Dialog argument in server side
<p>I am sending the reference of the parent window in <code>showmodaldailoge()</code> function as </p>

<pre><code>window.showmodaldialog("mypage.aspx", window, winsizeattributes)
</code></pre>

<p>since I don't want to use query string or session variable. Now I can access the variables of parent window at the client side of <code>mypage.aspx</code>. How can I access the parent window variables on server side of <code>mypage.aspx</code> ie in <code>Page_Load()</code>?</p>
