Javascript comfirmation popup not showing
<p>I am trying to validate some fields in DIV and if theres no validation error, I would show a comfirmation popup, below is my code, apparently the popup doesn't appear, if I remove the Page_ClientValidate(); and the popup will show. Please kindly advice. Thanks. </p>

<pre><code>&lt;asp:Button ID="uibtnVoucherIssuance" runat="server" Text="&lt;%$ Resources : Resources, uiIVouchers %&gt;"
OnClientClick="if(typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); if(Page_IsValid){return confirm('Proceed with voucher issuance?');}"
ValidationGroup="Issuance" /&gt;
</code></pre>
