在此示例中，我无法使TextWrapping正常工作。有人能看到我在这里犯错吗？

                <GridViewColumn Header="Description" DisplayMemberBinding="{Binding Description}" Width="385">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock TextWrapping="Wrap" Text="{Binding}" Width="385"/>
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
                <GridViewColumn Header="Recover action" DisplayMemberBinding="{Binding Action}" Width="90"/>
            </GridView>
        </ListView.View>
    </ListView>

推荐答案

您同时设置了 DisplayMemberBinding 和 CellTemplate 。使用 CellTemplate 时，删除 DisplayMemberBinding 。还要删除 TextBlock 的 Width ，它将起作用

You are setting both DisplayMemberBinding and CellTemplate. Remove DisplayMemberBinding when you use CellTemplate. Also remove the Width for the TextBlock and it'll work

<ListView ...>
    <ListView.View>
        <GridView>
            <!-- ... -->
            <GridViewColumn Header="Description" Width="385">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock TextWrapping="Wrap" Text="{Binding Description}" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <!-- ... -->
        </GridView>
    </ListView.View>
</ListView>
