Avoid moving shapes outside diagram

[David Navarro]

Hi,

is there any way to avoid moving shapes outside the diagram or to avoid overlapping shapes?

This could be interesting to design layout editors like floorplants, etc

Best Regards,

David

Hi David Navarro,

 There is the PreviewDrag routed event that is raised when the drag is about to finish, but you can handle that event, thus canceling the action if you calculate that the new position is not correct in terms of application logic (it is outside the viewport or is over other shape...). At the end  the shape will return it's original position. It is very easy to follow pattern but if you need more details, please let us know.

Thank you Miro Miroslavov,

Could you give me more details about how to cancel the drag action from the PreviewDrag event?

Greetings,

Hello David Navarro,

 I kind of mislead you with my previous post, because the PreviewDrag event is fired at the beginning of the dragging. However I managed to create working example of the mentioned functionality for you using the Drag and PreviewDrag events.
Please have a look at let us know if this is what you need.
