在ListView上拖动当定义ItemsTemplate时

我正在开发一个UWP应用程序，在一个场景中我必须在ListView上添加拖放功能 . 但是，当定义ItemsTemplate时，DragItemsStarting事件不会触发 .

在一种情况下，当我通过选择其边框对ListViewItem执行拖动操作时，它运行良好，但是当我对项目进行拖动时它不起作用 .

Here is the Image for drag operation on items border:

这是XAML代码：

<ListView Grid.Row="3"
              ScrollViewer.IsScrollInertiaEnabled="True"
              ScrollViewer.VerticalScrollBarVisibility="Auto"
              ScrollViewer.VerticalScrollMode="Enabled"
              CanDragItems="True"
              CanReorderItems="True"
              ReorderMode="Enabled"
              AllowDrop="True"
              SelectionMode="Single"
              VerticalAlignment="Stretch"
              HorizontalAlignment="Stretch"
              DragItemsStarting="{x:Bind VM.DragItemsStarting, Mode=OneWay}"
              DragOver="{x:Bind VM.DragOver, Mode=OneWay}"
              Drop="{x:Bind VM.DragDrop, Mode=OneWay}"
              ItemsSource="{x:Bind ItemSource, Mode=OneWay}">

   <ListView.ItemTemplate>
            <DataTemplate x:DataType="model:Model">
                <Button HorizontalAlignment="Stretch"
                        HorizontalContentAlignment="Stretch"
                        Command="{Binding DataContext.PageCommand, ElementName=pageMain}">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="*" />
                            <RowDefinition Height="10" />
                        </Grid.RowDefinitions>
                        <TextBlock Text="{x:Bind ShowName,Mode=OneWay}"
                                   VerticalAlignment="Center"
                                   HorizontalAlignment="Center"
                                   Foreground="Black"
                                   TextWrapping="WrapWholeWords"
                                   Margin="3" />
                        <ProgressBar Grid.Row="1"
                                     Margin="0"
                                     Value="25"
                                     Height="8"
                                     VerticalAlignment="Bottom"
                                     Foreground="Green" />
                    </Grid>
                </Button>
            </DataTemplate>
        </ListView.ItemTemplate>

有什么办法可以在完整的ListViewItem上执行拖动操作吗？
