGridComboBoxColumn with MVVM

by

Here is a working code. The key point here was to use SelectedValueBinding instead of SelecteItemBinding. 

<DataGridComboBoxColumn Header="Title" 
                        SelectedValueBinding="{Binding TitleId}"
                        SelectedValuePath="TitleId"
                        DisplayMemberPath="TitleText"
                        >
    <DataGridComboBoxColumn.ElementStyle>
        <Style TargetType="ComboBox">
            <Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.Titles}"/>
        </Style>
    </DataGridComboBoxColumn.ElementStyle>
    <DataGridComboBoxColumn.EditingElementStyle>
        <Style TargetType="ComboBox">
            <Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.Titles}"/>
        </Style>
    </DataGridComboBoxColumn.EditingElementStyle>
</DataGridComboBoxColumn>
