WPF - Drag an attachment from outlook

[ghost]

Can anyone give me some help with dragging an attachment from outlook into a web page hosted in CefSharp WPF. I understand that chromium has a fx for this but it still has to be implemented in CefSharp? Can anyone give some tips and I can try and do it in my own branch. Thanks.

Have you enabled drag and drop on the ChromiumWebBrowser?

https://docs.microsoft.com/en-us/dotnet/api/system.windows.uielement.allowdrop?view=net-5.0

As a starting point I'd add a breakpoint to
https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Wpf/ChromiumWebBrowser.cs#L1575

The CEF API https://github.com/chromiumembedded/cef/blob/4f28c5ffffd00f9a8fa67392e594e5207cb65158/include/cef_drag_data.h#L51

Hello,

AllowDrop is enabled on the CefSharp browser and drop operations are working from files.

We have a specific problem with dragging an outlook attachment to an embedded web page.

This is solved in the new WebView2 control so we are switching to embedded edge via this control.

Thanks

From the little I know about the WebView2 implementation in WPF it's not actually a native WPF control, it's a Win32 control (basically like hosting WinForms in WPF).

For what it's worth the CefSharp.Wpf.HwndHost package is indented to be a drop in replacement for those wishing to host the Win32 version in WPF. You will have all the same airspace issues.
