ListView DragDrop Scrollbar在WPF中不起作用 [英] ListView DragDrop Scrollbar not working in WPF

问题描述

亲爱的，



我试图拖动列表视图项目，我可以做到，但是当我尝试拖动滚动条时，我无法做到它就像在mousemove事件中完成了一样。



这是我的代码，

Dear all,

I am trying to drag list view items and I could do it, but when I try to drag the scroll bar, I could not do it as dragdrop was done in mousemove event.

Here is my code,

private void listView_Testcase_PreviewMouseMove(object sender, MouseEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                sourcelistview = (ListView)sender;

                foreach (object selItem in _selItems)
                {
                    if (!sourcelistview.SelectedItems.Contains(selItem))
                        sourcelistview.SelectedItems.Add(selItem);

                }
                if (sourcelistview.SelectedItems.ToString() != null)
                {
                    DragDrop.DoDragDrop(sourcelistview, sourcelistview.SelectedItems.ToString(), DragDropEffects.Copy);
                }

                else { return; }
            }
        }
