MapControl: [shift] + drag rectangle. Any way to surpress?

Mike_Quetel — Thu, 27 Jun 2024 20:17:43 GMT

A user brought this behavior to my attention recently, and I'm not sure when this was incorporated into the map control. The combination of holding down the shift button and dragging a rectangle performs a zoom-in which I am struggling to suppress. I used to take advantage of this combination for adding/removing either selected features or graphics... and this behavior now overrides everything else, seemingly to include the editor. Do I have any options here? MapViewInteractionOptions doesn't appear to have anything granular besides stopping any zoom in capability...

The feature isn't new. It's been there in every release, dating all the way back to the old Silverlight days.

If you're using WPF, you can use the PreviewMouseMove event and set e.Handled=true if the shift key is down to take over control.

Is it possible that the old SketchEditor suppressed it and the new editor doesn't? That's my theory.

Just dug in deeper and see the issue now. It's actually a bug-fix that was made. We didn't want the editor to continue reacting to mouse move when you're using key-combinations like shift. That means it'll fall through to the default zooming mode, so you can edit your geometry, but if you need to zoom in closer, you can still do the zoombox interaction.

OK thanks... at least I haven't completely lost my mind! I think rather than fighting the shift button combo, I'm just going to move over to using the ctrl button to signal that the user wants to modify an existing map selection vs create a new one. There's value to not overriding the zoom-in functionality

Sounds like a good idea. It did get us started to think about an easier way to remap/remove all key combinations and add custom key combos as well to make scenarios like this easier.

It would be really welcome to have more fine-grained control over these actions, to support specialized use cases. Appreciate your feedback!
