![]() This code checks first to see if it's allowed to load the file requested by the navigation. Neither the WinForms nor WPF (nor the ActiveX container in older Win32 apps) support drop operations, so if you do something like: WebBrowser.AllowDrop = true The Web Browser control itself in the host doesn't support Drag and Drop operations. To test drag and drop and clipboard operations make sure you always run as a non-elevated user. This can bite you if you run Visual Studio in Administrator mode and you try to debug your application. If you're running your application as Administrator Drag and Drop - even onto a main window and also non text clipboard operations like image pasting - is not allowed. Standard drag and drop operations that you can use on standard WPF or WinForms controls don't work with the Web browser control, so you have to resort to other approaches that I'll cover in this post so I can do this: ![]() ![]() NET and embedding the Web Browser control you're actually embedding an ActiveX control and there are some limitations on how the container interacts with drop events (and quite a few other things actually). The Web Browser Control is based on Internet Explorer and is actually an ActiveX control hosted inside of a container. Dragging content into the Web Browser control and capturing the content dropped is tricky.
