I tried tween transform also but still,the tween transitions(from--->to)are not smooth, it happens with kind of pauses(Profiler shows High cpu usage in UIPanel.lateupdate).
There are two tweens playings simultaneously as shown in the above hierarchy(TweenAlpha + TweenTransform/TweenPosition).
Should the tweens act only on UIpanel,as my second tween(TweenTransform) is acting on empty Gameobject which is under UIPanel,holding all the widgets?
