WPF中dxg:GridControl控件的GridColumn对象如何绑定对象的对象的字段


<dxg:GridColumn x:Name="colDataType" FieldName="FieldDataType" Header="Data Type" 
                            DisplayMemberBinding="{Binding Path=RowData.Row.FieldDataType.name, RelativeSource={RelativeSource Self} }" HorizontalHeaderContentAlignment="Center" 
                            BestFitMode="AllRows" BestFitArea="Rows" HorizontalAlignment="Right" Fixed="Right" FixedWidth="True"
                            MinWidth="100" />用这个就行了RowData.Row
