分配选择模式到Gridview

问题描述：

<GridView x:Name="MyGrid" SelectionMode="Multiple" IsItemClickEnabled="True" IsRightTapEnabled="False" RightTapped="MyGrid_RightTapped" BorderThickness="0" ItemClick="GridView_ItemClick"> 
    <GridView.ItemTemplate> 
     <DataTemplate> 
      <StackPanel Width="290" Height="80" HorizontalAlignment="Center" BorderThickness="0" Margin="5,5,5,5" Background="#596A82"> 
       <TextBlock FontSize="20" Margin="10,5,10,5" Text="{Binding Brand}" HorizontalAlignment="Left" Foreground="#FFFFFF"/> 
       <TextBlock FontSize="12" Margin="10,0,10,0" Text="{Binding Model}" HorizontalAlignment="Left" Foreground="#BDC3CD"></TextBlock> 
       <TextBlock FontSize="12" Margin="10,4,10,5" Text="{Binding Color}" HorizontalAlignment="Left" Foreground="#BDC3CD"></TextBlock> 
      </StackPanel> 
     </DataTemplate> 
    </GridView.ItemTemplate> 
</GridView>

而且我有一个按钮，当它点击时，我需要在GridView中将SelectionMode属性分配给多个。分配选择模式到Gridview

private void Button_Click(object sender, RoutedEventArgs e) 
{ 
    MyGrid.SelectionMode = SelectionMode.Multiple; 
}

但它不工作，并显示这样的错误。

无法隐式转换类型 'Windows.UI.Xaml.Controls.SelectionMode' 到 'Windows.UI.Xaml.Controls.ListViewSelectionMode'。一个明确的转换不存在（是否缺少强制转换？）

答

使用ListViewSelectionMode而不是SelectionMode

MyGrid.SelectionMode = ListViewSelectionMode.Multiple;
