c# - 如何将列表绑定(bind)到 Data Grids 数据源的子类中的组合框？

Question

到目前为止，这是我的 DxGrid 代码:

<dxg:GridControl x:Name="gridControlItemsDistinct" 
                             VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
                             Height="Auto" Width="Auto"
                             AutoPopulateColumns="False"
                             DataSource="{Binding Path=ChaseListHelperClassItemsList, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
<dxg:GridControl.Columns>
    <dxg:GridColumn FieldName="CreativeContactID" Header="Creative Contact Name" Width="90" FilterPopupMode="CheckedList" AllowEditing="True">
        <dxg:GridColumn.EditSettings>
            <dxe:ComboBoxEditSettings Name="cboCreativeContact"
                            DisplayMember="ContactName" 
                            AutoComplete="True" 
                            ValueMember="ContactID" 
                            ItemsSource="{Binding Path=Data.CreativeAgContactList, UpdateSourceTrigger=PropertyChanged}" />
        </dxg:GridColumn.EditSettings>
        <dxg:GridColumn.CellStyle>
            <Style TargetType="{x:Type dxg:CellContentPresenter}">
                <Setter Property="Background" Value="#FFE8F2F3" />
                <Setter Property="TextBlock.Foreground" Value="Black" />
            </Style>
        </dxg:GridColumn.CellStyle>
    </dxg:GridColumn>
</dxg:GridControl.Columns>

如您所见，我的网格绑定(bind)到 ChaseListHelperClassItemsList :

public List<CreateChaseListHelperClass> ChaseListHelperClassItemsList
    {
        get 
        {
            return chaseListHelperClassItemsList; 
        }
        set
        {
            chaseListHelperClassItemsList = value;
            OnPropertyChanged("ChaseListHelperClassItemsList");
        }
    }

创建ChaseListHelperClass:

    public class CreateChaseListHelperClass
    {
        private int creativeContactID;

        public int CreativeContactID
        {
            get;
            set;
        }

        public IQueryable<Contacts> CreativeAgContactList
        {
            get;
        }
    }

我的问题是，如何绑定(bind) cboCreativeContact ItemSource 到我的 CreateChaseListHelperClass 中的列表, CreativeAgContactList .

我当前的绑定(bind)如下所示:

ItemsSource="{Binding Path=Data.CreativeAgContactList, UpdateSourceTrigger=PropertyChanged}"

我的 DataContext 在我的 View 中设置:

DataContact = ChaseListViewModel

所以结构是

ChaseListViewModel-CreateChaseListHelperClassList-CreativeAgContactList

我想设置 CreateAgContactList作为 ItemSource在我的组合框上

我们去吧。使用单元格模板:

<dxg:GridColumn FieldName="CreativeAgContactID" Header="Creative Contact Name" Width="90" FilterPopupMode="CheckedList" AllowEditing="True">
                    <dxg:GridColumn.CellTemplate>
                        <DataTemplate>
                            <dxe:ComboBoxEdit Name="cboCreativeContact" 
                                              DisplayMember="ContactName"
                                              ValueMember="ContactID"
                                              AutoComplete="True" 
                                              EditValue="{Binding Path=ContactID, UpdateSourceTrigger=PropertyChanged}"
                                              ItemsSource="{Binding Path=Data.CreativeAgContactList, UpdateSourceTrigger=PropertyChanged}">                                    
                            </dxe:ComboBoxEdit>
                        </DataTemplate>
                    </dxg:GridColumn.CellTemplate>
                    <dxg:GridColumn.CellStyle>
                        <Style TargetType="{x:Type dxg:CellContentPresenter}">
                            <Setter Property="Background" Value="#FFE8F2F3" />
                            <Setter Property="TextBlock.Foreground" Value="Black" />
                        </Style>
                    </dxg:GridColumn.CellStyle>
                </dxg:GridColumn>
