How can items drag in both the directions Left to Right and Right to Left ?

[sagarcool89]

Hello , I am developing one application. Its having functionality of comparison between products information.

I have used Horizontal GridView for showing comparison of products. Its running fine,but draggable object is moving only in one direction, its Left To Right. I want direction to be Right to Left.

Gridview size : (320.0 , 370.0)
Items size : (140.0 , 340.0)

Please suggest your solution. I need it very urgently.

Thanks, Waiting for your quick feedback.
