UserControl inside Placeholder good/bad? + Postback problem
<p>Currently I'm working a bit with ASP.NET and trying to find the best way to navigate through pages. Right now I have an <code>UpdatePanel</code> which has a <code>Placeholder</code> inside it. This <code>Placeholder</code> will then add the <code>usercontrol</code> I need. </p>

<p>I've been looking around on the internet and some say that this is a really bad thing to do, while others use it without trouble. Is this whole <code>UserControl</code> inside <code>Placeholder</code> inside <code>updatepanel</code> good/bad?</p>

<p>While I've been trying to implement this I run into a problem with <code>postback</code>.
When I click a button on my "Main page" to add a new <code>UserControl</code> to the <code>Placeholder</code>, the Page. <code>IsPostback</code> is of course the same on the <code>UserControl</code> and therefore it will always be true here. </p>

<p>Am I doing something wrong or do I need to use a session variable to keep my <code>UserControlPostback</code> perhaps?</p>

<p>I'm open to all options, just need to find the preferred way.</p>
