Hi.
ASP.NET Ajax controls are not immediately initialized. This is the reason why $find will return null.
You can use the pageLoad function where $find will return valid object:
function pageLoad()
{
var combo = $find("<%= RadComboBox1.ClientID %>");
alert(combo.get_text());
}
For more info about the pageLoad function and the client-side life-cycle in ASP.NET Ajax you can check the following article: http://www.asp.net/AJAX/Documentation/Live/overview/AJAXClientEvents.aspx
