How to reference a scriptmanager from HttpContext.Current.CurrentHandler?

Question

I reference the current page in a class with

Page page = HttpContext.Current.CurrentHandler as Page;

I know need to reference ScriptManager1. What the syntax ?

Thanks.

Answer 1

Or

Page page = HttpContext.Current.CurrentHandler as Page;

if (page != null)
{
    ScriptManager smgr = ScriptManager.GetCurrent(page);
}

Answer 2

ScriptManager sm = (ScriptManager)page.FindControl("ScriptManager1");

if(sm != null)
{
    // Control found

}
