Loading Controls using an update panel

I'm currently trying to load controls onto the page dynamically and I was trying to use the UpdatePanel so that the controls could load w/o the page refreshing but I'm running into a problem with that. When I click the button that loads the control, it forces a refresh. How do i fix that?

here's the code

<%

@dotnet.itags.org.PageLanguage="C#"AutoEventWireup="true"CodeFile="Default.aspx.cs"Inherits="_Default" %>

Hi,

it seems that your aren't setting EnablePartialRendering="True" on the ScriptManager control.
I enabled that and I still couldn't get it to work. Any other suggestions?
I fixed it. I'm not quite sure what I did but it works lol.
