File Upload in Update Panel[^]

You can refer this link, and below info may help you to stop refreshing entire page

Tag

Description

<asp:asyncpostbacktrigger xmlns:asp="#unknown">

Specifies a control and event that will cause a partial page update for the UpdatePanel that contains this trigger reference.

<asp: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.
