I am struggling with this problem for over a week. I have a datagrid
in my web part and a button column (which is actually a link button)
for selecting the row and passing a cell value to another web part.
What I want is when I place the cursor over the link button
named "select", I would like to display the values in that row of the
datagrid in a popup menu using AJAX. The next row values should be
displayed in the next row's select linkbutton and so on.

In a nutshell, it should be an AJAX hover panel/menu to be displayed
when the cursor is placed over the linkbutton named "select" of the
button column. Early response will be highly appreciated.
