推荐答案

好吧，您的 TextBlock 不需要换行，因为您将 Width 指定为 Auto 因为它是 ColumnDefinition，它允许它采用所有 Width 来适应内容，即使以溢出为代价.您需要将列的宽度设置为*"以允许 TextWrapping 在请求的宽度超出允许范围时启动，或者使用 Binding 手动强制 MaxWidth 在其上使用

Well your TextBlock does not need to wrap since your specifying Width as Auto for it's ColumnDefinition which allows it to take all the Width it needs to fit Content even at the cost of overflowing. You either need to set the Column's Width to "*" to allow the TextWrapping to kick in when requested width exceeds allowable or manually force a MaxWidth on it using a Binding like

<TextBlock Name="tbText" Grid.Row="1" MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}, Path=ActualWidth}" Text="{Binding Path=Data}" TextWrapping="Wrap" />
