Auto Close on drag drop - Docking/MDI for WPF Forum

Posted 8 years ago by Lutz Kretzschmar

Version: 17.1.0651

We have a window that can be set to auto-hide containing a list of files. These can be dragged onto controls on the main document surface (under the flyout). Sometimes the flyout obscures the target so we want to automatically auto-hide the flyout when drag has started.

I have figured out (what I think is a hacky way of) how do to this immediately on when drag/drop starts, but I was wondering if there's a way that the flyout can be made to hide only once the mouse has left its client area. Or is there a mechanism in the framework that supports this behavior?

Thanks,

- Lutz

Hi Lutz,

I don't believe we have anything built in for that, however if you can put together a simple sample project that shows this scenario, perhaps we can use that to test out some enhancements that would help handle it automatically for you. Please send any sample you come up with to our support address and in your email reference this thread. Be sure to remove any obj/bin folders from the ZIP and rename the .zip file extension so it doesn't get spam blocked. Thanks!

Ok, thanks. I ended up hooking into DragStart and walking up the visual tree to find the AutoHidePopup and then calling CloseImmediately() on that after about half a second delay.

We're in shipping mode, so currently don't have time to put together a sample, sorry.

Hi Lutz,

You also could do something like this, that might be a little easier:

dockSite.PrimaryDockHost.CloseAutoHidePopup(false, true);
