Thank you for contacting us.
It turns out this behavior is caused by an inaccuracy in the way the position of the DropVisualPlaceHolder is calculated. We updated your Telerik points for bringing this to our attention. The issue is logged in our system, you can track its progress here
. We're sorry for any inconvenience caused.
Fortunately, we were able to come up with a workaround by creating a custom DropVisualProvider.
Please take a look at the attached project and tell us if it works for you.
Hope this helps.
