Question

Following is the web site environment I created:

1. I have a Master page.
2. I have created a Child page from it.
3. I have placed Script Manager on

Answer 1

Not sure what exactly you want here... you want to access the script manager of your master page or just the masterpage?

You can access the master page by Page.Master in code behind

Or

using System.Web.UI;
ScriptManager ScriptManager1 = (ScriptManager)Page.Master.FindControl("ScriptManager1") 
// to access the script manager of master page

or

Page.Master.Controls.Add(Your UserControl object) 
// to add the user control in your master page
