An AllowKeysEnum expression that specifies the keys combination so the user can
move a node from one parent to another.
By default, the AllowMoveNode property is exLeftClick +
exSHIFTKey. This means that if you single click the left mouse button on the
node while the SHIFT key is pressed, you can drag the node to a new parent. You can use the NodeFromPoint
property to get the node from the current position. The Parent
property specifies the parent node. The LayoutStartChanging(exMoveNode)
event notifies your application once the user starts dragging a node. The LayoutEndChanging(exMoveNode)
event notifies your application once user drops the node to a new position.
The DragOutsideDef property
customizes the speed to scroll the control's content while user moves nodes by
drag and drop then outside of the control's client area.
