How to select multiple label controls on run time?, and how

I'm using a c# windows application. need an option for "Align Lefts" and "Align Tops" like windows form controls align tool.

I have used "Control. Draggable" package to moving the label controls on run time and need below option:

In runtime,

1. Align lefts button:

-- if I select label2, label3, and label4 & click to Align left button, then label3, and label4 should move in X position location same as label2 X position.

2. Align Tops button

-- if I select label3, label1, and label2 & click to Align Tops button, then label2, and label1 should move in Y position location same as label3 Y position.

i attached the video link and sample sources code. please suggest me, how to implement this option on run time.
