One alternative to fix this issue is:

Declare the library

using AjaxControlToolkit;

Then you can do something on these lines

private void InitControl()
{        
            //FIX - DROP DOWN
            ToolkitScriptManager scrManager = (ToolkitScriptManager)Page.Master.Controls[0].Controls[0].FindControl("manScript");
            scrManager.RegisterAsyncPostBackControl(ddlNewService_PortTelco);
}
