What does script manager control actually do?
<p>I have a small doubt which I could not google the answer, So thought I could find the answer here.
Why should we add </p>

<pre><code> &lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt;
 &lt;/asp:ScriptManager&gt;
</code></pre>

<p>control in order to use </p>

<pre><code>  &lt;asp:UpdatePanel runat="server"&gt; in out aspx page.
</code></pre>

<p>hope some one can give the answer.</p>

<p>Thanks in Advance.</p>
