Well your TextBlockdoes not need to wrap since your specifying Widthas Autofor it's ColumnDefinitionwhich allows it to take all the Widthit needs to fit Content even at the cost of overflowing. You either need to set the Column's Width to "*" to allow the TextWrappingto kick in when requested width exceeds allowable or manually force a MaxWidthon it using a Binding like
嗯，你TextBlock不需要因为你的指定包装Width作为Auto它的ColumnDefinition允许它把所有的Width需要，即使在四溢的成本，以适应内容。您需要将列的宽度设置为“*”以允许TextWrapping在请求的宽度超过允许时启动，或者MaxWidth使用 Binding手动强制 a在它上面
<TextBlock Name="tbText" Grid.Row="1" MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}, Path=ActualWidth}" Text="{Binding Path=Data}" TextWrapping="Wrap" />
