You can try something like this:

<Grid>
<Grid.Resources>
 <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
                                    Source="{Binding Source={x:Static Application.Current},
                                              Path=Orders}">
 </xcdg:DataGridCollectionViewSource>

 <local:StringToPasswordConverter x:Key="stringToPasswordConverter" />
 
 <xcdg:CellEditor x:Key="passwordEditor">
    <xcdg:CellEditor.EditTemplate>
       <DataTemplate>
          <xcdg:AutoSelectTextBox Text="{xcdg:CellEditorBinding}" />
       </DataTemplate>
    </xcdg:CellEditor.EditTemplate>
 </xcdg:CellEditor>

 <DataTemplate x:Key="passwordDataTemplate">
    <TextBlock Text="{Binding Converter={StaticResource stringToPasswordConverter}}" />
 </DataTemplate>

</Grid.Resources>
<xcdg:DataGridControl x:Name="OrdersGrid"
                    ItemsSource="{Binding Source={StaticResource cvs_orders}}">
 <xcdg:DataGridControl.Columns>
    <xcdg:Column FieldName="ShipCountry"                      
                 CellContentTemplate="{StaticResource passwordDataTemplate}"
                 CellEditor="{StaticResource passwordEditor}"/>
 </xcdg:DataGridControl.Columns>
</xcdg:DataGridControl>
</Grid>
