Dev GridControl 级联显示问题

Panke 2014-11-14 08:34:12

这里用的是Dev 的 WPF 版本 GridControl控件，给控件添加了2列，分别绑定省份和城市。现在想要在选择省份的时候城市那列自动过滤出对应省份的城市供选择，不知道如何实现。求大神指教



<dxg:GridControl   ItemsSource="{Binding Model.OrderDetailsList}"

                <dxg:GridControl.Columns>

                    <dxg:GridColumn FieldName="ProvincesID" Header="省份" >

<dxg:GridColumn.EditSettings>

                            <dxg:LookUpEditSettings ShowSizeGrip="True" DisplayMember="Number" ValueMember="ID" 

                                                    ItemsSource="{x:Static nsStaticModel:Provinces}"

                                                    PopupContentTemplate="{StaticResource Res_BankAcountGridControl}" IncrementalFiltering="False" ImmediatePopup="False">

                            </dxg:LookUpEditSettings>

                        </dxg:GridColumn.EditSettings>

                     </dxg:GridColumn>

                    <dxg:GridColumn FieldName="CityID" Header="城市" >

                        <dxg:GridColumn.EditSettings>

                            <dxg:LookUpEditSettings ShowSizeGrip="True" DisplayMember="Number" ValueMember="ID" 

                                                    ItemsSource="{x:Static nsStaticModel:City}"

                                                    PopupContentTemplate="{StaticResource Res_BankAcountGridControl}" IncrementalFiltering="False" ImmediatePopup="False">

                            </dxg:LookUpEditSettings>

                        </dxg:GridColumn.EditSettings>

                    </dxg:GridColumn>

</dxg:GridControl.Columns>

                <dxg:GridControl.View>

                    <dxg:TableView  NewItemRowPosition="Bottom" />

                </dxg:GridControl.View>

            </dxg:GridControl>
