Event on HoverMenu before it appears on screen

I have created <asp:table> and on each cell I have attached new <cc1:HoverMenuExtender>
Now i want to display different information in HoverMenu based on the id of the cell or id of the HoverMenuExtender when mouse is moved on that cell.

Is it possible to catch some event right before HoverMenu is displayed, where i can change information in that? How can I do that.

I want to keep logic for displaying information in one function so same function will be used for all <cc1:HoverMenuExtender> events.

Did you get an answer for this? I have to do something similar. When the user rollovers the cell, then different options will be loaded on the HoverMenu Exterder.
