Calling Code Behind function without PostBack

Question

I am built an mp3 player that loads songs up randomly. I have a function in the CodeBehind page that runs a SQL query to pull a random record. I call the function during the PageLoad, and it works great. I'm trying to add a button that calls the function again, but without refreshing the page. I'm using an image button.

I looked into AJAX solutions, but from what I found, so it the Web Method can't call my getNext function.

I am fairly confident that my issue does not lie in my code, but in my design. If someone has a good ideas to point me in the right direction, I would be grateful.

//On Page

<asp:scriptmanager id="ScripManager1" runat="server" enablepagemethods="true" xmlns:asp="#unknown">

<script>

function SavePostions(object) {
PageMethods.SavePosition(object.attr('id'), object.position().left + "px", object.position().top + "px", object.css("height"), object.css("width"), function () { });
}

</script>

//Code Behind

[WebMethod]
public static void SavePosition(string id, string x, string y, string heght, string width)
{
//Do Your Thing
}

I actually tried this. In the "Do your thing" spot, I put, getSong(). I get,
"An object reference is required for the non-static field, method or property 'SiteMaster.getSong()'"

Seems you write the serverside method in the Masterpage. You must write it to Page codebehind. Event if you write that webmethod to the user control then it will not work. So you just create a page, then take ScriptMangager referenece to that page(either you do not take reference it from masterpage) then call webmethod which is written in that page code behind.
