Parse url from javascript popup in ASP.net
<p>I am developing web app using ASP.NET and i am also using javascript in the gridview header as TemplateField to open a window like this,</p>

<pre><code>&lt;a href="javascript:var popup = window.open('PopUp.aspx?+Value','Popup','width=200,height=200');
</code></pre>

<p>What I need to do in the "PopUp.aspx" code behind is to parse "Value" from "PopUp.aspx?+Value" in order for display a text based the value of "Value".</p>

<p>How do I get the "Popup.aspx?+Value from the PopUp.aspx?</p>

<p>Thanks.</p>
