event LayoutStartChanging (Operation as LayoutChangingEnum)
Occurs when the control's layout is about to be changed.

TypeDescription
Operation as LayoutChangingEnum A LayoutChangingEnum expression that specifies the operation that begins.
The LayoutStartChanging event occurs once the user starts an operation on the surface, like creating / adding a new element to the surface. During the LayoutStartChaning event, you can call the CancelLayoutChanging method to cancel the specified operation. The LayoutEndChanging event notifies that the specified operation ends.

The operations being signaled by the LayoutStartChanging / LayoutEndChanging events are:

For instance, the following events occur when user creates an element on the surface:
