组合框 TextWrap 绑定

问题描述

我有以下组合框

<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 应用到这个组合框并遵循答案中的代码片段 这里

I wish to apply Text Wrapping to this combobox and followed to code snippet from the answer here

<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

But this template is breaking the binding and the combobox displays no values. Any help would be appreciated

推荐答案

想通了

<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>
