How to Get List Item in Custom Context Menu?

Hi,

I would like to know, if I want to get a particular columns value when slecting context menu. How can I set that UrlAction.

I can form url from every item's column's value, i.e. each item should redirect to some dynamic url when clicked on context menu of particular item.

*dynamic url can be formed using values from item's column's value.

Please suggest. It would be very helpful.

Thanks in advance.
