为什么我的WPF应用程序有拖& Drop禁用（即使AllowDrop为真）？ [英] Why my WPF application has Drag & Drop disabled (even when AllowDrop is true)?

问题描述

我的WPF应用程序禁止从Windows资源管理器中删除文件，显示一个停止标志光标。

我试过设置AllowDrop属性（UIElement祖先）在主窗口上为true并包含控件，但根本没有运气，没有拖放事件被触发。

找到原因的任何想法或建议？

解决方案

已解决

问题是， VisualStudio（运行/调试）阻止了Windows的拖放操作下降机制。运行应用程序是独立的，使其工作，但无法交互调试。

此答案帮助很多：
Visual Studio 2010 WPF项目运行在调试或相关不允许拖放到任何控件

My WPF application inhibits the Drop of files from Windows Explorer, showing a Stop-sign cursor.

I've tried setting the AllowDrop property (that of the UIElement ancestor) to true on the main window and contained controls, but no luck at all, no drag-drop events are fired.

Any ideas or suggestions to find the cause?

解决方案

Solved!

The problem was that executing my app thru VisualStudio (run/debug) prevented the interop with Windows' drag & drop mechanism. Running the App as stand-alone makes it work, but cannot debug interactively.

This answer helped a lot: Visual Studio 2010 WPF Project ran in debug or relase will not allow drag and drop to any control
