Page.IsPostBack should be false but IsInAsyncPostBack shouldn't be. Do you have <xhtmlconformance mode="Legacy"> in your web.config file.

To call postback event , try below

XML

<Triggers>
 <asp:PostBackTrigger ControlID="Button1"  />
 </Triggers>
 </asp:UpdatePanel>

<postbacktrigger> Specifies a control and event that will cause a full page update (a full page refresh). This tag can be used to force a full refresh when a control would otherwise trigger partial rendering.
