Is User Control in Asp.Net can be completely self contain?
<p>I am trying to make a UserControl that have all data process, initialize data, ajax, all self contain into one control.
So I can insert to anywhere on my Asp pages.</p>

<p>But the problem is, the UserControl contains a Script Manager and the Page that contain that User Control has a Script Manager too, so Asp doesn't allow me to have two Script Manager in one page.</p>

<p>In case like this, I wonder if UserControl can completely self contain?
Or the proper way of using UserControl is just using it like a template, and all the data process, event handler I have to do on the page that contains the UserControl?</p>

<p>Thanks.</p>

<p>======Edit:
 I guess I will just use ScriptManager.GetCurrent to check if page exists ScriptManager and add it otherwise. Thanks.</p>
