Getting order Index of element in order List

[hamidh2]

I'm using the OrderList for rendering a list of categories.
I want to change the order of each category in that list via drag and drop but it seems there is not way to detect index of each element in that list before and after reordering!!!
by the way is there any way to detect such a thing???
