wpf - Scatterview Surface2应用程序WPF中的Datagrid

Question

我在 WPF 中的 scatterview 中放置了一个数据网格。我无法触摸并从数据网格中选择一行。在 touchdown 事件中，它返回所选单元格中的值。但它没有选择整行或突出显示它。

<Grid Background="{StaticResource WindowBackground}" >
    <s:ScatterView>
        <s:ScatterViewItem Width="500" Height="300"  CanRotate="False" Orientation="0" >
            <DataGrid  AutoGenerateColumns="True" TouchDown="DgTest_TouchDown" Name="DgTest" />
        </s:ScatterViewItem>
    </s:ScatterView>

Answer 1

尝试以下操作：

  // Declare event handlers for the Grid
    DgTest.PreviewTouchDown += new EventHandler<TouchEventArgs>(On_DgTest_PreviewTouchDown);
    DgTest.PreviewTouchUp += new EventHandler<TouchEventArgs>(On_DgTest_PreviewTouchUp );

    void On_DgTest_PreviewTouchDown(object sender, System.Windows.Input.TouchEventArgs e)
    {

    //You need to capture the touch before the ScatterViewItem handles its own touch which will    
    //block you from receiving the touch up event 

    DgTest.CaptureTouch(e.TouchDevice);
    e.Handled = true;

    }

    void On_DgTest_PreviewTouchUp (object sender, System.Windows.Input.TouchEventArgs e)
    {
    DgTest.ReleaseAllTouches();
    }
