i have code like this:

```html
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Panel ID="Panel1" runat="server">
            <asp:Button ID="btnSaveBooks" runat="server" Text="Save" CssClass="col-md-4 form-control" Width="8%" ForeColor="White" BackColor="#333333" OnClick="btnSaveBooks_Click" />
            <asp:Button ID="btnActive" runat="server" Text="" OnClientClick="ohSnap('Task finished.', 'green');"/>
        </asp:Panel>
    </ContentTemplate>
</asp:UpdatePanel>
<div id="ohsnap"></div>

```

But how to active btnActive's OnClientClick in btnSaveBooks's OnClick event?
