将行为附加到UWP中的网格控件

Question

我正在UWP的Telerik RadDataGrid控件内使用一个网格，我已将刷卡行为附加到该网格上。它已连接，但未触发ManipulationCompleted事件。

delete ac
    from s_articles_categories ac join
         (select articleId, categoryid, min(id) as min_id
          from s_articles_categories
          where categoryID = 2153
          group by articleId, categoryid
         ) ac2
         on ac2.articleId = ac.articleId and
            ac2.categoryid = ac.categoryid and
            ac.id > ac2.min_id

在LeftSwipe行为中，我在OnAttached方法中编写了以下代码

<telerikGrid:RadDataGrid x:Name="MyDataGrid">
   <telerikGrid:RadDataGrid.Columns>
      <telerikGrid:DataGridTemplateColumn x:Name="DescriptionColumn"
         SizeMode="Stretch"
         CanUserSort="True"
         SortDirection="{Binding DataContext.SortingDirection,ElementName=gdRoot, Mode=TwoWay}"
         CanUserReorder="False">
         <telerikGrid:DataGridTemplateColumn.Header>
            <Grid HorizontalAlignment="Stretch">

               </Grid.ColumnDefinitions>
               <TextBlock Text="Description" HorizontalAlignment="Stretch" />
               <ToggleSwitch Grid.Column="1"

                  HorizontalAlignment="Left" />
