Remarks
End-users can expand/collapse nodes using the expand button. The AllowExpandAnimation property specifies whether to use animation effects when expanding/collapsing nodes. If this property is set to Default, the actual behavior depends on the WindowsFormsSettings.AnimationMode static setting. If the global setting is set to Default or EnableAll, the animation effects are enabled; otherwise, they are disabled.
If you subscribe to the TreeList.BeforeExpand, TreeList.BeforeCollapse, TreeList.AfterExpand or TreeList.AfterCollapse event and the AllowExpandAnimation setting is Default, the expand/collapse animation effects are forcibly disabled.
In code, you can expand/collapse a node using the TreeListNode.Expand, TreeList.ExpandAll, TreeList.CollapseAll, TreeList.ExpandToLevel and TreeList.CollapseToLevel methods. When expanding/collapsing nodes in code, the animation is always disabled, regardless of the AllowExpandAnimation property value.
