从PreviewMouseLeftButtonDown获取Listview或ListViewItem的索引

Question

So I have ListView with MyData object. And once I click the Left mouse key without release (so the item is not selected yet) I want to get my item ( ListViewItem or just the ListViewItem index...)

So this is what I have tried:

ListView listView;

private void listView_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var obj = e.Source;
    MyData myData = (MyData)(sender as ListView).SelectedItem;
    if (myData!= null)
    {
        // Do my stuff...
    }
}

Unfortunately, because the ListViewItem is not selected yet my myData is always null .

Any suggestions?

尝试检查((System.Windows.FrameworkElement)e.OriginalSource).DataContext 。
