Hello Team,

We are using BVC2013. We want to customise "Gift Certificates" user control from "www\BVModules\Controls\GiftCertificates.ascx" path which is used on checkout module.

We have added following hidden field on GiftCertificates.ascx:
<asp:HiddenField ID="HdnGCResult" runat="server" Value="testval" ClientIDMode="Static" />

We have call client side function on click of AddGiftCertificateImageButton and set value to this hiddenfield using jquery in JS custom function as follows:
$('#HdnGCResult').val("121")

When we debug function value get set to this hidden field and also able to see in HTML while rendering HTML. When server side AddGiftCertificateImageButton_Click event occurred after calling client side event the newly assigned hidden field value (i.e. "121") not display on server side but hidden field displays "testval". Since check out page may be get refresh.

Could you please suggest how can we get hidden filed value which is set by jquery function?

Thank You.
