Windows Phone 8.1通过按住选择列表视图中的项目

Question

is there a way to select an item in a listview with the holding event in Windows Phone 8.1?

If I use a single tap, I use this code and it works fine

private void LstMyListView_Tapped(object sender, TappedRoutedEventArgs e)
{
  MyItem myItem = LstMyListView.SelectedItem as MyItem;
}

myItem contains the data of my selected item

However, if I use this code

private void LstMyListView_Holding(object sender, HoldingRoutedEventArgs e)
{
  MyItem myItem = LstMyListView.SelectedItem as MyItem;
}

myItem results as null.

How do I get the selected item with hold event??

Thank you!

You should be able to retrive your item from DataContext and perform a cast, for example like this:

private void LstMyListView_Holding(object sender, HoldingRoutedEventArgs e)
{
    FrameworkElement element = (FrameworkElement)e.OriginalSource;
    if (element.DataContext != null && element.DataContext is MyItem)
    {
        MyItem selectedOne = (MyItem)element.DataContext;
        // rest of the code
    }
}
