Why do you want to disable the parent window?

You can try the following:
1. Keep a reference to the child window when you create it

var child_window = window.open()

2. When the parent window gains focus, check for the existence of this window.
3. If exists, give focus back to the child window.

A better alternative is to create an overlay/popup within the original window, e.g. like a lightbox or similar.

dropdown selected value gives me the popup and i should not be able to click on any other controls on the parent window until i close the popup window . that's the requirement. the script is in the dropdownlistselectedIndexChanged()method in codebehind.All my controls in my aspx page are with in update panel control and i could not tamper with it for some reason. I dont have html and body tags to use functions with in my aspx page. thats the reason why i had to go with script manager method . I am all over the internet and could not any thing . sorry to bore you with all this . I am new to asp and C#, both , any suggestion where to find some code or any other approach to get this done would be helpful

If you're having issues with the server-side code, ASP.NET, C#, update panels, etc., ask in the appropriate .NET forum.

As for a JavaScript solution, search for a lightbox alternative. There are some very good lightweight ones which will fulfil your requirement.
