i can find out the answer it is working
just write the java script like this

<script type="text/javascript">
    var updateProgress = null;

    function postbackButtonClick() {
        updateProgress = $find("<%= UpdateProgress1.ClientID %>");
        window.setTimeout("updateProgress.set_visible(true)", updateProgress.get_displayAfter());
        return true;
    }
</script>

after that

<asp:UpdatePanel runat="server">
        <Triggers>
            <asp:PostBackTrigger ControlID="IBtnSave" />
        </Triggers>

button onclick event just call that function like this

<asp:Button ID="IBtnSave" runat="server" Text="Save" CssClass="art-button" 
                                            ClientIDMode="Static" onclick="IBtnSave_Click" OnClientClick="return postbackButtonClick();"/>
