    In my WPF app, I am trying to improve the user experience of zooming in RadImageEditor.  The default experience of tedious zooming and scrolling is getting complaints from users and I agree. I'd very much like to support an experience such as the zoom feature in Microsoft Expression Blend, where the zoom center is always relative to the hovering mouse position.

    I happened to notice the AllowMouseWheelScaling property, which sounded interesting but I can find no description of what it is supposed to do. Only a variety of terse API docs which are of no help.   I tried setting that property on my RadImageEditor to true, but didn't see any change in the mouse wheel behavior (still scrolls)

    I'd like to know what this property is and how to use it, but also how I could possibly have found that out. Am I missing some resource with info such as this?

    Hi Robert,

    Thank you for contacting us and for the detailed description of your issue.

    RadImageEditor's AllowMouseWheelScaling property indicates whether wheel scaling is allowed. If it set to true, you will be able to scale by the mouse wheel while 'Ctrl' key is pressed. Otherwise this operation will not be allowed.

    Now, about your feature request - in the current implementation of the RadImageEditor you cannot scale to the mouse pointer, but I've logged that in our feedback portal, so you can vote for it and track its status there - Zoom to mouse pointer.

    If you have further questions, please do not hesitate to contact us again.

    Regards,
