Edit PopUp Window from Rad Grid

[Biswajit]

I want to edit a row in the grid by opening a popup.
I am able to open a editable popup window on click of edit button in the grid by calling a java script function in ItemDataBound event at server side.  When i open the popup using window.radopen(), i am able to pass grid row data as arguments of radopen(). But in the pop up, page_load is not getting called and hence i am not able to catch the query string values. As a result i am unable to edit the row.
Please advise. Find the code below.

            }

Page load event in popup window is not fired when window opens and hence am not able to capture query strings passed 
through window.radopen()to new popup window. I can see the query strings values in the status bar of pop up window.
But i cant capture the query string and hence cant edit  grid row
If i can fire the page load event in pop up, then problem is solved.
Please advise on this or any alternate approaches.
