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

TypeDescription
Operation as LayoutChangingEnum A LayoutChangingEnum expression that indicates the operation to be started.
The LayoutStartChanging event notifies your application once the user/control is about to being an operation. The LayoutEndChanging event notifies your application once the current operation ends. Use the PivotBarVisible property to enable or disable different properties of the control's pivot bar like: AutoHide, Undo/Redo support, and so on.

These events notify your application if any of the following operations occur:
