WPF DragDrop.DoDragDrop（用于RIGHT-Click？） [英] WPF DragDrop.DoDragDrop (for a RIGHT-Click?)

问题描述

在WPF中，我想使用右键单击启动拖放。像Windows资源管理器，右键单击，稍微移动，您可以让adorner指示一个拖放操作。不要动，当您放开按钮时，您将获得上下文菜单。

我已经启动了，但是当我调用DragDrop.DoDragDrop时，它会立即下降直到，它不等待鼠标向上。

我确实看到这个链接堆栈溢出问题，它指的是Silverlight文章，并且需要MouseCapture和它只适用于左按钮。从字面上看，似乎根本不可能在wpf中进行右键拖动操作（如windows）。我总是很难相信这样的事情:)（我没有尝试MouseCapture无效）

解决方案

找到解决方案问题在 MSDN论坛。主要思想是使用 DragDrop.AddQueryContinueDragHandler 。

In WPF I want to do initiate a drag-drop using the right click. Something like windows explorer, right click, move slightly and you get the adorner to indicate a drag drop in operation. Don't move and you get the context menu when you let up the button.

I have it all initiated but when I call the "DragDrop.DoDragDrop" it immediately falls right through, it doesn't wait for the mouse up.

I did see this link Stack Overflow Question and it refers to a Silverlight article and the need for the MouseCapture AND it only works with the Left button. Taken literally, it would seem that it is simply not possible to do a right click drag operation (like windows) in wpf. I always have a tough time believing such things :) (I did try the MouseCapture to no avail)

解决方案

Found solution for your problem on MSDN forums. The main idea is to use DragDrop.AddQueryContinueDragHandler.
