Please help me understand AutoPostBack property of an ASP.NET control
<p>I'm learning about ASP.NET, mainly by following through a book, but also making an effort to actually do things along the way. But, I came across an explanation about list controls which I don't understand. This is what it says: </p>

<p>"[in the context of the Smart Tasks panel]...<em>the last option sets the AutoPostBack property of the control. With this option checked, the control will submit the page it's contained in back to the server as soon as the user chooses a new item from the list</em>"</p>

<p>Can you explain this statement for me? Thanks in advance for your help.</p>
