推荐答案

不幸的是，文本框，RichTextBox中，并FlowDocument的观众永远纪念拖和拖放事件的处理，其中$ P $向上冒泡到你的处理器pvents他们。可以恢复拖和丢弃事件被截获这些控件以武力处理拖动和拖放事件（使用UIElement.AddHandler并设置handledEventsToo为true），并设置e.Handled假的处理程序。

Unfortunately, TextBox, RichTextBox, and FlowDocument viewers always mark drag-and-drop events as handled, which prevents them from bubbling up to your handlers. You can restore drag-and-drop events being intercepted by these controls by force-handling the drag-and-drop events (use UIElement.AddHandler and set handledEventsToo to true) and setting e.Handled to false in your handler.
