public static bool IsAsyncPostBack(this Page page)

    var result = false;
    var scriptManager = ScriptManager.GetCurrent(page);
    if (scriptManager != null)
    {

Need your complete block of code, the above is incomplete. Cant see where </asp:ConfirmLinkButton> opens for example. — Gabe

Try

Page.IsAsyncPostBack

Page class has a property: Page.IsPostBack. you should not use () to access a property of any class. This is the reason you are getting this error.

It looks like you have a control named 'ConfirmButton' in the local namespace. You should rename this control, since that identifier is already used as a namespace name.

It's trying to cast an item to type ConfirmButton.Controls.ConfirmLinkButton, so you have a root namespace with the name ConfirmButton and a control with the identifier ConfirmButton. You shouldn't use a namespace name as the identifier for an object or you will run into problems like this.
