Panels and external pages

I have an ajax panel with a grid on it. When clicking on the grid a new window is opened with information from the grid. When finished i want to update the grid when the popup window is closed, how do i do it?

when opening the new window in your javascript, add the new window to a variable.

var nWindow = window.open("page")

the write a javascript timer to check whether the nWindow is null or not. If it is null then raise a postback to update the grid.
