                            <Style TargetType="Popup">
                                <Setter Property="TextElement.Foreground"

                            </Style>
                        </ComboBox.Resources>
                        <system:String>A</system:String>
                        <system:String>BIN</system:String>
                        <system:String>BOOL</system:String>
                    </ComboBox>
                </DataTemplate>
            </xcdg:CellEditor.EditTemplate>

Just replace your

<ComboBox ItemsSource="{Binding Path=DataTypes}"

 with

<TextBlock Text="{Binding FallbackValue=UNBOUND, TargetNullValue=NULL}"

 to see where the problems lies.

(The binding will be either NULL or the value of your column; both being useless)
