ComboBox TextWrap绑定

Question

我有以下ComboBox

<ComboBox x:Name="TaskText" Text="{Binding TaskNameBinding}" ItemsSource="{Binding 
    taskList, ElementName=MainWin}" SelectedValuePath="_id" DisplayMemberPath="_name" 
    Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="90"/>

我希望将Text Wrapping应用于此组合框并按照代码片段here

进行操作

<ComboBox x:Name="TaskText" ItemsSource="{Binding taskList, ElementName=MainWin}" 
    SelectedValuePath="_id" DisplayMemberPath="_name" Background="Yellow" Padding="0" 
    Margin="0" BorderThickness="0" Width="90">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding TaskNameBinding}" 
                TextTrimming="CharacterEllipsis" />
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

但是这个模板打破了绑定，组合框没有显示任何值。任何帮助将不胜感激

想出来

<ComboBox x:Name="TaskText" Text="{Binding TaskNameBinding}" ItemsSource="{Binding taskList, ElementName=MainWin}" SelectedValuePath="_id" DisplayMemberPath="_name" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="90">
                        <ComboBox.ItemTemplate>
                            <DataTemplate>
                                <TextBlock 
                                Text="{Binding _name}" 
                                TextWrapping="Wrap" />
                            </DataTemplate>
                        </ComboBox.ItemTemplate>
                    </ComboBox>
