Window C launches from window P using window.open? I think you want window.opener:

Hello,

Thank you for your reply.

But i am open a new child window as a popup window.

Here is my code so i could get window.opener its always null.

popupProgress.SetContentUrl("ShowProgress.aspx"); popupProgress.Show();

So i just need to hide my popup from this page ShowProgress.aspx where i opened this popup from Parent.aspx.

Can you please give me some idea.

Hi Ruchita, are SetContentUrl and Show() defined in a JavaScript library? You may want to check the library documentation on how to access the opener from the child window.

Sorry but i could get your point. Can you explain me in more details.

Hi Ruchita, your code seems to use objects and functions that are not built-in JavaScript objects and functions. That is the reason I think they must be defined in a library (external script) -- the one that defines the popupProgress object. Typically you would incorporate a library into your page using

<script src="somelibrary.js" type="text/javascript"></script>

So I suggest making sure the library is up-to-date and if that doesn't help, check on whether there is any support for it from the developer/vendor.
