By default, the AllowMoveObject property is exLeftClick, which indicates that with a simple click on the element, the user can move the element. The AllowMoveObject property specifies the keys combination so the user can move the element from the cursor. The AllowMoveSelection property indicates whether the entire selection is moved if an element in the selection is moved. Set the AllowMoveObject property on exDisallow, to prevent user to move any element in the surface. Use the AllowResizeObject property to specify whether the element can be resized at runtime. Use the Selectable property to specify whether the user can select or not an element from the surface. Since the user can not select an element, it can not move it too. The AllowMoveSurface property specifies the combination of keys that allows the user to move the surface. The control fires the LayoutStartChanging(exMoveObject) / LayoutEndChanging(exMoveObject) event when the user moves the object to a new position.
