Passing data from a aspx page to a aspx popup
<p>Following is the scenario I am facing, I have a aspx page in which I have added my ascx user control, I also have a <code>&lt;a href</code> control which call a js function to open a aspx popup.</p>

<p>when I open the popup, I need to send the data present in the ascx control to my popup. can you please guide me what method can I use to achieve this other than using session, as the data can be updated in many different places hence maintaining in session will be difficult.</p>

<p>Thanks</p>
