首先，感谢您抽出宝贵时间阅读这篇文章。非常感谢所有贡献。

我很难理解如何将 DataTemplate 中的 ComboBox ItemsSource 绑定到 ObservableCollection。

到目前为止，这是我的代码：

DataTemplate 模板（注意模板底部的组合）：

<DataTemplate x:Key="ListBoxCustomTemplate">

            <Grid Margin="4" HorizontalAlignment="Stretch" x:Name="lstBoxItemRoomGrid" >
            <Grid.ColumnDefinitions>
                <ColumnDefinition />
                <ColumnDefinition />
            </Grid.ColumnDefinitions>

            <Grid.RowDefinitions>
                <RowDefinition />
                <RowDefinition />
                <RowDefinition />
                <RowDefinition />
            </Grid.RowDefinitions>

            <TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" FontWeight="Bold" Text="{Binding TemplateGroupName}" />

            <Image x:Name="imgDeleteListBoxItem" Grid.Row="0" Grid.RowSpan="2" Grid.Column="1" Source="/Icons/Print-Groups-Config/delete-32.png" Height="25" Cursor="Hand"
                   ToolTip="Remove template" VerticalAlignment="Center"
                   HorizontalAlignment="Right" MouseLeftButtonUp="imgDeleteListBoxItem_MouseLeftButtonUp">
                <Image.Style>
                    <Style>
                        <Setter Property="Image.Visibility" Value="Hidden" />
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding IsMouseOver, ElementName=lstBoxItemRoomGrid}" Value="True">
                                <Setter Property="Image.Visibility" Value="Visible" />
                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </Image.Style>
            </Image>

            <TextBlock Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Text="{Binding TemplateDescription}" TextWrapping="WrapWithOverflow" />

            <!-- Header Template Selection -->
            <Label Grid.Row="2" Grid.Column="0"  Margin="0,3,0,0" HorizontalAlignment="Left" VerticalAlignment="Bottom" Content="Select Header:" FontWeight="DemiBold" Foreground="DarkGray" />
            <telerik:RadComboBox x:Name="radComboHeaderTemplate" Grid.Row="3" Grid.Column="0" Width="120" Margin="0,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center" 
                                 ClearSelectionButtonVisibility="Visible" SelectedValue="{Binding TemplateHeaderID}" />

            <!-- Footer Template Selection -->
            <Label Grid.Row="2" Grid.Column="1" Margin="0,3,0,0" HorizontalAlignment="Left" VerticalAlignment="Bottom" Content="Select Footer:" FontWeight="DemiBold" Foreground="DarkGray" />
            <telerik:RadComboBox x:Name="radComboFooterTemplate" Grid.Row="3" Grid.Column="1" Width="120" Margin="0,0,0,0" HorizontalAlignment="Left" VerticalAlignment="Center" 
                                 ClearSelectionButtonVisibility="Visible" SelectedValue="{Binding TemplateFooterID}" />

        </Grid>
    </DataTemplate>

当我的窗口加载时，我从我的数据库中下载集合数据并将其存储到本地集合中。请注意，有两个集合，一个用于我的 DataTemplate 中的 2 个组合框。

    //Header Templates
    private ObservableCollection<TemplateHeaderFooter> templatesHeader = new ObservableCollection<TemplateHeaderFooter>();

    //Footer Templates
    private ObservableCollection<TemplateHeaderFooter> templatesFooters = new ObservableCollection<TemplateHeaderFooter>();



    //--- Constructors ---

    public PrintTemplateGroupsConfigWindow()
    {
        InitializeComponent();

        //Download Data From DB
        this.templatesHeader = TemplateHeaderFootersDB.GetAllTemplatesOfType(1);
        this.templatesFooters = TemplateHeaderFootersDB.GetAllTemplatesOfType(2);
    }

如何将集合 Data templatesFooters和templatesHeader放入其各自 ComboBoxes 的 ItemsSources 中？

数据模板用于列表框。

<telerik:RadListBox x:Name="lstBoxPrintGroupTemplates" Height="300" Width="280" ItemsSource="{Binding}" IsEnabled="False"  
                            ItemTemplate="{StaticResource ListBoxCustomTemplate}" Style="{StaticResource DraggableListBox}" >

非常感谢。任何帮助表示赞赏。

在集合的变量上定义属性包装器，然后您可以将它们绑定到组合框，如下所示：

ItemsSource="{Binding TemplatesHeader, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"

public ObservableCollection<TemplateHeaderFooter> TemplatesHeader
{
  get{return templatesHeader;}
}

同样，您可以为其他财产做
